Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation	Business Description and Basis of Presentation Description of Business The accompanying audited consolidated financial statements reflect the financial position, results of operations, comprehensive income, cash flows, and changes in shareholders' equity of Sensata Technologies Holding plc ("Sensata plc"), a public limited company incorporated under the laws of England and Wales, and its wholly-owned subsidiaries, collectively referred to as the "Company," "Sensata," "we," "our," and "us." Prior to March 28, 2018 , our parent company issuer was Sensata Technologies Holding N.V. ("Sensata N.V."), which was incorporated under the laws of the Netherlands. On March 28, 2018 , Sensata plc completed a cross-border merger (the "Merger") with Sensata N.V., which changed the location of our incorporation from the Netherlands to England and Wales, but did not change the business being conducted by us or our subsidiaries. We are a global industrial technology company that develops, manufactures, and sells sensors, sensor-based solutions, controls, and other products used in mission-critical systems and applications that create valuable business insights for our customers and end users. Our sensors are devices that translate a physical parameter, such as pressure, temperature, or position, into electronic signals that our customers’ products and solutions can act upon. These actionable insights lead to products that are safer, cleaner and more efficient, more electrified, and increasingly more connected. Our sensor-based solutions can be comprised of various sensors, controllers, receivers, and software, which provide comprehensive solutions to critical problems. Our controls are devices embedded within systems to protect them from excessive heat or current. Sensata plc conducts its operations through subsidiary companies that operate business and product development centers primarily in Belgium, Bulgaria, China, Germany, Japan, the Netherlands, South Korea, the United Kingdom (the "U.K."), and the United States (the "U.S."); and manufacturing operations primarily in Bulgaria, China, Malaysia, Mexico, the U.K., and the U.S. We operate in, and report financial information for, the following two segments: Performance Sensing and Sensing Solutions. Refer to Note 20, "Segment Reporting," for additional information related to each of our segments. Basis of Presentation The accompanying audited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and present separately our financial position, results of operations, comprehensive income, cash flows, and changes in shareholders’ equity. All intercompany balances and transactions have been eliminated. All U.S. dollar ("USD") and share amounts presented, except per share amounts, are stated in thousands, unless otherwise indicated. Certain reclassifications have been made to prior periods to conform to current period presentation.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in accordance with U.S. GAAP requires us to exercise our judgment in the process of applying our accounting policies. It also requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies at the date of the financial statements and the reported amounts of net revenue and expense during the reporting periods. Estimates are used when accounting for certain items such as allowance for doubtful accounts and sales returns, depreciation and amortization, inventory obsolescence, asset impairments (including goodwill and other intangible assets), contingencies, the value of certain equity awards and the measurement of share-based compensation, the determination of accrued expenses, certain asset valuations including deferred tax asset valuations, the useful lives of plant and equipment, measurement of our post-retirement benefit obligations, and the identification, valuation, and determination of useful lives of identifiable intangible assets acquired in business combinations. The accounting estimates used in the preparation of the consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained, and as the operating environment changes. Actual results could differ from those estimates. Revenue Recognition We recognize revenue to depict the transfer of promised goods to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods. In order to achieve this, we use the five step model outlined in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers . This five step model requires us to identify the contract with the customer, identify the performance obligation(s) in the contract, determine the transaction price, allocate the transaction price to the performance obligation(s), and recognize revenue when (or as) we satisfy the performance obligation(s). The vast majority of our contracts (as defined in FASB ASC Topic 606) are customer purchase orders ("POs" and each, a "PO") that require us to transfer specified quantities of tangible products to our customers. These performance obligations are generally satisfied within a short period of time. Amounts billed to our customers for shipping and handling after control has transferred are recognized as revenue and the related costs that we incur are presented in cost of revenue. In determining the transaction price, we evaluate whether the consideration promised in the contract includes a variable amount and, if applicable, we include in the transaction price some or all of an amount of variable consideration only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration may be explicitly stated in the contract or implied based on our customary practices. Examples of variable consideration present in our contracts include rights of return, in the case of a defective or non-conforming product, and trade discounts, including early payment discounts and retrospective volume discounts. Such variable consideration has not historically been material in relation to our net revenue. Our contract terms generally require the customer to make payment shortly after (that is, less than one year) the shipment date. In such instances, we do not consider the effects of a significant financing component in determining the transaction price. Lastly, we exclude from our determination of the transaction price value-added tax and other similar taxes. Our performance obligations are satisfied, and revenue is recognized, when control of the product is transferred to the customer. The transfer of control generally occurs at the point in time the product is shipped from our warehouse or, less often, at the point in time it is received by the customer, depending on the specific terms of the arrangement. Many of our products are designed and engineered to meet customer specifications. These activities, and the testing of our products to determine compliance with those specifications, occur prior to any revenue being recognized. Products are then manufactured and sold to customers. However, in certain cases, pre-production activities are a performance obligation in a customer PO, and revenue is recognized when the performance obligation is satisfied. Customer arrangements do not involve post-installation or post-sale testing and acceptance. Our standard terms of sale provide our customers with a warranty against faulty workmanship and the use of defective materials, which is not considered a distinct performance obligation in accordance with FASB ASC Topic 606. Depending on the product, we generally provide such warranties for a period of twelve to eighteen months after the date we ship the product to our customer or for a period of twelve months after the date the customer resells our product, whichever comes first. Our liability associated with this warranty is, at our option, to repair the product, replace the product, or provide the customer with a credit. We do not offer separately priced extended warranty or product maintenance contracts. We also sell products to customers under negotiated agreements or where we have accepted the customer’s terms of purchase. In these instances, we may provide additional warranties for longer durations, consistent with differing end market practices, and where our liability is not limited. In addition, many sales take place in situations where commercial or civil codes, or other laws, would imply various warranties and restrict limitations on liability. Refer to Note 3, "Revenue Recognition," for additional information related to the net revenue recognized in the consolidated statements of operations. Share-Based Compensation We measure at fair value any new or modified share-based compensation arrangements with employees, such as stock options and restricted securities, and recognize as compensation expense that fair value over the requisite service period as required in accordance with FASB ASC Topic 718, Compensation—Stock Compensation . Share-based compensation expense is generally recognized as a component of selling, general and administrative ("SG&A") expense, which is consistent with where the related employee costs are presented, however, such costs, or a portion thereof, may be capitalized provided certain criteria are met. Share-based awards may be subject to either cliff vesting (i.e., the entire award vests on a particular date) or graded vesting (i.e., portions of the award vest at different points in time). In accordance with FASB ASC Topic 718, compensation expense associated with share-based awards subject to cliff vesting must be recognized on a straight-line basis. For awards without performance conditions that are subject to graded vesting, companies have the option to recognize compensation expense either on a straight-line or accelerated basis. We have elected to recognize compensation expense for these awards on a straight-line basis. However, awards that are subject to both graded vesting and performance conditions must be expensed on an accelerated basis. We estimate the fair value of options on the grant date using the Black-Scholes-Merton option-pricing model. Key inputs and assumptions used in this model are as follows: • The fair value of the underlying ordinary shares. This is determined as the closing price of our ordinary shares on the New York Stock Exchange (the "NYSE") on the grant date. • The expected term. This is determined based upon our own historical average term of exercised and outstanding options. • Expected volatility. We consider our own historical volatility, as well as our implied volatility, in estimating expected volatility for stock options. Implied volatility provides a forward-looking indication and may offer insight into expected volatility. • Risk-free interest rate. The risk-free interest rate is based on the yield for a U.S. Treasury security having a maturity similar to the expected term of the related option grant. • Expected dividend yield. The dividend yield of 0% is based on our history of having never declared or paid any dividends on our ordinary shares, and our current intention of not declaring any such dividends in the foreseeable future. Restricted securities are valued using the closing price of our ordinary shares on the NYSE on the grant date. Certain of our restricted securities include performance conditions that require us to estimate the probable outcome of the performance condition. Compensation expense is recognized if it is probable that the performance condition will be achieved. Under the fair value recognition provisions of FASB ASC Topic 718, we recognize share-based compensation net of estimated forfeitures. Accordingly, we only recognize compensation expense for those awards expected to vest over the requisite service period. Compensation expense recognized for each award ultimately reflects the number of units that actually vest. Refer to Note 4, "Share-Based Payment Plans," for additional information related to share-based compensation. Financial Instruments Our financial instruments include derivative instruments, debt instruments, debt and equity investments, and trade accounts receivable. Derivative financial instruments: We account for our derivative financial instruments in accordance with FASB ASC Topic 820, Fair Value Measurements and Disclosures and FASB ASC Topic 815, Derivatives and Hedging . In accordance with FASB ASC Topic 815, we recognize all derivatives on the balance sheet at fair value. The fair value of our derivative financial instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. These analyses utilize observable market-based inputs, including foreign currency exchange rates and commodity forward curves, and reflect the contractual terms of these instruments, including the period to maturity. Derivative instruments that are designated and qualify as hedges of the exposure to changes in the fair value of an asset, liability, or commitment, and that are attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments that are designated and qualify as hedges of the exposure to variability in expected future cash flows are considered cash flow hedges. Derivative instruments may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Currently, our derivative instruments that are designated as accounting hedges are all cash flow hedges. We also hold derivative instruments that are not designated as accounting hedges. The accounting for changes in the fair value of our cash flow hedges depends on whether we have elected to designate the derivative as a hedging instrument for accounting purposes and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. In accordance with FASB ASC Topic 815, both the effective and ineffective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recognized in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period in which the hedged forecasted transaction affects earnings. Changes in the fair value of derivative instruments that are not designated as accounting hedges are recognized immediately in other, net. Refer to Note 16, "Shareholders' Equity," and Note 19, "Derivative Instruments and Hedging Activities," for additional information related to the reclassification of amounts from accumulated other comprehensive loss into earnings. We present the cash flows arising from our derivative financial instruments in a manner consistent with the presentation of cash flows that relate to the underlying hedged items. We incorporate credit valuation adjustments to appropriately reflect both our own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of non-performance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. We do not offset the fair value amounts recognized for derivative instruments against fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral. We maintain derivative instruments with major financial institutions of investment grade credit rating and monitor the amount of credit exposure to any one issuer. We believe there are no significant concentrations of risk associated with our derivative instruments. Refer to Note 19, "Derivative Instruments and Hedging Activities," for additional information related to our derivative instruments. Debt Instruments: A premium or discount on a debt instrument is recognized on the balance sheet as an adjustment to the carrying amount of the debt liability. In general, amounts paid to creditors are considered a reduction in the proceeds received from the issuance of the debt and are accounted for as a component of the premium or discount on the issuance, not as an issuance cost. Direct and incremental costs associated with the issuance of debt instruments such as legal fees, printing costs, and underwriters' fees, among others, paid to parties other than creditors, are also reported and presented as a reduction of debt on the consolidated balance sheets. Debt issuance costs and premiums or discounts are amortized over the term of the respective financing arrangement using the effective interest method. Amortization of these amounts is included as a component of interest expense, net in the consolidated statements of operations. In accounting for debt refinancing transactions, we apply the provisions of FASB ASC Subtopic 470-50, Modifications and Extinguishments . Our evaluation of the accounting under FASB ASC Subtopic 470-50 is done on a creditor by creditor basis in order to determine if the terms of the debt are substantially different and, as a result, whether to apply modification or extinguishment accounting. In the event that an individual holder of existing debt did not invest in new debt, we apply extinguishment accounting. Borrowings associated with individual holders of new debt that are not holders of existing debt are accounted for as new issuances. Refer to Note 14, "Debt," for additional information related to our debt instruments and transactions. Equity Investments: We measure equity investments (other than those accounted for under the equity method, those that result in consolidation of the investee, and certain other investments) either at fair value, with changes to fair value recognized in net income, or in certain instances, by use of a measurement alternative prescribed in FASB ASC Topic 321, Investments - Equity Securities . Under the measurement alternative, such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Refer to Note 18, "Fair Value Measures," for additional information related to our measurement of financial instruments. Trade accounts receivable: Trade accounts receivable are recognized at invoiced amounts and do not bear interest. Trade accounts receivable are reduced by an allowance for losses on receivables, as described elsewhere in this Note 2. Concentrations of risk with respect to trade accounts receivable are generally limited due to the large number of customers in various industries and their dispersion across several geographic areas. Although we do not foresee that credit risk associated with these receivables will deviate from historical experience, repayment is dependent upon the financial stability of these individual customers. Our largest customer accounted for approximately 7% of our net revenue for the year ended December 31, 2019 . Allowance for Losses on Receivables The allowance for losses on receivables is used to present accounts receivable, net at an amount that represents our estimate of the related transaction price recognized as revenue in accordance with FASB ASC Topic 606. The allowance represents an estimate of probable but unconfirmed losses in the receivable portfolio. We estimate the allowance on the basis of specifically identified receivables that are evaluated individually for impairment and a statistical analysis of the remaining receivables determined by reference to past default experience. Customers are generally not required to provide collateral for purchases. The allowance for losses on receivables also includes an allowance for sales returns (variable consideration). Management judgments are used to determine when to charge off uncollectible trade accounts receivable. We base these judgments on the age of the receivable, credit quality of the customer, current economic conditions, and other factors that may affect a customer’s ability and intent to pay. Losses on receivables have not historically been significant. Goodwill and Other Intangible Assets Businesses acquired are recognized at their fair value on the date of acquisition, with the excess of the purchase price over the fair value of identifiable assets acquired and liabilities assumed recognized as goodwill. Intangible assets acquired may include either definite-lived or indefinite-lived intangible assets, or both. In accordance with the requirements of FASB ASC Topic 350, Intangibles—Goodwill and Other , goodwill and intangible assets determined to have an indefinite useful life are not amortized. Instead these assets are evaluated for impairment on an annual basis, and whenever events or business conditions change that could indicate that the asset is impaired. We evaluate goodwill and indefinite-lived intangible assets for impairment in the fourth quarter of each fiscal year, unless events occur which trigger the need for an earlier impairment review. Goodwill: We have identified six reporting units: Performance Sensing, Electrical Protection, Industrial Sensing, Aerospace, Power Management, and Interconnection. These reporting units have been identified based on the definitions and guidance provided in FASB ASC Topic 350. We periodically review these reporting units to ensure that they continue to reflect the manner in which the business is operated. Certain assets and liabilities relate to the operations of multiple reporting units. We allocate these assets and liabilities to the related reporting units based on methods that we believe are reasonable and supportable, and we apply that allocation method on a consistent basis from year to year. Other assets and liabilities, such as cash and cash equivalents and property, plant and equipment ("PP&E") associated with our corporate offices, and debt, we view as being corporate in nature. Accordingly, we do not assign these assets and liabilities to our reporting units. In the event we reorganize our business, we reassign the assets and liabilities among the affected reporting units using a reasonable and supportable methodology. As businesses are acquired, we assign assets acquired and liabilities assumed to a new or existing reporting unit as of the date of the acquisition. In the event a disposal group meets the definition of a business, goodwill is allocated to the disposal group based on the relative fair value of the disposal group to the retained portion of the related reporting unit. We have the option to first assess qualitative factors to determine whether a quantitative analysis must be performed. The objective of a qualitative analysis is to determine whether it is more likely than not that the fair value of a reporting unit is less than its net book value. If we elect not to use this option, or if we determine that it is more likely than not that the fair value of a reporting unit is less than its net book value, then we perform the first step of the quantitative analysis prescribed by FASB ASC Topic 350. In this step we compare the estimated fair values of our reporting units to their respective net book values, including goodwill, to determine whether there is an indicator of potential impairment. If the net book value of a reporting unit exceeds its estimated fair value, we conduct a second step in which we calculate the implied fair value of goodwill. If the carrying value of the reporting unit’s goodwill exceeds its calculated implied fair value, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of its identifiable assets and liabilities as if the reporting unit had been acquired in a business combination at the date of assessment, and the fair value of the reporting unit was the purchase price paid to acquire the reporting unit. The excess of the fair value of the reporting unit over the sum of the fair values of each of its identifiable assets and liabilities is the implied fair value of goodwill. The fair value measurements of our reporting units are categorized in level 3 of the fair value hierarchy. Indefinite-lived intangible assets: Similar to goodwill, we perform an annual impairment review of our indefinite-lived intangible assets in the fourth quarter of each fiscal year, unless events occur that trigger the need for an earlier impairment review. We have the option to first assess qualitative factors in determining whether it is more likely than not that an indefinite-lived intangible asset is impaired. If we elect not to use this option, or we determine that it is more likely than not that the asset is impaired, we perform a quantitative impairment review that requires us to estimate the fair value of the indefinite-lived intangible asset and compare that amount to its carrying value. We estimate the fair value by using the relief-from-royalty method, which requires us to make assumptions about future conditions impacting the value of the indefinite-lived intangible assets, including projected growth rates, cost of capital, effective tax rates, and royalty rates. Impairment, if any, is based on the excess of the carrying value over the fair value of these assets. Definite-lived intangible assets: Acquisition-related definite-lived intangible assets are amortized on an economic-benefit basis according to the useful lives of the assets, or on a straight-line basis if a pattern of economic benefits cannot be reliably determined. Capitalized software and capitalized software licenses are presented on the consolidated balance sheets as intangible assets. Capitalized software licenses are amortized on a straight-line basis over the lesser of the term of the license or the estimated useful life of the software. Capitalized software is amortized on a straight-line basis over its estimated useful life. Reviews are regularly performed to determine whether facts or circumstances exist that indicate that the carrying values of our definite-lived intangible assets are impaired. If we determine that such facts or circumstances exist, we estimate the recoverability of these assets by comparing the projected undiscounted net cash flows associated with these assets to their respective carrying values. If the sum of the projected undiscounted net cash flows is less than the carrying value of an asset, the impairment charge is measured as the excess of the carrying value over the fair value of that asset. We determine fair value by using the appropriate income approach valuation methodology, depending on the nature of the definite-lived intangible asset. Refer to Note 11, "Goodwill and Other Intangible Assets, Net," for additional information related to our goodwill and other intangible assets. Income Taxes We estimate our provision for income taxes in each of the jurisdictions in which we operate. The provision for income taxes includes both our current and deferred tax exposure. Our deferred tax exposure is measured using the asset and liability method, under which deferred income taxes are recognized to reflect the future tax consequences of differences between the tax bases of assets and liabilities and their financial reporting amounts at each balance sheet date, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to reverse or settle. The effect on deferred tax assets and liabilities of a change in statutory tax rates is recognized in the consolidated statements of operations as an adjustment to income tax expense in the period that includes the enactment date. In measuring our deferred tax assets, we consider all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed for all or some portion of the deferred tax assets. If it is determined that it is more likely than not that future tax benefits associated with a deferred tax asset will not be realized, a valuation allowance is provided. As a result, we maintain valuation allowances against the deferred tax assets in jurisdictions that have incurred losses in recent periods and in which it is more likely than not that such deferred tax assets will not be utilized in the foreseeable future. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Reform Act") was signed into law. The Tax Reform Act introduced two new U.S. tax base erosion provisions: the global intangible low-taxed income ("GILTI") and the base erosion and anti-abuse tax ("BEAT"). We elected to account for GILTI in the period in which it is incurred rather than adjusting our deferred tax assets for any future impacts of this provision. Similarly, we account for BEAT tax in the year incurred as a period expense only, and have followed the guidance found in the FASB Staff Q&A, Topic 740, No. 4, Accounting for the Base Erosion Anti-Abuse Tax , which states that an entity does not need to evaluate the potential of paying BEAT in future years on the realization of its deferred tax assets and liabilities. We have followed this guidance in our current tax calculation and evaluation of the realizability of our deferred tax assets. In accordance with FASB ASC Topic 740, Income Taxes , we record uncertain tax positions on the basis of a two-step process. First, we determine whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position. Second, for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the relevant tax authority. Significant judgment is required in evaluating whether our tax positions meet this two-step process. The more-likely-than-not recognition threshold must be met in each reporting period to support continued recognition of any tax benefits claimed, both in the current year, as well as any year which remains open for review by the relevant tax authority at the balance sheet date. Penalties and interest related to uncertain tax positions may be classified as either income taxes or another expense line item in the consolidated statements of operations. We classify interest and penalties related to uncertain tax positions within the provision for/(benefit from) income taxes line of the consolidated statements of operations. Refer to Note 7, "Income Taxes," for additional information related to our income taxes. Pension and Other Post-Retirement Benefits We sponsor various pension and other post-retirement benefit plans covering our current and former employees in several countries. The funded status of pension and other post-retirement benefit plans, recognized on our consolidated balance sheets as an asset, current liability, or long-term liability, is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. In general, the measurement date coincides with our fiscal year end, however, certain significant events, such as (1) plan amendments, (2) business combinations, (3) settlements or curtailments, or (4) plan mergers, may trigger the need for an interim measurement of both the plan assets and benefit obligations. Benefit obligations represent the actuarial present value of all benefits attributed by the pension formula as of the measurement date to employee service rendered before that date. The value of benefit obligations takes into consideration various financial assumptions, including assumed discount rate and the rate of increase in healthcare costs, and demographic assumptions, including compensation rate increases, retirement patterns, employee turnover rates, and mortality rates. We review these assumptions annually. Our review of demographic assumptions includes analyzing historical patterns and/or referencing industry standard tables, combined with our expectations around future compensation and staffing strategies. The difference between these assumptions and our actual experience results in the recognition of an actuarial gain or loss. Actuarial gains and losses are recorded directly to other comprehensive income or loss. If the total net actuarial gain or loss included in accumulated other comprehensive loss exceeds a threshold of 10% of the greater of the projected benefit obligation or the market related value of plan assets, it is subject to amortization and recorded as a component of net periodic benefit cost over the average remaining service lives of the employees participating in the pension or post-retirement benefit plan. The discount rate reflects the current rate at which the pension and other post-retirement liabilities could be effectively settled, considering the timing of expected payments for plan participants. It is used to discount the estimated future obligations of the plans to the present value of the liability reflected in the financial statements. In estimating this rate in countries that have a market of high-quality, fixed-income investments, we consider rates of return on these investments included in various bond indices, adjusted to eliminate the effects of call provisions and differences in the timing and amounts of cash outflows related to the bonds. In other countries where a market of high-quality, fixed-income investments does not exist, we estimate the discount rate using government bond yields or long-term inflation rates. The expected return on plan assets reflects the average rate of earnings expected on the funds invested to provide for the benefits included in the projected benefit obligation. To determine the expected return on plan assets, we use the fair value of plan assets and consider the historical returns earned by similarly invested assets, the rates of return expected on plan assets in the future, and our investment strategy and asset mix with respect to the plans’ funds. Changes to benefit obligations may also be initiated by a settlement or curtailment. A settlement of a defined benefit obligation is an irrevocable transaction that relieves us (or the plan) of primary responsibility for the defined benefit obligation and eliminates significant risks related to the obligation and the assets used to effect the settlement. The settlement of all or more than a minor portion of the pension obligation constitutes an event that requires recognition of all or part of the net actuarial gains or losses deferred in accumulated other comprehensive loss. Our policy is to apply settlement accounting to the extent our year-to date settlements for a given plan exceed the sum of our forecasted full year service cost and interest cost for that particular plan. A curtailment is an event that significantly reduces the expected years of service of active employees or eliminates for a significant number of employees the accrual of defined benefits for some or all of their future serv

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition We recognize revenue to depict the transfer of promised goods to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods. The vast majority of our revenue is derived from the sale of tangible products whereby control of the product transfers to the customer at a point in time, we recognize revenue at a point in time, and the underlying contract is a PO that establishes a firm purchase commitment for a short period of time. Our standard terms of sale provide our customers with a warranty against faulty workmanship and the use of defective materials. We do not offer separately priced extended warranty or product maintenance contracts. Refer to Note 2, "Significant Accounting Policies" for additional information. We have elected to apply certain practical expedients that allow for more limited disclosures than those that would otherwise be required by FASB ASC Topic 606, including (1) the disclosure of transaction price allocated to the remaining unsatisfied performance obligations at the end of the period and (2) an explanation of when we expect to recognize the related revenue. We believe that our end markets are the categories that best depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The following table presents net revenue disaggregated by segment and end market for the years ended December 31, 2019 , 2018 , and 2017 : Performance Sensing Sensing Solutions Total For the year ended December 31, For the year ended December 31, For the year ended December 31, 2019 2018 2017 2019 2018 2017 2019 2018 2017 Net revenue: Automotive $ 1,986,537 $ 2,076,834 $ 1,989,152 $ 42,446 $ 49,961 $ 50,463 $ 2,028,983 $ 2,126,795 $ 2,039,615 HVOR (1) 559,479 550,817 471,448 — — — 559,479 550,817 471,448 Industrial — — — 351,942 336,617 312,137 351,942 336,617 312,137 Appliance and HVAC (2) — — — 201,745 208,482 209,958 201,745 208,482 209,958 Aerospace — — — 176,505 164,294 150,782 176,505 164,294 150,782 Other — — — 131,977 134,622 122,793 131,977 134,622 122,793 Net revenue $ 2,546,016 $ 2,627,651 $ 2,460,600 $ 904,615 $ 893,976 $ 846,133 $ 3,450,631 $ 3,521,627 $ 3,306,733 __________________________________________ (1) Heavy vehicle and off-road (2) Heating, ventilation and air conditioning In addition, refer to Note 20, "Segment Reporting," for a presentation of net revenue disaggregated by product category and geographic region.

Share-based Payment Arrangement [Abstract]
Share-Based Payment Plans	Share-Based Payment Plans We issue share-based compensation awards under the Sensata Technologies Holding plc First Amended and Restated 2010 Equity Incentive Plan (the "2010 Equity Incentive Plan"). The purpose of the 2010 Equity Incentive Plan is to promote long-term growth and profitability by providing our present and future eligible directors, officers, and employees with incentives to contribute to, and participate in, our success. There are 10.0 million ordinary shares authorized for grants of awards under the 2010 Equity Incentive Plan, of which 2.5 million were available as of December 31, 2019 . Refer to Note 2, "Significant Accounting Policies," for additional information related to our to share-based compensation accounting policies. Share-Based Compensation Awards We grant option, restricted stock unit ("RSU"), and performance restricted stock unit ("PRSU") awards under the 2010 Equity Incentive Plan. For option and RSU awards vesting is typically subject only to continued employment and the passage of time. For PRSU awards vesting is also subject to continued employment and the passage of time, however the number of awarded units that ultimately vest also depends on the attainment of certain predefined performance criteria. Throughout this Annual Report on Form 10-K, RSU and PRSU awards are often referred to collectively as "restricted securities." Options A summary of stock option activity for the years ended December 31, 2019 , 2018 , and 2017 is presented in the table below (amounts have been calculated based on unrounded shares): Number of Options (thousands) Weighted-Average Exercise Price Per Option Weighted-Average Remaining Contractual Term (years) Aggregate Intrinsic Value Balance as of December 31, 2016 3,546 $ 35.67 6.3 $ 19,844 Granted 387 $ 43.67 Forfeited or expired (1 ) $ 32.03 Exercised (326 ) $ 22.86 $ 7,175 Balance as of December 31, 2017 3,606 $ 37.69 6.0 $ 50,130 Granted 307 $ 51.83 Forfeited or expired (39 ) $ 45.59 Exercised (172 ) $ 35.31 $ 3,143 Balance as of December 31, 2018 3,702 $ 38.89 5.3 $ 27,846 Granted 382 $ 46.92 Forfeited or expired (83 ) $ 48.92 Exercised (537 ) $ 28.21 $ 11,690 Balance as of December 31, 2019 3,464 $ 41.19 5.0 $ 44,696 Options vested and exercisable as of December 31, 2019 2,646 $ 39.49 4.0 $ 38,811 Vested and expected to vest as of December 31, 2019 3,385 $ 41.05 4.9 $ 44,145 A summary of the status of our unvested options as of December 31, 2019 , and of the changes during the year then ended, is presented in the table below (amounts have been calculated based on unrounded shares): Number of Options (thousands) Weighted-Average Grant-Date Fair Value Balance as of December 31, 2018 1,077 $ 13.98 Granted during the year 382 $ 13.90 Vested during the year (579 ) $ 13.41 Forfeited during the year (62 ) $ 14.39 Balance as of December 31, 2019 818 $ 14.33 The fair value of stock options that vested during the years ended December 31, 2019 , 2018 , and 2017 was $7.8 million , $5.5 million , and $5.6 million , respectively. Option awards granted to employees under the 2010 Equity Incentive Plan generally vest 25% per year over four years from the grant date. We recognize compensation expense for options on a straight-line basis over the requisite service period, which is generally the same as the vesting period. The options generally expire ten years from the date of grant. For options granted prior to April 2019 , except as otherwise provided in specific option award agreements, if a participant ceases to be employed by us, options not yet vested generally expire and are forfeited at the termination date, and options that are fully vested generally expire 60 days after termination of the participant’s employment. Exclusions to the general policy for terminated employees include termination for cause (in which case the options expire on the participant’s termination date) and termination due to death or disability (in which case any unvested options shall immediately vest and expire six months after the participant’s termination date). For options granted in or after April 2019 , the same terms apply, except that fully vested options expire 90 days after termination of the participant's employment for any reason other than termination for cause (in which case the options expire on the participant's termination date), termination due to due to death or disability (in which case the options expire one year after the participant's termination date), and termination for a qualified retirement (in which case options will continue to vest and expire ten years from the grant date). The weighted-average grant-date fair value per option granted during the years ended December 31, 2019 , 2018 , and 2017 was $13.90 , $15.70 , and $14.50 , respectively. The fair value of options was estimated on the date of grant using the Black-Scholes-Merton option-pricing model. The weighted-average key assumptions used in estimating the grant-date fair value of options for the years ended December 31, 2019 , 2018 , and 2017 are as follows: For the year ended December 31, 2019 2018 2017 Expected dividend yield 0.00 % 0.00 % 0.00 % Expected volatility 25.00 % 25.00 % 30.00 % Risk-free interest rate 2.35 % 2.62 % 2.08 % Expected term (years) 6.0 6.0 6.0 Fair value per share of underlying ordinary shares $ 46.92 $ 51.83 $ 43.67 Restricted Securities We grant RSU awards that cliff vest between one year and three years from the grant date, and we grant PRSU awards that cliff vest three years after the grant date. For PRSU awards, the number of units that ultimately vest depends on the extent to which certain performance criteria are met, as described in the table below. For restricted securities granted in or after April 2019, terms include provisions allowing continued or accelerated vesting for a qualified retirement. A summary of restricted securities granted in the years ended December 31, 2019 , 2018 , and 2017 is presented below: Percentage Range of Units That May Vest (1) 0.0% to 150.0% 0.0% to 172.5% 0.0% to 200.0% (Awards in thousands) RSU Awards Granted Weighted-Average PRSU Awards Granted Weighted-Average Grant-Date Fair Value PRSU Awards Granted Weighted-Average Grant-Date Fair Value PRSU Awards Granted Weighted-Average Grant-Date Fair Value 2019 298 $ 47.73 76 $ 46.92 138 $ 46.92 — $ — 2018 218 $ 51.05 63 $ 51.83 118 $ 51.83 — $ — 2017 182 $ 43.24 — $ — 183 $ 43.67 53 $ 43.33 __________________________________________ (1) Represents the percentage range of PRSU award units granted that may vest according to the terms of the awards. The amounts presented within this table do not reflect our current assessment of the probable outcome of vesting based on the achievement or expected achievement of performance conditions. Compensation expense for the year ended December 31, 2019 reflects our estimate of the probable outcome of the performance conditions associated with the PRSU awards granted in fiscal years 2019 , 2018 , and 2017 . A summary of activity related to outstanding restricted securities for fiscal years 2019 , 2018 , and 2017 is presented in the table below (amounts have been calculated based on unrounded shares): Restricted Securities (thousands) Weighted-Average Grant-Date Fair Value Balance as of December 31, 2016 920 $ 44.35 Granted 418 $ 43.44 Forfeited (35 ) $ 43.94 Vested (222 ) $ 42.24 Balance as of December 31, 2017 1,081 $ 44.43 Granted 399 $ 51.40 Forfeited (121 ) $ 48.28 Vested (240 ) $ 53.01 Balance as of December 31, 2018 1,119 $ 44.66 Granted (1) 555 $ 46.73 Forfeited (115 ) $ 47.07 Vested (454 ) $ 39.62 Balance as of December 31, 2019 1,105 $ 47.51 __________________________________________ (1) Includes 43 thousand PRSU awards granted due to greater than 100% vesting. Aggregate intrinsic value information for restricted securities as of December 31, 2019 , 2018 , and 2017 is presented below: As of December 31, 2019 2018 2017 Outstanding $ 59,526 $ 50,161 $ 55,271 Expected to vest $ 34,717 $ 44,203 $ 42,106 The weighted-average remaining periods over which the restrictions will lapse as of December 31, 2019 , 2018 , and 2017 are as follows: As of December 31, 2019 2018 2017 Outstanding 1.1 1.2 1.3 Expected to vest 1.0 1.2 1.4 The expected to vest restricted securities are calculated based on the application of a forfeiture rate assumption to all outstanding restricted securities as well as our assessment of the probability of meeting the required performance conditions that pertain to the PRSU awards. Share-Based Compensation Expense The table below presents non-cash compensation expense related to our equity awards, which is recognized within SG&A expense in the consolidated statements of operations, during the identified periods: For the year ended December 31, 2019 2018 2017 Stock options $ 6,552 $ 5,739 $ 6,046 Restricted securities 12,205 18,086 13,773 Share-based compensation expense $ 18,757 $ 23,825 $ 19,819 In fiscal years 2019 and 2018 , we recognized $3.2 million and $3.0 million of income tax benefit associated with share-based compensation expense. We recognized no such tax benefit in fiscal year 2017 . The table below presents unrecognized compensation expense at December 31, 2019 for each class of award, and the remaining expected term for this expense to be recognized: Unrecognized Compensation Expense Expected Recognition (years) Options $ 8,419 1.8 Restricted securities 14,789 1.5 Total unrecognized compensation expense $ 23,208

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective April 27, 2006 (inception), and concurrent with the completion of the acquisition of the Sensors & Controls business ("S&C") of Texas Instruments Incorporated ("TI") (the "2006 Acquisition"), we commenced filing tax returns in the Netherlands as a stand-alone entity. On March 28, 2018 , the Company reincorporated its headquarters in the U.K. We file income tax returns in the countries in which our subsidiaries are incorporated and/or operate, including Belgium, Bulgaria, China, France, Germany, Japan, Malaysia, Mexico, the Netherlands, South Korea, the U.S., and the U.K. The 2006 Acquisition purchase accounting and the related debt and equity capitalization of the various subsidiaries of the consolidated company, and the realignment of the functions performed and risks assumed by the various subsidiaries, are of significant consequence to the determination of future book and taxable income of the respective subsidiaries and Sensata as a whole. Refer to Note 2, "Significant Accounting Policies," for detailed discussion of the accounting policies related to income taxes. Effects of the Tax Cuts and Jobs Act The Tax Reform Act reduced the U.S. federal corporate tax rate from 35% to 21% , required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and created new taxes on certain foreign sourced earnings. In fiscal year 2017 we recognized a tax benefit related to the enactment-date effects of the Tax Reform Act resulting from the adjustment of our deferred tax assets and liabilities, net of the impact from recognizing the one-time transition tax liability related to undistributed earnings of certain foreign subsidiaries which were not previously taxed. Deferred tax assets and liabilities In the year ended December 31, 2017 , we remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21% , by recognizing a tax benefit of $73.7 million , which was principally associated with indefinite-lived intangible assets. Absent this deferred tax liability, we would have been in a net deferred tax asset position that was offset by a valuation allowance at December 31, 2017 . Upon further analysis of certain aspects of the Tax Reform Act and refinement of our calculations during the year ended December 31, 2018 , we determined that no further adjustment was necessary. Global intangible low-taxed income The Tax Reform Act subjects a U.S. shareholder to tax on GILTI earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income , states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. We have elected to account for GILTI in the year the tax is incurred. Income before taxes Income/(loss) before taxes for the years ended December 31, 2019 , 2018 , and 2017 was categorized by jurisdiction as follows: U.S. Non-U.S. Total 2019 $ 13,183 $ 377,240 $ 390,423 2018 $ 68,027 $ 458,348 $ 526,375 2017 $ (11,425 ) $ 413,866 $ 402,441 Provision for/(benefit from) income taxes Provision for/(benefit from) income taxes for the years ended December 31, 2019 , 2018 , and 2017 was categorized by jurisdiction as follows: U.S. Federal Non-U.S. U.S. State Total 2019 Current $ 5,643 $ 73,947 $ 496 $ 80,086 Deferred 9,687 17,339 597 27,623 Total $ 15,330 $ 91,286 $ 1,093 $ 107,709 2018 Current $ 5,700 $ 64,666 $ 1,082 $ 71,448 Deferred (109,663 ) (18,770 ) (15,635 ) (144,068 ) Total $ (103,963 ) $ 45,896 $ (14,553 ) $ (72,620 ) 2017 Current $ — $ 50,601 $ 240 $ 50,841 Deferred (56,956 ) (1,104 ) 1,303 (56,757 ) Total $ (56,956 ) $ 49,497 $ 1,543 $ (5,916 ) Effective tax rate reconciliation The principal reconciling items from income tax computed at the U.S. statutory tax rate for the years ended December 31, 2019 , 2018 , and 2017 were as follows: For the year ended December 31, 2019 2018 2017 Tax computed at statutory rate of 21% in 2019 and 2018, and 35% in 2017 $ 81,989 $ 110,539 $ 140,854 Reserve for tax exposure 20,079 10,775 38,013 Valuation allowances 19,640 (123,426 ) (3,368 ) Foreign tax rate differential (19,107 ) (41,200 ) (111,990 ) Withholding taxes not creditable 9,509 8,734 3,896 Research and development incentives (8,410 ) (19,475 ) (5,922 ) Change in tax laws or rates 5,121 (22,264 ) 3,912 U.S. state taxes, net of federal benefit 863 (11,499 ) 1,087 Unrealized foreign currency exchange losses, net (43 ) 11,346 830 U.S. Tax Reform Act impact — — (73,668 ) Other (1,932 ) 3,850 440 Provision for/(benefit from) income taxes $ 107,709 $ (72,620 ) $ (5,916 ) Valuation allowance impact on tax expense During the year ended December 31, 2018 , we released a substantial portion of our valuation allowance against our deferred tax assets in the U.S. We continue to maintain a valuation allowance against certain of our interest, foreign tax, and state tax credit carryforwards. Refer to the discussion below related to the release of the valuation allowance. U.S. Tax Reform Act Impact As a result of the Tax Reform Act, the U.S. statutory tax rate was lowered from 35% to 21% , effective on January 1, 2018 . We were required to remeasure our U.S. deferred tax assets and liabilities to the new tax rate. For the year ended December 31, 2017 we recognized $73.7 million of income tax benefit for the remeasurement of the deferred tax liabilities associated with indefinite-lived intangible assets that will reverse at the new 21% rate. Absent this deferred tax liability, the U.S. operation was in a net deferred tax asset position that was offset by a full valuation allowance at December 31, 2017 . We reduced our net deferred tax assets excluding the indefinite-lived intangible assets and the corresponding valuation allowance by $120.0 million . Foreign tax rate differential We operate in locations outside the U.S., including Bermuda, Bulgaria, China, Malaysia, the Netherlands, South Korea, and the U.K., that historically have had statutory tax rates different than the U.S. statutory tax rate. This can result in a foreign tax rate differential that may reflect a tax benefit or detriment. This foreign tax rate differential can change from year to year based upon the jurisdictional mix of earnings and changes in current and future enacted tax rates. Our subsidiary in Changzhou, China is currently eligible for a reduced tax rate of 15% , which is effective through 2021 . The impact on current tax expense of the tax holidays and exemptions is included in the foreign tax rate differential line in the reconciliation of the statutory tax rate to effective rate. The remeasurement of the deferred tax assets and liabilities is included in the change in tax laws or rates line. Research and development incentives Certain income of our U.K. subsidiaries is eligible for lower tax rates under the "patent box" regime, resulting in certain of our intellectual property income being taxed at a rate lower than the U.K. statutory tax rate. Certain R&D expenses are eligible for a bonus deduction under China’s R&D super deduction regime. In fiscal year 2018, we substantially completed an assessment of our ability to claim an R&D credit in the U.S. As a result of this assessment, we recognized a tax benefit of $10.0 million . Prior to fiscal year 2018, the deferred tax asset related to these R&D credits would have been offset by the valuation allowance. Withholding taxes not creditable Withholding taxes may apply to intercompany interest, royalty, management fees, and certain payments to third parties. Such taxes are deducted if they cannot be credited against the recipient’s tax liability in its country of residence. Additional consideration also has been given to the withholding taxes associated with unremitted earnings and the recipient's ability to obtain a tax credit for such taxes. Earnings are not considered to be indefinitely reinvested in the jurisdictions in which they were earned. In certain jurisdictions we recognize a deferred tax liability on withholding and other taxes on intercompany payments including dividends. Deferred income tax assets and liabilities The primary components of deferred income tax assets and liabilities as of December 31, 2019 and 2018 were as follows: As of December 31, 2019 2018 Deferred tax assets: Net operating loss, interest expense, and other carryforwards $ 283,094 $ 305,277 Prepaid and accrued expenses 67,143 72,093 Intangible assets 20,457 27,122 Inventories and related reserves 16,712 14,171 Property, plant and equipment 14,749 14,571 Share-based compensation 10,288 11,332 Pension liability and other 7,158 8,741 Unrealized exchange loss 1,959 4,255 Total deferred tax assets 421,560 457,562 Valuation allowance (146,775 ) (157,043 ) Net deferred tax asset 274,785 300,519 Deferred tax liabilities: Intangible assets and goodwill (440,009 ) (440,348 ) Tax on undistributed earnings of subsidiaries (31,636 ) (35,187 ) Property, plant and equipment (13,762 ) (15,795 ) Operating lease right of use assets (12,522 ) — Unrealized exchange gain (6,739 ) (6,912 ) Total deferred tax liabilities (504,668 ) (498,242 ) Net deferred tax liability $ (229,883 ) $ (197,723 ) Valuation allowance and net operating loss carryforwards In measuring our deferred tax assets, we consider all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed for all or some portion of the deferred tax assets. Significant judgment is required in considering the relative impact of the negative and positive evidence, and weight given to each category of evidence is commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, the more positive evidence is necessary, and the more difficult it is to support a conclusion that a valuation allowance is not needed. Additionally, we utilize the "more likely than not" criteria established in FASB ASC Topic 740 to determine whether the future tax benefit from the deferred tax assets should be recognized. As a result, we have established valuation allowances on the deferred tax assets in jurisdictions that have incurred net operating losses and in which it is more likely than not that such losses will not be utilized in the foreseeable future. As of each reporting date, we consider new evidence, both positive and negative, that could impact our view with regard to future realization of deferred tax assets. In the fourth quarter of 2018 , based on reversals of existing taxable differences, projections of future taxable income, and taxable income in the current year, we determined that sufficient positive evidence existed as of December 31, 2018 , to conclude that it is more likely than not the additional deferred taxes of $122.1 million were realizable, and therefore, we reduced the valuation allowance accordingly. One of the provisions of the Tax Reform Act limits the deduction for net interest expense incurred by U.S. corporations to 30% of adjusted taxable income. As a result of this provision, we have determined that certain of our interest carryforwards may be subject to limitation, and as result, determined that it was appropriate to retain the valuation allowance on a significant portion of these carryforwards. For tax purposes, certain goodwill and indefinite-lived intangible assets are generally amortizable over 6 to 20 years. For book purposes, goodwill and indefinite-lived intangible assets are not amortized, but are tested for impairment annually. The tax amortization of goodwill and indefinite-lived intangible assets will result in a taxable temporary difference, which will not reverse unless the related book goodwill or indefinite-lived intangible asset is impaired or written off. This liability may not be used to support deductible temporary differences, such as net operating loss carryforwards, which may expire within a definite period. The total valuation allowance for the years ended December 31, 2019 and 2018 decreased $10.3 million and $120.3 million , respectively. Subsequently reported tax benefits relating to the valuation allowance for deferred tax assets as of December 31, 2019 will be allocated to income tax benefit recognized in the consolidated statements of operations. As of December 31, 2019 , we have U.S. federal net operating loss carryforwards of $472.0 million and suspended interest expense carryforwards of $511.4 million . Substantially all of our U.S. federal net operating loss carryforwards will expire from 2027 to 2037 . Our state net operating loss carryforwards will expire from 2020 to 2037 . Our interest carryovers have an unlimited life. We also have non-U.S. net operating loss carryforwards of $221.9 million , which will begin to expire in 2020 . Unrecognized tax benefits A reconciliation of the amount of unrecognized tax benefits is as follows: For the year ended December 31, 2019 2018 2017 Balance at beginning of year $ 89,609 $ 59,884 $ 45,898 Increases related to current year tax positions 17,378 15,676 14,585 Increases related to prior year tax positions 15,356 14,609 7,968 Decreases related to settlements with tax authorities (3,515 ) — (7,211 ) Decreases related to prior year tax positions (1,773 ) (1,144 ) — Increases related to business combinations 450 1,000 — Decreases related to lapse of applicable statute of limitations (87 ) — (1,356 ) Increases/(decreases) related to foreign currency exchange rate 173 (416 ) — Balance at end of year $ 117,591 $ 89,609 $ 59,884 We recognize interest and penalties related to unrecognized tax benefits in the consolidated statements of operations and the consolidated balance sheets. The table that follows presents the expense/(income) related to such interest and penalties recognized in the consolidated statements of operations during the years ended December 31, 2019 , 2018 , and 2017 , and the amount of interest and penalties recorded on the consolidated balance sheets as of December 31, 2019 and 2018 : Statements of Operations Balance Sheets For the year ended December 31, As of December 31, (In millions) 2019 2018 2017 2019 2018 Interest $ 0.9 $ (0.2 ) $ 0.2 $ 1.3 $ 0.4 Penalties $ (0.1 ) $ (0.2 ) $ (0.1 ) $ 0.3 $ 0.4 At December 31, 2019 , we anticipate that the liability for unrecognized tax benefits could decrease by up to $6.5 million within the next twelve months due to the expiration of certain statutes of limitation or the settlement of examinations or issues with tax authorities. The amount of unrecognized tax benefits as of December 31, 2019 that if recognized, would impact our effective tax rate is $67.8 million . Our major tax jurisdictions include Belgium, Bulgaria, China, France, Germany, Japan, Malaysia, Mexico, the Netherlands, South Korea, the U.K., and the U.S. These jurisdictions generally remain open to examination by the relevant tax authority for the tax years 2006 through 2019 .

Net Income Per Share	Net Income per Share Basic and diluted net income per share are calculated by dividing net income by the number of basic and diluted weighted-average ordinary shares outstanding during the period. For the years ended December 31, 2019 , 2018 , and 2017 , the weighted-average ordinary shares outstanding used to calculate basic and diluted net income per share were as follows: For the year ended December 31, (In thousands) 2019 2018 2017 Basic weighted-average ordinary shares outstanding 160,946 168,570 171,165 Dilutive effect of stock options 600 822 616 Dilutive effect of unvested restricted securities 422 467 388 Diluted weighted-average ordinary shares outstanding 161,968 169,859 172,169 Net income and net income per share are presented in the consolidated statements of operations. Certain potential ordinary shares were excluded from our calculation of diluted weighted-average ordinary shares outstanding because either they would have had an anti-dilutive effect on net income per share or they related to equity awards that were contingently issuable for which the contingency had not been satisfied. Refer to Note 4, "Share-Based Payment Plans," for additional information related to our equity awards. These potential ordinary shares are as follows: For the year ended December 31, (In thousands) 2019 2018 2017 Anti-dilutive shares excluded 1,170 930 1,410 Contingently issuable shares excluded 641 687 871

Goodwill attributed to acquisitions reflects our allocation of purchase price to the estimated fair value of certain assets acquired and liabilities assumed, and has been assigned to our segments based on a methodology using anticipated future earnings of the components of business. Goodwill attributed to the divestiture of the Valves Business is based on the relative fair value of the Valves Business to the Performance Sensing reporting unit. Refer to Note 17, "Acquisitions and Divestitures," for additional information related to our acquisition and divestiture transactions. We own the Klixon ® and Airpax ® tradenames, which are indefinite-lived intangible assets, as they have each been in continuous use for over 65 years , and we have no plans to discontinue using them. We have recorded $59.1 million and $9.4 million , respectively, on the consolidated balance sheets related to these tradenames. We evaluated our goodwill and other indefinite-lived intangible assets for impairment as of October 1, 2019 using quantitative analyses. Refer to Note 2, "Significant Accounting Policies," for additional information related to the methodology used. Based on these analyses, we have determined that as of October 1, 2019 the fair value of each of our reporting units and indefinite-lived intangible assets exceeded their carrying values.

Retirement Benefits [Abstract]
Pension and Other Post-Retirement Benefits	Pension and Other Post-Retirement Benefits We provide various pension and other post-retirement plans for current and former employees, including defined benefit, defined contribution, and retiree healthcare benefit plans. Refer to Note 2, "Significant Accounting Policies," for a detailed discussion of the accounting policies related to our pension and other post-retirement benefit plans. U.S. Benefit Plans The principal retirement plans in the U.S. include a qualified defined benefit pension plan and a defined contribution plan. In addition, we provide post-retirement medical coverage and non-qualified benefits to certain employees. Defined Benefit Pension Plans The benefits under the qualified defined benefit pension plan are determined using a formula based upon years of service and the highest five consecutive years of compensation. TI closed the qualified defined benefit pension plan to participants hired after November 1997. In addition, participants eligible to retire under the TI plan as of April 26, 2006 were given the option of continuing to participate in the qualified defined benefit pension plan or retiring under the qualified defined benefit pension plan and thereafter participating in an enhanced defined contribution plan. We intend to contribute amounts to the qualified defined benefit pension plan in order to meet the minimum funding requirements of federal laws and regulations, plus such additional amounts as we deem appropriate. During the year ended December 31, 2019 , we contributed $3.3 million to the qualified defined benefit plan. We do not expect to contribute to the qualified defined benefit pension plan in fiscal year 2020 . We also sponsor a non-qualified defined benefit pension plan, which is closed to new participants and is unfunded. Effective January 31, 2012 , we froze the defined benefit pension plans and eliminated future benefit accruals. Defined Contribution Plans We have one defined contribution plan for U.S. employees, which provides for an employer matching contribution of up to 4% of the employee's annual eligible earnings. The aggregate expense related to the defined contribution plan was $5.5 million , $5.7 million , and $5.9 million for the years ended December 31, 2019 , 2018 , and 2017 , respectively. Retiree Healthcare Benefit Plan We offer access to group medical coverage during retirement to some of our U.S. employees. We make contributions toward the cost of those retiree medical benefits for certain retirees. The contribution rates are based upon varying factors, the most important of which are an employee’s date of hire, date of retirement, years of service, and eligibility for Medicare benefits. The balance of the cost is borne by the participants in the plan. For the year ended December 31, 2019 , we did not and do not expect to, receive any amount of Medicare Part D Federal subsidy. Our projected benefit obligation as of December 31, 2019 and 2018 did not include an assumption for a Federal subsidy. Non-U.S. Benefit Plans Retirement coverage for non-U.S. employees is provided through separate defined benefit and defined contribution plans. Retirement benefits are generally based on an employee’s years of service and compensation. Funding requirements are determined on an individual country and plan basis and are subject to local country practices and market circumstances. We do not expect to contribute to the non-U.S. defined benefit plans during 2020 . Impact on Financial Statements The components of net periodic benefit cost/(credit) associated with our defined benefit and retiree healthcare plans for the years ended December 31, 2019 , 2018 , and 2017 were as follows: For the year ended December 31, 2019 2018 2017 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Defined Benefit Retiree Healthcare Defined Benefit Defined Benefit Retiree Healthcare Defined Benefit Defined Benefit Retiree Healthcare Defined Benefit Service cost $ — $ 7 $ 2,836 $ — $ 50 $ 3,122 $ — $ 74 $ 2,582 Interest cost 1,483 203 1,344 1,473 272 1,310 1,604 325 1,053 Expected return on plan assets (1,694 ) — (702 ) (1,710 ) — (929 ) (2,151 ) — (905 ) Amortization of net loss 946 — 766 1,080 5 407 1,149 54 287 Amortization of net prior service (credit)/cost — (1,306 ) 9 — (1,728 ) 6 — (1,335 ) (4 ) Loss on settlement 565 — 1,572 1,047 — 1,461 3,225 — 100 Loss on curtailment — — — — — 891 — — — Net periodic benefit cost/(credit) $ 1,300 $ (1,096 ) $ 5,825 $ 1,890 $ (1,401 ) $ 6,268 $ 3,827 $ (882 ) $ 3,113 The following table outlines the rollforward of the benefit obligation and plan assets for the defined benefit and retiree healthcare benefit plans for the years ended December 31, 2019 and 2018 : For the year ended December 31, 2019 2018 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Defined Benefit Retiree Healthcare Defined Benefit Defined Benefit Retiree Healthcare Defined Benefit Change in benefit obligation: Beginning balance $ 45,169 $ 6,017 $ 65,691 $ 48,615 $ 9,692 $ 67,413 Service cost — 7 2,836 — 50 3,122 Interest cost 1,483 203 1,344 1,473 272 1,310 Plan participants’ contributions — 474 31 — 475 60 Plan amendment — — — — (3,243 ) — Actuarial loss/(gain) 1,711 (92 ) 9,344 (519 ) (124 ) 2,777 Curtailments — — — — — 931 Benefits paid (2,815 ) (1,021 ) (5,235 ) (4,400 ) (1,105 ) (6,262 ) Divestiture — — — — — (3,310 ) Foreign currency remeasurement — — 161 — — (350 ) Ending balance $ 45,548 $ 5,588 $ 74,172 $ 45,169 $ 6,017 $ 65,691 Change in plan assets: Beginning balance $ 39,875 $ — $ 39,868 $ 41,101 $ — $ 41,222 Actual return on plan assets 4,484 — 4,125 (811 ) — (1,308 ) Employer contributions 3,326 547 4,889 3,985 630 5,992 Plan participants’ contributions — 474 31 — 475 60 Benefits paid (2,815 ) (1,021 ) (5,235 ) (4,400 ) (1,105 ) (6,262 ) Foreign currency remeasurement — — 228 — — 164 Ending balance $ 44,870 $ — $ 43,906 $ 39,875 $ — $ 39,868 Funded status at end of year $ (678 ) $ (5,588 ) $ (30,266 ) $ (5,294 ) $ (6,017 ) $ (25,823 ) Accumulated benefit obligation at end of year $ 45,548 NA $ 65,633 $ 45,169 NA $ 59,948 The following table outlines the funded status amounts recognized in the consolidated balance sheets as of December 31, 2019 and 2018 : As of December 31, 2019 2018 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Defined Benefit Retiree Healthcare Defined Benefit Defined Benefit Retiree Healthcare Defined Benefit Noncurrent assets $ 2,788 $ — $ — $ — $ — $ — Current liabilities (952 ) (717 ) (1,551 ) (595 ) (1,116 ) (1,465 ) Noncurrent liabilities (2,514 ) (4,871 ) (28,715 ) (4,699 ) (4,901 ) (24,358 ) Funded status $ (678 ) $ (5,588 ) $ (30,266 ) $ (5,294 ) $ (6,017 ) $ (25,823 ) Balances recognized within accumulated other comprehensive loss that have not been recognized as components of net periodic benefit cost, net of tax, as of December 31, 2019 , 2018 , and 2017 are as follows: As of December 31, 2019 2018 2017 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Defined Benefit Retiree Healthcare Defined Benefit Defined Benefit Retiree Healthcare Defined Benefit Defined Benefit Retiree Healthcare Defined Benefit Net prior service cost/(credit) $ — $ 306 $ (16 ) $ — $ (692 ) $ (10 ) $ — $ 823 $ (220 ) Net loss $ 18,780 $ 809 $ 17,151 $ 20,759 $ 880 $ 14,425 $ 20,884 $ 1,009 $ 12,489 We expect to amortize a loss of $1.4 million from accumulated other comprehensive loss to net periodic benefit cost during fiscal year 2020 .

Information about the assets for each of these plans is detailed below. Refer to Note 18, "Fair Value Measures," for additional information related to the levels of the fair value hierarchy in accordance with FASB ASC Topic 820. U.S. Plan Assets Our target asset allocation for the U.S. defined benefit plan is 83% fixed income and 17% equity securities. To arrive at the targeted asset allocation, we and our investment adviser reviewed market opportunities using historical data, as well as the actuarial valuation for the plan, to ensure that the levels of acceptable return and risk are well-defined and monitored. The following table presents information about the plan’s target and actual asset allocation, as of December 31, 2019 : Target Allocation Actual Allocation as of December 31, 2019 U.S. large cap equity 7% 5% U.S. small / mid cap equity 2% 1% Globally managed volatility fund 3% 2% International (non-U.S.) equity 4% 3% Fixed income (U.S. investment grade) (1) 68% 42% High-yield fixed income 2% 1% International (non-U.S.) fixed income 1% 1% Money market funds (1) 13% 45% __________________________________________ (1) As of December 31, 2019, our holdings in the Money market funds exceed the target allocation as we prepare to make payments resulting from the voluntary retirement incentive program. Refer to Note 5, "Restructuring and Other Charges, Net" for additional information about the voluntary retirement incentive program. The portfolio is monitored for automatic rebalancing on a monthly basis. The following table presents information about the plan assets measured at fair value as of December 31, 2019 and 2018 : As of December 31, 2019 2018 U.S. large cap equity $ 2,221 $ 2,960 U.S. small / mid cap equity 637 833 Global managed volatility fund 849 1,214 International (non-U.S.) equity 1,195 1,493 Total equity mutual funds 4,902 6,500 Fixed income (U.S. investment grade) 18,830 26,884 High-yield fixed income 561 792 International (non-U.S.) fixed income 264 402 Total fixed income mutual funds 19,655 28,078 Money market funds 20,313 5,297 Total plan assets $ 44,870 $ 39,875 All fair value measures presented above are categorized in Level 1 of the fair value hierarchy. Investments in mutual funds are based on the publicly-quoted final net asset values on the last business day of the year. Permitted asset classes include U.S. and non-U.S. equity, U.S. and non-U.S. fixed income, cash, and cash equivalents. Fixed income includes both investment grade and non-investment grade. Permitted investment vehicles include mutual funds, individual securities, derivatives, and long-duration fixed income securities. While investments in individual securities, derivatives, long-duration fixed income securities, cash, and cash equivalents are permitted, the plan did not hold these types of investments as of December 31, 2019 and 2018 . Prohibited investments include direct investments in real estate, commodities, unregistered securities, uncovered options, currency exchange contracts, and natural resources (such as timber, oil, and gas). Japan Plan Assets The target asset allocation of the Japan defined benefit plan is 50% fixed income securities and 50% equity securities, cash, and cash equivalents, with allowance for a 40% deviation in either direction. We, along with the trustee of the plan's assets, minimize investment risk by thoroughly assessing potential investments based on indicators of historical returns and current credit ratings. Additionally, investments are diversified by type and geography. The following table presents information about the plan’s target asset allocation, as well as the actual allocation, as of December 31, 2019 : Target Allocation Actual Allocation as of December 31, 2019 Fixed income securities, cash, and cash equivalents 10%-90% 65% Equity securities 10%-90% 35% The following table presents information about the plan assets measured at fair value as of December 31, 2019 and 2018 : As of December 31, 2019 2018 U.S. equity $ 2,413 $ 2,212 International (non-U.S.) equity 6,343 5,158 Total equity securities 8,756 7,370 U.S. fixed income 3,835 3,345 International (non-U.S.) fixed income 9,716 8,811 Total fixed income securities 13,551 12,156 Cash and cash equivalents 9,726 10,339 Total plan assets $ 32,033 $ 29,865 All fair value measures presented above are categorized in Level 1 of the fair value hierarchy, with the exception of U.S. fixed income securities of $0.3 million and $0.3 million as of December 31, 2019 and 2018 , respectively, which are categorized as Level 2. The fair values of equity and fixed income securities are based on publicly-quoted closing stock and bond values on the last business day of the year. Permitted asset classes include equity securities that are traded on the official stock exchange(s) of the respective countries, fixed income securities with certain credit ratings, cash, and cash equivalents. The Netherlands Plan Assets The assets of the Netherlands defined benefit plan are insurance policies. The contributions we make to the plan are used to purchase insurance policies that provide for specific benefit payments to plan participants. The benefit formula is determined independently by us. Upon retirement of an individual plan participant, the insurance contracts purchased are converted to provide specific benefits for the participant. The contributions paid by us are commingled with contributions paid to the insurance provider by other employers for investment purposes and to reduce plan administration costs. However, this defined benefit plan is not considered a multi-employer plan. The following table presents information about the plan assets measured at fair value as of December 31, 2019 and 2018 : As of December 31, 2019 2018 Insurance policies $ 10,472 $ 8,897 All fair value measures presented above are categorized in Level 3 of the fair value hierarchy. The following table presents a rollforward of these assets for the years ended December 31, 2019 and 2018 : Insurance Policies Balance as of December 31, 2017 $ 9,059 Actual return on plan assets still held at reporting date 177 Purchases, sales, settlements, and exchange rate changes (339 ) Balance as of December 31, 2018 8,897 Actual return on plan assets still held at reporting date 1,821 Purchases, sales, settlements, and exchange rate changes (246 ) Balance as of December 31, 2019 $ 10,472 The fair values of the insurance contracts are measured based on the future benefit payments that would be made by the insurance company to vested plan participants if we were to switch to another insurance company without actually surrendering our policy. In this case, the insurance company would guarantee to pay the vested benefits at retirement accrued under the plan based on current salaries and service to date (i.e., with no allowance for future salary increases or pension increases). The cash flows of the future benefit payments are discounted using the same discount rate that is applied to value the related defined benefit plan liability. Belgium Plan Assets The assets of the Belgium defined benefit plan are insurance policies. As of December 31, 2019 and 2018 the fair values of these assets were $1.3 million and $1.1 million

On March 27, 2019 certain indirect, wholly-owned subsidiaries of Sensata plc, including Sensata Technologies B.V. ("STBV"), entered into the ninth amendment (the "Ninth Amendment") of the Credit Agreement. Among other changes to the Credit Agreement, the Ninth Amendment (i) extended the maturity date of the Revolving Credit Facility to March 27, 2024 ; (ii) added pounds sterling as an available currency for revolving credit loans and letters of credit under the Revolving Credit Facility; (iii) lowered the interest rate margins related to the Revolving Credit Facility (depending on our senior secured net leverage ratio); (iv) lowered our letter of credit fees (depending on our senior secured net leverage ratio); (v) reduced our revolving credit commitment fees (depending on our senior secured net leverage ratio); and (vi) modified the senior secured net leverage ratio financial covenant to increase the Revolving Credit Facility utilization threshold above which such financial covenant is tested from 10% to 20% and eliminated the requirement that such ratio be tested (regardless of utilization) for purposes of satisfying the conditions to any borrowing or other utilization under the Revolving Credit Facility. On June 13, 2019 , our subsidiaries that were at the time borrowers under the Credit Agreement entered into an amendment to the Credit Agreement with the administrative agent to correct certain technical and immaterial errors in the Credit Agreement. On September 20, 2019 certain of our subsidiaries, including STBV and its indirect, wholly-owned subsidiary, Sensata Technologies Inc. ("STI"), entered into the tenth amendment of the Credit Agreement (the "Tenth Amendment"). Under the terms of the Tenth Amendment, among other changes to the Credit Agreement, (i) the final maturity date of the Term Loan was extended to September 20, 2026 ; (ii) STI became the sole borrower under the Credit Agreement and assumed substantially all of the obligations of STBV and Sensata Technologies Finance Company, LLC ("STFC") thereunder; (iii) STBV became a guarantor of STI’s obligations under the Credit Agreement, and STFC ceased to be a guarantor with respect to the Credit Agreement; (iv) certain subsidiaries of STBV that previously guaranteed STBV’s and/or STFC’s obligations under the Credit Agreement (the “Released Guarantors”) were released from their guarantees under the Credit Agreement, subject to the satisfaction of certain tests (the “Guarantees Release”); (v) the permission to incur incremental additional indebtedness under the Credit Agreement was increased; and (vi) certain of the operational and restrictive covenants and other terms and conditions of the Senior Secured Credit Facilities to which STBV and its restricted subsidiaries are subject were modified to provide us with increased flexibility and permissions thereunder (including permission, subject to no default or event of default, to make restricted payments (including dividends) in an amount equal to $50.0 million annually, which can be increased to an unlimited amount subject to compliance with a specified senior secured net leverage ratio). All obligations under the Senior Secured Credit Facilities are unconditionally guaranteed by certain of our subsidiaries and secured by substantially all present and future property and assets of STBV and its guarantor subsidiaries. The Credit Agreement provides that, if our senior secured net leverage ratio exceeds a specified level, we are required to use a portion of our excess cash flow, as defined in the Credit Agreement, generated by operating, investing, or financing activities to prepay the outstanding borrowings under the Senior Secured Credit Facilities. The Credit Agreement also requires mandatory prepayments of the outstanding borrowings under the Senior Secured Credit Facilities upon certain asset dispositions and casualty events, in each case subject to certain reinvestment rights, and the incurrence of certain indebtedness (excluding any permitted indebtedness). These provisions were not triggered during the year ended December 31, 2019 . Term Loan The principal amount of the Term Loan amortizes in equal quarterly installments in an aggregate annual amount equal to 1.0% of the aggregate principal amount of the Term Loan upon completion of the Tenth Amendment, with the balance due at maturity. In accordance with the terms of the Credit Agreement, the Term Loan may, at our option, be maintained from time to time as a Base Rate loan or a Eurodollar Rate loan (each as defined in the Credit Agreement), with each representing a different determination of interest rates. The interest rate margins for the Term Loan are fixed at, and as of December 31, 2019 were, 0.75% and 1.75% for Base Rate loans and Eurodollar Rate loans, respectively, subject to floors of 1.00% and 0.00% for Base Rate loans and Eurodollar Rate loans, respectively. As of December 31, 2019 , we maintained the Term Loan as a Eurodollar Rate loan, which accrued interest at 3.59% . Revolving Credit Facility In accordance with the terms of the Credit Agreement, borrowings under the Revolving Credit Facility may, at our option, be maintained from time to time as Base Rate loans, Eurodollar Rate loans, or EURIBOR loans (each as defined in the Credit Agreement), with each representing a different determination of interest rates. The interest rate margins and letter of credit fees under the Revolving Credit Facility are as follows (each depending on our senior secured net leverage ratio): (i) the interest rate margin for Eurodollar Rate loans ranges from 1.00% to 1.50% ; (ii) the interest rate margin for Base Rate loans ranges from 0.00% to 0.50% ; and (iii) the letter of credit fees range from 0.875% to 1.375% . We are required to pay to our revolving credit lenders, on a quarterly basis, a commitment fee on the unused portion of the Revolving Credit Facility. The commitment fee ranges from 0.125% to 0.25% , depending on our senior secured net leverage ratios. As of December 31, 2019 , there was $416.1 million available under the Revolving Credit Facility, net of $3.9 million of obligations in respect of outstanding letters of credit issued thereunder. Outstanding letters of credit are issued primarily for the benefit of certain operating activities. As of December 31, 2019 , no amounts had been drawn against these outstanding letters of credit. Availability under the Revolving Credit Facility may be borrowed, repaid, and re-borrowed to fund our working capital needs and for other general corporate purposes. Senior Notes We have various tranches of senior notes outstanding. These consisted of $500.0 million in aggregate principal amount of 4.875% senior notes due 2023 issued by STBV (the " 4.875% Senior Notes"), $400.0 million in aggregate principal amount of 5.625% senior notes due 2024 issued by STBV (the " 5.625% Senior Notes"), $700.0 million in aggregate principal amount of 5.0% senior notes due 2025 issued by STBV (the " 5.0% Senior Notes"), $750.0 million in aggregate principal amount of 6.25% senior notes due 2026 (the " 6.25% Senior Notes") issued by our subsidiary Sensata Technologies UK Financing Co. plc ("STUK"), and $450.0 million in aggregate principal amount of 4.375% senior notes due 2030 issued by STI (the " 4.375% Senior Notes" and together with the other senior notes referenced above, the "Senior Notes"). 4.375% Senior Notes On September 20, 2019 , concurrently with the entry into the Tenth Amendment, we completed the issuance and sale of the 4.375% Senior Notes. The proceeds of the issuance of the 4.375% Senior Notes were used to partially repay the Term Loan. The 4.375% Senior Notes were issued under an indenture dated as of September 20, 2019 among STI, as issuer, The Bank of New York Mellon, as trustee, and our guarantor subsidiaries named therein. The 4.375% Senior Notes were offered at par, and interest is payable semi-annually on February 15 and August 15 of each year, commencing on February 15, 2020 . 4.875% Senior Notes In April 2013 we completed the issuance and sale of the 4.875% Senior Notes, which were issued under an indenture dated as of April 17, 2013 among STBV, as issuer, The Bank of New York Mellon, as trustee, and the guarantors named therein. The 4.875% Senior Notes were offered at par. Interest on the 4.875% Senior Notes is payable semi-annually on April 15 and October 15 of each year. 5.625% Senior Notes In October 2014 we completed the issuance and sale of the 5.625% Senior Notes, which were issued under an indenture dated as of October 14, 2014, among STBV, as issuer, The Bank of New York Mellon, as trustee, and the guarantors named therein. The 5.625% Senior Notes were offered at par. Interest on the 5.625% Senior Notes is payable semi-annually on May 1 and November 1 of each year. 5.0% Senior Notes In March 2015 we completed the issuance and sale of the 5.0% Senior Notes, which were issued under an indenture dated as of March 26, 2015, among STBV, as issuer, The Bank of New York Mellon, as trustee, and the guarantors named therein. The 5.0% Senior Notes were offered at par. Interest on the 5.0% Senior Notes is payable semi-annually on April 1 and October 1 of each year. 6.25% Senior Notes In November 2015, we completed the issuance and sale of the 6.25% Senior Notes, which were issued under an indenture dated as of November 27, 2015 (the " 6.25% Senior Notes Indenture" and, together with the indentures under which the other Senior Notes were issued, the "Senior Notes Indentures"), among STUK, as issuer, The Bank of New York Mellon, as trustee, and the guarantors named therein. The 6.25% Senior Notes were offered at par. Interest on the 6.25% Senior Notes is payable semi-annually on February 15 and August 15 of each year. Redemption Except as described below with respect to the 4.375% Senior Notes and the 6.25% Senior Notes, at any time, and from time to time, we may optionally redeem the Senior Notes, in whole or in part, at a price equal to 100% of the principal amount of the notes redeemed, plus accrued and unpaid interest, if any, up to, but excluding, the date of redemption, plus a "make-whole premium" set forth in the relevant Senior Notes Indenture. The "make-whole" premium will not be payable with respect to any such redemption of the 4.375% Senior Notes on or after November 15, 2029. The "make-whole" premium will not be payable with respect to any such redemption of the 6.25% Senior Notes on or after February 15, 2021; on or after such date, we may optionally redeem the 6.25% Senior Notes, in whole or in part, at the following prices (plus accrued and unpaid interest to the date of redemption, if any) during the applicable period: Period beginning February 15, Price 2021 103.125 % 2022 102.083 % 2023 101.042 % 2024 and thereafter 100.000 % Upon the occurrence of certain specific kinds of changes in control, the issuers of the Senior Notes will be required to offer to repurchase the notes at 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase. If changes in certain tax laws or treaties, or any change in the official application, administration, or interpretation thereof, of any relevant taxing jurisdiction become effective that would impose withholding taxes or other deductions on the payments of any of the Senior Notes or the guarantees thereof, we may, at our option, redeem the relevant Senior Notes in whole but not in part, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, premium, if any, and all additional amounts (as described in the relevant Senior Notes Indenture), if any, then due and which will become due on the date of redemption. Guarantees The obligations of the issuers of the Senior Notes are guaranteed by STBV and all of its subsidiaries (excluding the company that is the issuer of the relevant Senior Notes) that guarantee the obligations of STI under Credit Agreement (after giving effect to the Guarantees Release pursuant to the Tenth Amendment). The Released Guarantors are not guarantors of the 4.375% Senior Notes, and upon consummation of the Tenth Amendment, the guarantees of the Released Guarantors with respect to the other Senior Notes were released. Events of Default The Senior Notes Indentures provide for events of default that include, among others, nonpayment of principal or interest when due, breach of covenants or other provisions in the relevant Senior Notes Indenture, defaults in payment of certain other indebtedness, certain events of bankruptcy or insolvency, failure to pay certain judgments, and the cessation of the full force and effect of the guarantees of significant subsidiaries. Generally, if an event of default occurs, the trustee or the holders of at least 25% in principal amount of the then outstanding Senior Notes issued under the relevant Senior Notes Indenture may declare the principal of, and accrued but unpaid interest on, all of the relevant Senior Notes to be due and payable immediately. All provisions regarding remedies in an event of default are subject to the relevant Senior Notes Indenture. Restrictions and Covenants As of December 31, 2019 , STBV and all of its subsidiaries were subject to certain restrictive covenants under the Credit Agreement and the Senior Notes Indentures. Under certain circumstances, STBV is permitted to designate a subsidiary as "unrestricted" for purposes of the Credit Agreement, in which case the restrictive covenants thereunder will not apply to that subsidiary; the Senior Notes Indentures do not contain such a permission. STBV has not designated any subsidiaries as unrestricted. The net assets of STBV subject to these restrictions totaled $2,555.0 million at December 31, 2019 . Credit Agreement The Credit Agreement contains non-financial restrictive covenants (subject to important exceptions and qualifications set forth in the Credit Agreement) that limit our ability to, among other things: • incur indebtedness or liens, prepay subordinated debt, or amend the terms of our subordinated debt; • make loans and investments (including acquisitions) or sell assets; • change our business or accounting policies, merge, consolidate, dissolve or liquidate, or amend the terms of our organizational documents; • enter into affiliate transactions; • pay dividends and make other restricted payments; or • enter into certain burdensome contractual obligations. In addition, under the Credit Agreement, STBV and its subsidiaries are required to maintain a senior secured net leverage ratio not to exceed 5.0 : 1.0 at the conclusion of certain periods when outstanding loans and letters of credit that are not cash collateralized for the full face amount thereof exceed 20% of the commitments under the Revolving Credit Facility. Senior Notes Indentures The Senior Notes Indentures contain restrictive covenants (subject to important exceptions and qualifications set forth in the Senior Notes Indentures) that limit the ability of STBV and its subsidiaries to, among other things: • incur liens; • incur or guarantee indebtedness without guaranteeing the Senior Notes; • engage in sale and leaseback transactions; or • effect mergers or consolidations, or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of the assets of STBV and its subsidiaries. Certain of these covenants will be suspended if the Senior Notes are assigned an investment grade rating by Standard & Poor's Rating Services or Moody's Investors Service, Inc. and provided no default has occurred and is continuing at such time. The suspended covenants will be reinstated if the Senior Notes are no longer assigned an investment grade rating by either rating agency or an event of default has occurred and is continuing at such time. As of December 31, 2019 , none of the Senior Notes were assigned an investment grade rating by either rating agency. Restrictions on Payment of Dividends STBV's subsidiaries are generally not restricted in their ability to pay dividends or otherwise distribute funds to STBV, except for restrictions imposed under applicable corporate law. STBV, however, is limited in its ability to pay dividends or otherwise make distributions to its immediate parent company and, ultimately, to Sensata plc, under the Credit Agreement. Specifically, the Credit Agreement prohibits STBV from paying dividends or making distributions to its parent companies except for purposes that include, but are not limited to, the following: • customary and reasonable operating expenses, legal and accounting fees and expenses, and overhead of such parent companies incurred in the ordinary course of business, provided that such amounts, in the aggregate, do not exceed $20.0 million in any fiscal year; • dividends and other distributions in an aggregate amount not to exceed $200.0 million plus certain amounts, including the retained portion of excess cash flow, but only insofar as no default or event of default exists and the senior secured net leverage ratio is less than 2.0 : 1.0 calculated on a pro forma basis; • so long as no default or an event of default exists, dividends and other distributions in an aggregate amount not to exceed $50.0 million in any calendar year (with the unused portion in any year being carried over to succeeding years) plus unlimited additional amounts but only insofar as the senior secured net leverage ratio is less than 2.5:1.0 calculated on a pro forma basis; and • other dividends and other distributions in an aggregate amount not to exceed $150.0 million , so long as no default or event of default exists. The Senior Notes Indentures generally allow STBV to pay dividends and make other distributions to its parent companies. Compliance with Financial and Non-Financial Covenants We were in compliance with all of the financial and non–financial covenants and default provisions associated with our indebtedness as of December 31, 2019 and for the fiscal year then ended. Accounting for Debt Financing Transactions During the year ended December 31, 2019 , in connection with the entry into the Ninth Amendment, we incurred $2.4 million of creditor fees and related third-party costs, which were recorded as an adjustment to the carrying amount of long-term debt. During the year ended December 31, 2019 , in connection with of the issuance of the 4.375% Senior Notes, the entry into the Tenth Amendment, and the subsequent partial repayment of the Term Loan, we recognized a loss of $4.4 million , presented in the other, net line of our consolidated statement of operations, as well as $5.0 million of deferred financing costs, which are presented as a reduction of long-term debt on our consolidated balance sheets. During the year ended December 31, 2018 , in connection with the Merger, we paid $5.8 million of creditor fees and related third-party costs in order to obtain consents to the transaction from our existing lenders. As a result, and based on application of the provisions in FASB ASC Subtopic 470-50, we recognized a $3.5 million adjustment to the carrying value of long-term debt, net and a $2.4 million loss in other, net. During the year ended December 31, 2017, we recognized a $0.2 million adjustment to the carrying value of long-term debt, net and a $2.7 million loss in other, net, based on application of the provisions in FASB ASC Subtopic 470-50. Refer to Note 2, "Significant Accounting Policies," for additional information related to our accounting policies regarding debt financing transactions. Finance Lease and Other Financing Obligations Refer to Note 21, "Leases," for additional information related to our finance leases. Debt Maturities The aggregate principal amount of each tranche of our Senior Notes is due in full at its maturity date. The Term Loan must be repaid in full on or prior to its final maturity date. Loans made pursuant to the Revolving Credit Facility must be repaid in full at its maturity date and can be repaid prior to then at par. All letters of credit issued thereunder will terminate at the final maturity of the Revolving Credit Facility unless cash collateralized prior to such time. The following table presents the remaining mandatory principal repayments of long-term debt, excluding finance lease payments, other financing obligations, and discretionary repurchases of debt, in each of the years ended December 31, 2020 through 2024 and thereafter. For the year ended December 31, Aggregate Maturities 2020 $ 4,630 2021 4,630 2022 4,630 2023 504,630 2024 404,630 Thereafter 2,337,575 Total long-term debt principal payments $ 3,260,725

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended
	Dec. 31, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable purchase agreements exist with various suppliers, primarily for services such as information technology support. The terms of these agreements are fixed and determinable. As of December 31, 2019 , we had the following purchase commitments: For the year ending December 31, 2020 $ 26,588 2021 19,726 2022 9,721 2023 5,060 2024 132 2025 and thereafter 272 Total purchase commitments $ 61,499 Off-Balance Sheet Arrangements From time to time, we execute contracts that require us to indemnify the other parties to the contracts. These indemnification obligations generally arise in two contexts. First, in connection with certain transactions, such as the divestiture of a business or the issuance of debt or equity securities, the agreement typically contains standard provisions requiring us to indemnify the purchaser against breaches by us of representations and warranties contained in the agreement. These indemnities are generally subject to time and liability limitations. Second, we enter into agreements in the ordinary course of business, such as customer contracts, that might contain indemnification provisions relating to product quality, intellectual property infringement, governmental regulations and employment related matters, and other typical indemnities. In certain cases, indemnification obligations arise by law. We believe that our indemnification obligations are consistent with other companies in the markets in which we compete. Performance under any of these indemnification obligations would generally be triggered by a breach of the terms of the contract or by a third-party claim. Historically, we have experienced only immaterial and irregular losses associated with these indemnifications. Consequently, any future liabilities brought about by these indemnifications cannot reasonably be estimated or accrued. Indemnifications Provided As Part of Contracts and Agreements We are party to the following types of agreements pursuant to which we may be obligated to indemnify a third party with respect to certain matters. Officers and Directors: Our articles of association provide for indemnification of directors and officers by us to the fullest extent permitted by applicable law, as it now exists or may hereinafter be amended (but, in the case of an amendment, only to the extent such amendment permits broader indemnification rights than permitted prior thereto), against any and all liabilities, including all expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit, or proceeding, provided he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful or outside of his or her mandate. The articles do not provide a limit to the maximum future payments, if any, under the indemnification. No indemnification is provided for in respect of any claim, issue, or matter as to which such person has been adjudged to be liable for gross negligence or willful misconduct in the performance of his or her duty on our behalf. In addition, we have a liability insurance policy that insures directors and officers against the cost of defense, settlement, or payment of claims and judgments under some circumstances. Certain indemnification payments may not be covered under our directors’ and officers’ insurance coverage. Initial Purchasers of Senior Notes : Pursuant to the terms of the purchase agreements entered into in connection with our private placement senior note offerings, we are obligated to indemnify the initial purchasers of the Senior Notes against certain liabilities caused by any untrue statement or alleged untrue statement of a material fact in various documents relied upon by such initial purchasers, or to contribute to payments the initial purchasers may be required to make in respect thereof. The purchase agreements do not provide a limit to the maximum future payments, if any, under these indemnifications. Intellectual Property and Product Liability Indemnification: We routinely sell products with a limited intellectual property and product liability indemnification included in the terms of sale. Historically, we have had only immaterial and irregular losses associated with these indemnifications. Consequently, any future liabilities resulting from these indemnifications cannot reasonably be estimated or accrued. Product Warranty Liabilities Refer to Revenue Recognition in Note 2, "Significant Accounting Policies," for additional information related to the warranties we provide to customers. In the event a warranty claim based on defective materials exists, we may be able to recover some of the cost of the claim from the vendor from whom the materials were purchased. Our ability to recover some of the costs will depend on the terms and conditions to which we agreed when the materials were purchased. When a warranty claim is made, the only collateral available to us is the return of the inventory from the customer making the warranty claim. Historically, when customers make a warranty claim, we either replace the product or provide the customer with a credit. We generally do not rework the returned product. Our policy is to accrue for warranty claims when a loss is both probable and estimable. This is accomplished by accruing for estimated returns and estimated costs to replace the product at the time the related revenue is recognized. Liabilities for warranty claims have historically not been material. In some instances, customers may make claims for costs they incurred or other damages related to a claim. Environmental Remediation Liabilities Our operations and facilities are subject to U.S. and non-U.S. laws and regulations governing the protection of the environment and our employees, including those governing air emissions, water discharges, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites. We could incur substantial costs, including cleanup costs, fines, civil or criminal sanctions, or third-party property damage or personal injury claims, in the event of violations or liabilities under these laws and regulations, or non-compliance with the environmental permits required at our facilities. Potentially significant expenditures could be required in order to comply with environmental laws that may be adopted or imposed in the future. We are, however, not aware of any threatened or pending material environmental investigations, lawsuits, or claims involving us or our operations. Legal Proceedings and Claims We are regularly involved in a number of claims and litigation matters in the ordinary course of business. Most of our litigation matters are third-party claims related to patent infringement allegations or for property damage allegedly caused by our products, but some involve allegations of personal injury or wrongful death. Although it is not feasible to predict the outcome of these matters, based upon our experience and current information known to us, we do not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on our results of operations, financial position, and/or cash flows. We account for litigation and claims losses in accordance with FASB ASC Topic 450, Contingencies . Under FASB ASC Topic 450, loss contingency provisions are recognized for probable and estimable losses at our best estimate of a loss or, when a best estimate cannot be made, at our estimate of the minimum loss. These estimates are often developed prior to knowing the amount of the ultimate loss, require the application of considerable judgment, and are refined each accounting period as additional information becomes known. Accordingly, we are often initially unable to develop a best estimate of loss and therefore the minimum amount, which could be an immaterial amount, is recognized. As information becomes known, either the minimum loss amount is increased, or a best estimate can be made, generally resulting in additional loss provisions. A best estimate amount may be changed to a lower amount when events result in an expectation of a more favorable outcome than previously expected. Pending Litigation and Claims: We are a defendant in a lawsuit, Wasica Finance Gmbh et al v. Schrader International Inc. et al, Case No. 13-1353-CPS, U.S.D.C., Delaware, in which the claimant alleges infringement of their patent (US 5,602,524) in connection with our tire pressure monitoring system ("TPMS") products. The patent in question has expired, and as a result, the claimant is seeking damages for past alleged infringement with interest and costs. Should the claimant prevail, these amounts could be material. We have denied liability and have been defending the litigation. Trial is currently expected in February 2020 . We believe that a loss related to this matter is probable, but do not believe such loss will be material. We were a defendant in a lawsuit, Metal Seal Precision, Ltd. v. Sensata Technologies Inc., Case No. 2017-0518-BCSI, MA Superior Court (Suffolk County) , in which the claimant, a supplier of certain metal parts used in the manufacture of our products, alleged breach of contract, breach of covenant of good faith and fair dealing, and anticipatory repudiation. The dispute arose out of an agreement under which Metal Seal alleged that we did not meet certain purchase requirements, resulting in damages and lost profits. On November 26, 2019, the parties agreed to settle this lawsuit and terminate the underlying supply agreement through an asset purchase agreement (the “MS Purchase Agreement”), whereby Sensata would purchase certain equipment and assets from Metal Seal for $28.0 million (the “Purchase Price”). The parties executed and closed the MS Purchase Agreement on December 13, 2019, and the lawsuit was formally dismissed by the Superior Court on December 24, 2019. We intend to use the assets and equipment purchased in this transaction to expand our internal production of certain parts previously supplied by Metal Seal. As a result of the termination of the underlying supply agreement and execution of the MS Purchase Agreement, we recorded $10.2 million of the Purchase Price as a capital expense for the acquired assets, with the remaining $17.8 million , representing the amount by which the Purchase Price exceeded the fair value of the purchased equipment and assets, recorded in restructuring and other charges, net.

Shareholders' Equity

Shareholders' Equity	12 Months Ended
	Dec. 31, 2019
Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity Treasury Shares Ordinary shares repurchased by us are recognized, measured at cost, and presented as treasury shares on our consolidated balance sheets, resulting in a reduction of shareholders' equity. In connection with the Merger, all then outstanding treasury shares were canceled in accordance with U.K. law. Accordingly, we (1) derecognized the total purchase price of these treasury shares, (2) recognized a reduction to ordinary shares at an amount equal to the total par value of such shares, and (3) recognized a reduction to retained earnings at an amount equal to the excess of the total repurchase price over the total par value of the then outstanding treasury shares, or $286.1 million . From time to time, our Board of Directors has authorized various share repurchase programs. Under these programs, we may repurchase ordinary shares at such times and in amounts to be determined by our management, based on market conditions, legal requirements, and other corporate considerations, on the open market or in privately negotiated transactions, provided that such transactions were completed pursuant to an agreement and with a third party approved by our shareholders at the annual general meeting. The authorized amount of our various share repurchase programs may be modified or terminated by our Board of Directors at any time. During the year ended December 31, 2018 , we repurchased ordinary shares under a $400.0 million share repurchase program authorized by our Board of Directors in May 2018 . During the year ended December 31, 2019 , we repurchased ordinary shares under a $250.0 million share repurchase program authorized by our Board of Directors in October 2018 (the "October 2018 Program") and a $500.0 million share repurchase program authorized by our Board of Directors in July 2019 (the "July 2019 Program"). The October 2018 Program was terminated upon commencement of the July 2019 Program. As a result of certain aspects of U.K. law, we discontinued the practice of reissuing treasury shares as part of our share-based compensation programs upon completion of the Merger. The number of treasury shares reissued prior to completion of the Merger was not material.

Business Combinations [Abstract]
Acquisitions and Divestitures	Acquisitions and Divestitures Other acquisition On September 13, 2019 we completed one acquisition for approximately $30.8 million , net of cash acquired and subject to customary post-closing adjustments. This business is being integrated into our Sensing Solutions segment. The majority of the purchase price allocation, which is preliminary as of December 31, 2019 , was to completed technologies, customer relationships, and goodwill. We are in the process of completing our assessment of the fair values of assets acquired and liabilities assumed. GIGAVAC merger On September 24, 2018 , we entered into an agreement and plan of merger with GIGAVAC, whereby GIGAVAC would merge with one of our wholly-owned subsidiaries, thereby becoming a wholly-owned subsidiary of Sensata. On October 31, 2018 , we completed the acquisition of GIGAVAC for cash consideration of approximately $231.1 million , net of cash received. In connection with the acquisition, an additional $12.0 million related to compensation arrangements entered into with certain GIGAVAC employees and shareholders will be paid on or before the second anniversary of the transaction. Based in Carpinteria, California, GIGAVAC has more than 270 employees and is a leading producer of high voltage contactors and fuses that are mission-critical components for electric vehicles and equipment. It provides solutions that enable electrification in demanding environments within the automotive, battery storage, industrial, and HVOR end markets. We acquired GIGAVAC to increase our content and capabilities for electrification, including products such as cars, delivery trucks, buses, material handling equipment, and charging stations. Portions of GIGAVAC are being integrated into each of our operating segments. The following table summarizes the allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed: Net working capital, excluding cash $ 17,132 Property, plant and equipment 4,384 Goodwill 114,461 Other intangible assets 122,742 Other assets 63 Deferred income tax liabilities (27,072 ) Other long-term liabilities (602 ) Fair value of net assets acquired, excluding cash and cash equivalents 231,108 Cash and cash equivalents 359 Fair value of net assets acquired $ 231,467 The allocation of purchase price related to this merger was finalized in the fourth quarter of 2019 and was based on management’s judgments after evaluating several factors, including valuation assessments of tangible and intangible assets. The goodwill of $114.5 million represents future economic benefits expected to arise from synergies from combining operations and the extension of existing customer relationships. The amount of goodwill recognized that is expected to be deductible for tax purposes is not material. In connection with the allocation of purchase price to the assets acquired and liabilities assumed, we identified certain definite-lived intangible assets. The following table presents the acquired definite-lived intangible assets, their estimated fair values, and weighted average lives: Acquisition Date Fair Value Weighted-Average Lives (years) Acquired definite-lived intangible assets: Customer relationships $ 74,500 10 Completed technologies 31,040 13 Tradenames 15,400 15 Other 1,802 6 Total definite-lived intangible assets acquired $ 122,742 12 The definite-lived intangible assets were valued using the income approach. We used the relief-from-royalty method to value completed technologies and tradenames, and we used the multi-period excess earnings method to value customer relationships. These valuation methods incorporate assumptions including expected discounted future cash flows resulting from either the future estimated after-tax royalty payments avoided as a result of owning the completed technologies or the future earnings related to existing customer relationships. Valves Business Divestiture In August 2018 we completed the divestiture of the Valves Business to Pacific Industrial Co. Ltd. (together with its affiliates, "Pacific"). Contemporaneous with the closing of the sale, Sensata and Pacific entered into a long-term supply agreement, which imposes an obligation on us to purchase minimum quantities of product from Pacific over a period of nearly five years . In exchange for selling the Valves Business and entering into the long-term supply agreement, we received cash consideration from Pacific of approximately $165.5 million , net of $11.8 million of cash and cash equivalents sold. We recognized a (pre-tax) gain on sale of $64.4 million , which is presented in restructuring and other charges, net. In addition, we recognized $5.9 million of costs to sell the Valves Business, which are also presented in restructuring and other charges, net. Refer to Note 5, "Restructuring and Other Charges, Net," for additional information. We determined that the terms of the long-term supply agreement entered into concurrent with the divestiture of the Valves Business were not at market. Accordingly, we recognized a liability of $16.4 million , measured at fair value, which represented the fair value of the off-market component of the supply agreement. The Valves Business, which we acquired in fiscal year 2014 as part of our acquisition of Schrader, manufactured mechanical valves for pressure applications in tires and fluid controls and assembled tire hardware aftermarket products with manufacturing locations in the U.S. and Europe. The sale did not include our TPMS business and the Global TPMS Aftermarket business. The Valves Business was included in our Performance Sensing segment (and reporting unit). We allocated goodwill to the Valves Business based on its fair value relative to the fair value of the retained Performance Sensing reporting unit.

Fair Value Disclosures [Abstract]
Fair Value Measures	Fair Value Measures Our assets and liabilities recorded at fair value have been categorized based upon a fair value hierarchy in accordance with FASB ASC Topic 820. The levels of the fair value hierarchy are described below: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets and liabilities that we have the ability to access at the measurement date. • Level 2 inputs utilize inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. • Level 3 inputs are unobservable inputs for the asset or liability, allowing for situations where there is little, if any, market activity for the asset or liability. Measured on a Recurring Basis The fair values of our assets and liabilities measured at fair value on a recurring basis as of as of December 31, 2019 and 2018 are as shown in the below table. All fair value measures presented are categorized in Level 2 of the fair value hierarchy. As of December 31, 2019 2018 Assets measured at fair value: Foreign currency forward contracts $ 23,561 17,871 Commodity forward contracts 3,623 831 Total assets measured at fair value $ 27,184 18,702 Liabilities measured at fair value: Foreign currency forward contracts $ 1,959 5,165 Commodity forward contracts 462 4,137 Total liabilities measured at fair value $ 2,421 9,302 Refer to Note 2, "Significant Accounting Policies," for additional information related to the methods used to estimate the fair value of our financial instruments, and refer Note 19, "Derivative Instruments and Hedging Activities," for additional information related to the inputs used to determine these fair value measurements and the nature of the risks that these derivative instruments are intended to mitigate. Although we have determined that the majority of the inputs used to value our derivative instruments fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to appropriately reflect both our own non-performance risk and the respective counterparties' non-performance risk in the fair value measurement. As of December 31, 2019 and 2018 , we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivatives in their entirety are classified in Level 2 in the fair value hierarchy. Measured on a Nonrecurring Basis We evaluated our goodwill and other indefinite-lived intangible assets for impairment as of October 1, 2019 . Refer to Note 11, "Goodwill and Other Intangible Assets, Net" for additional information. Based on these analyses, we determined that no impairments were required. As of December 31, 2019 , no events or changes in circumstances occurred that would have triggered the need for an additional impairment review of goodwill or other indefinite-lived intangible assets. Financial Instruments Not Recorded at Fair Value The following table presents the carrying values and fair values of financial instruments not recorded at fair value in the consolidated balance sheets as of December 31, 2019 and 2018 .

In addition to the above, we hold certain equity investments that do not have readily determinable fair values for which we use the measurement alternative prescribed in FASB ASC Topic 321 . Such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. There were no impairments or changes resulting from observable transactions for any of these investments, and no adjustments have been made to their carrying values. Refer to the table below for a detail of the carrying values of these investments, each of which are included in other assets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We utilize derivative instruments that are designated and qualify as hedges of the exposure to variability in expected future cash flows. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on these hedging instruments with the earnings effect of the hedged forecasted transactions. We may enter into other derivative contracts that are intended to economically hedge certain risks, even though we elect not to apply hedge accounting under FASB ASC Topic 815. Derivative financial instruments not designated as hedges are used to manage our exposure to certain risks, not for trading or speculative purposes. Refer to Note 2, "Significant Accounting Policies," for additional information related to the valuation techniques and accounting policies regarding derivative instruments and hedging activities. Hedges of Foreign Currency Risk We are exposed to fluctuations in various foreign currencies against our functional currency, the USD. We enter into forward contracts for certain of these foreign currencies to manage this exposure. We currently have outstanding foreign currency forward contracts that qualify as cash flow hedges intended to offset the effect of exchange rate fluctuations on forecasted sales and certain manufacturing costs. We also have outstanding foreign currency forward contracts that are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities, which are not designated for hedge accounting treatment in accordance with FASB ASC Topic 815. For each of the years ended December 31, 2019 , 2018 , and 2017 , amounts excluded from the assessment of effectiveness of our foreign currency forward agreements that are designated as cash flow hedges were not material. As of December 31, 2019 , we estimate that $20.1 million of net gains will be reclassified from accumulated other comprehensive loss to earnings during the twelve month period ending December 31, 2020 . As of December 31, 2019 , we had the following outstanding foreign currency forward contracts: Notional Effective Date(s) Maturity Date(s) Index (Exchange Rates) Weighted- Average Strike Rate Hedge Designation (1) 22.0 EUR December 27, 2019 January 31, 2020 Euro ("EUR") to USD 1.12 USD Not designated 340.3 EUR Various from March 2018 to December 2019 Various from January 2020 to November 2021 EUR to USD 1.17 USD Cash flow hedge 425.0 CNY December 23, 2019 January 31, 2020 USD to Chinese Renminbi ("CNY") 7.04 CNY Not designated 326.0 CNY December 13, 2019 Various from January to December 2020 USD to CNY 7.07 CNY Cash flow hedge 594.0 JPY December 23, 2019 January 31, 2020 USD to Japanese Yen ("JPY") 109.07 JPY Not designated 24,046.6 KRW Various from February 2018 to December 2019 Various from January 2020 to November 2021 USD to Korean Won ("KRW") 1,135.19 KRW Cash flow hedge 22.0 MYR December 23, 2019 January 31, 2020 USD to Malaysian Ringgit ("MYR") 4.12 MYR Not designated 150.0 MXN December 27, 2019 January 31, 2020 USD to Mexican Peso ("MXN") 19.00 MXN Not designated 2,871.0 MXN Various from February 2018 to December 2019 Various from January 2020 to November 2021 USD to MXN 20.81 MXN Cash flow hedge 50.8 GBP Various from March 2018 to December 2019 Various from January 2020 to November 2021 British Pound Sterling ("GBP") to USD 1.31 USD Cash flow hedge ______________________________________ (1) Derivative financial instruments not designated as hedges are used to manage our exposure to currency exchange rate risk. They are intended to preserve the economic value, and they are not used for trading or speculative purposes. Hedges of Commodity Risk We enter into commodity forward contracts in order to limit our exposure to variability in raw material costs that is caused by movements in the price of underlying metals. The terms of these forward contracts fix the price at a future date for various notional amounts associated with these commodities. These instruments are not designated for hedge accounting treatment in accordance with FASB ASC Topic 815. As of December 31, 2019 , we had the following outstanding commodity forward contracts: Commodity Notional Remaining Contracted Periods Weighted-Average Strike Price Per Unit Silver 855,297 troy oz.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We operate in, and report financial information for, the following two reportable segments: Performance Sensing and Sensing Solutions, each of which is also an operating segment. Our operating segments are businesses that we manage as components of an enterprise, for which separate financial information is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and assess performance. An operating segment’s performance is primarily evaluated based on segment operating income, which excludes amortization of intangible assets, restructuring and other charges, net, and certain corporate costs/credits not associated with the operations of the segment, including share-based compensation expense and a portion of depreciation expense associated with assets recorded in connection with acquisitions. Corporate and other costs excluded from an operating segment’s performance are separately stated below and also include costs that are related to functional areas such as finance, information technology, legal, and human resources. We believe that segment operating income, as defined above, is an appropriate measure for evaluating the operating performance of our segments. However, this measure should be considered in addition to, and not as a substitute for, or superior to, operating income or other measures of financial performance prepared in accordance with U.S. GAAP. The accounting policies of each of our reportable segments are materially consistent with those described in Note 2, "Significant Accounting Policies." Performance Sensing primarily serves the automotive and HVOR industries through development and manufacture of sensors, high-voltage contactors, and other products used in mission-critical systems and applications such as those in subsystems of automobiles, on-road trucks, and off-road equipment (e.g., tire pressure monitoring, thermal management, air conditioning, and regenerative braking). Our products are used in subsystems that, among other things, improve operating performance and efficiency as well as address environmental or safety concerns. Sensing Solutions primarily serves the industrial and aerospace industries through development and manufacture of a broad portfolio of application-specific sensor and control products used in the aerospace market and a diverse range of industrial markets, including the small appliance, HVAC, semiconductor, material handling, factory automation, and water management markets. Some of the products the segment sells include pressure, temperature, and position sensors, motor and compressor protectors, solid state relays, bimetal electromechanical controls, thermal and magnetic-hydraulic circuit breakers, power inverters, and charge controllers. The following table presents net revenue and segment operating income for the reported segments and other operating results not allocated to the reported segments for the years ended December 31, 2019 , 2018 , and 2017 : For the year ended December 31, 2019 2018 2017 Net revenue: Performance Sensing $ 2,546,016 $ 2,627,651 $ 2,460,600 Sensing Solutions 904,615 893,976 846,133 Total net revenue $ 3,450,631 $ 3,521,627 $ 3,306,733 Segment operating income (as defined above): Performance Sensing $ 648,744 $ 712,682 $ 664,186 Sensing Solutions 291,261 293,009 277,450 Total segment operating income 940,005 1,005,691 941,636 Corporate and other (186,674 ) (203,764 ) (205,824 ) Amortization of intangible assets (142,886 ) (139,326 ) (161,050 ) Restructuring and other charges, net (53,560 ) 47,818 (18,975 ) Operating income 556,885 710,419 555,787 Interest expense, net (158,554 ) (153,679 ) (159,761 ) Other, net (7,908 ) (30,365 ) 6,415 Income before taxes $ 390,423 $ 526,375 $ 402,441 No customer exceeded 10% of our net revenue in any of the periods presented.

Leases

Leases [Abstract]
Leases	Leases We occupy leased facilities with initial terms ranging up to 20 years . The lease agreements frequently include options to renew for additional periods or to purchase the leased assets and generally require that we pay taxes, insurance, and maintenance costs. We also lease certain vehicles and equipment. Depending on the specific terms of the leases, our obligations are in two forms: finance leases and operating leases. As discussed in Note 2, "Significant Accounting Policies," we adopted FASB ASC Topic 842 on January 1, 2019, using the modified retrospective transition method. We have elected to apply the package of practical expedients and the land easement practical expedient. We have not elected to apply the hindsight practical expedient. As a result of this adoption, we classify most leases as either finance or operating leases and recognize a related lease liability and right-of-use asset on our consolidated balance sheets. Our accounting for finance leases remains unchanged after the adoption of FASB ASC Topic 842. We have elected to account for leases with a term of one year or less (short-term leases) using a method similar to the operating lease model under FASB ASC Topic 840, Leases (i.e. they are not recorded on the consolidated balance sheets). We elected to apply the transition provisions of this guidance, including its disclosure requirements, at its date of adoption instead of at the beginning of the earliest comparative period presented. Accordingly, we have not restated our consolidated balance sheet as of December 31, 2018. There was no cumulative effect of adoption on our retained earnings or any other components of equity. The below adjustments were made to our consolidated balance sheet on January 1, 2019 to reflect the new guidance: December 31, 2018 Adjustment January 1, 2019 Prepaid expenses and other current assets $ 113,234 $ (253 ) $ 112,981 Other intangible assets, net $ 897,191 $ (1,510 ) $ 895,681 Other assets $ 86,890 $ 58,496 $ 145,386 Accrued expenses and other current liabilities $ 218,130 $ 12,119 $ 230,249 Other long-term liabilities $ 39,277 $ 44,614 $ 83,891 The table below presents the amounts recognized and location of recognition in our consolidated balance sheet as of December 31, 2019 related to our operating and finance leases: December 31, 2019 Operating lease right-of-use assets: Other assets $ 55,333 Total operating lease right-of-use assets $ 55,333 Operating lease liabilities: Accrued expenses and other current liabilities $ 11,543 Other long-term liabilities 45,457 Total operating lease liabilities $ 57,000 Finance lease right-of-use assets: Property, plant and equipment, at cost $ 49,714 Accumulated depreciation (24,316 ) Property, plant and equipment, net $ 25,398 Finance lease liabilities: Current portion of long-term debt, finance lease and other financing obligations $ 1,974 Finance lease and other financing obligations, less current portion 28,669 Total finance lease liabilities $ 30,643 We have material finance leases for facilities in Baoying, China and Attleboro, Massachusetts. As of December 31, 2019 and 2018 , the combined finance lease obligation outstanding for these facilities was $29.4 million and $30.4 million , respectively. The table below presents the lease liabilities arising from obtaining right-of-use assets in the year ended December 31, 2019 : For the year ended December 31, 2019 Operating leases $ 5,423 Finance leases $ — For finance leases, the consolidated statements of operations include separate recognition of interest on the lease liability and amortization of the right-of-use asset. For operating leases, the consolidated statements of operations include a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a straight-line basis. The table below presents our total lease cost for the year ended December 31, 2019 (short-term lease cost was not material for the year ended December 31, 2019 ): For the year ended December 31, 2019 Operating lease cost $ 16,124 Finance lease cost: Amortization of right-of-use assets $ 1,808 Interest on lease liabilities 2,695 Total finance lease cost $ 4,503 Rent expense for the years ended December 31, 2018 and 2017 (prior to the adoption of FASB ASC Topic 842) was $21.0 million and $19.7 million , respectively. Cash flows from operating activities include (1) interest on finance lease liabilities and (2) payments arising from operating leases. Cash flows from financing activities include repayments of the principal portion of finance lease liabilities. The table below presents the cash paid related to our operating and finance leases for the year ended December 31, 2019 : For the year ended December 31, 2019 Operating cash flows from operating leases $ 15,911 Operating cash flows from finance leases $ 2,731 Financing cash flows from finance leases $ 1,933 The table below presents the weighted-average remaining lease term of our operating and finance leases (in years): December 31, 2019 Operating leases 8.1 Finance leases 12.6 Our lease liabilities are initially measured at the present value of the lease payments not yet paid, discounted using our incremental borrowing rate for a period that is comparable to the remaining lease term. Upon adoption of FASB ASC Topic 842, we initially measured our operating lease liabilities using this methodology, while our accounting for finance leases remained unchanged. We use our incremental borrowing rate, adjusted for collateralization, because the discount rate implicit in our leases are generally not readily determinable.

Sensata Technologies Holding plc (Parent Company)—Schedule I—Condensed Financial Information of Sensata Technologies Holding plc ("Sensata plc"), included in this Annual Report on Form 10-K (this "Report"), provides all parent company information that is required to be presented in accordance with the United States (the "U.S.") Securities and Exchange Commission ("SEC") rules and regulations for financial statement schedules. The accompanying condensed financial statements have been prepared in accordance with the reduced disclosure requirements permitted by the SEC. Sensata plc and subsidiaries' audited consolidated financial statements are included elsewhere in this Report. On September 28, 2017, the Board of Directors of Sensata Technologies Holding N.V. ("Sensata N.V.") unanimously approved a plan to change our location of incorporation from the Netherlands to the United Kingdom (the "U.K."). To effect this change, on February 16, 2018 the shareholders of Sensata N.V. approved a cross-border merger between Sensata N.V. and Sensata plc, a newly formed, public limited company incorporated under the laws of England and Wales, with Sensata plc being the surviving entity (the "Merger"). We received approval of the Merger by the U.K. High Court of Justice, and the Merger was completed, on March 28, 2018. As a result thereof, Sensata plc became the publicly-traded parent of the subsidiary companies that were previously controlled by Sensata N.V., with no changes made to the business being conducted by us prior to the Merger. Due to the fact that the Merger was a business combination between entities under common control, the assets and liabilities exchanged were accounted for at their carrying values. Sensata plc conducts limited separate operations and acts primarily as a holding company. Sensata plc has no direct outstanding debt obligations. However, Sensata Technologies B.V., an indirect, wholly-owned subsidiary of Sensata plc, is limited in its ability to pay dividends or otherwise make distributions to its immediate parent company and, ultimately, to Sensata plc, under its senior secured credit facilities and the indentures governing its senior notes. For a discussion of the debt obligations of the subsidiaries of Sensata plc, refer to Note 14, "Debt," of Sensata plc and subsidiaries' audited consolidated financial statements included elsewhere in this Report (the "Consolidated Financial Statements"). All U.S. dollar amounts presented except per share amounts are stated in thousands, unless otherwise indicated. For a discussion of the commitments and contingencies of the subsidiaries of Sensata plc, refer to Note 15, "Commitments and Contingencies," of the Consolidated Financial Statements.

Accounting Policies [Abstract]
Basis of Accounting	Basis of Presentation The accompanying audited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and present separately our financial position, results of operations, comprehensive income, cash flows, and changes in shareholders’ equity.
Reclassification	Certain reclassifications have been made to prior periods to conform to current period presentation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with U.S. GAAP requires us to exercise our judgment in the process of applying our accounting policies. It also requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies at the date of the financial statements and the reported amounts of net revenue and expense during the reporting periods. Estimates are used when accounting for certain items such as allowance for doubtful accounts and sales returns, depreciation and amortization, inventory obsolescence, asset impairments (including goodwill and other intangible assets), contingencies, the value of certain equity awards and the measurement of share-based compensation, the determination of accrued expenses, certain asset valuations including deferred tax asset valuations, the useful lives of plant and equipment, measurement of our post-retirement benefit obligations, and the identification, valuation, and determination of useful lives of identifiable intangible assets acquired in business combinations. The accounting estimates used in the preparation of the consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained, and as the operating environment changes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition We recognize revenue to depict the transfer of promised goods to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods. In order to achieve this, we use the five step model outlined in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers . This five step model requires us to identify the contract with the customer, identify the performance obligation(s) in the contract, determine the transaction price, allocate the transaction price to the performance obligation(s), and recognize revenue when (or as) we satisfy the performance obligation(s). The vast majority of our contracts (as defined in FASB ASC Topic 606) are customer purchase orders ("POs" and each, a "PO") that require us to transfer specified quantities of tangible products to our customers. These performance obligations are generally satisfied within a short period of time. Amounts billed to our customers for shipping and handling after control has transferred are recognized as revenue and the related costs that we incur are presented in cost of revenue. In determining the transaction price, we evaluate whether the consideration promised in the contract includes a variable amount and, if applicable, we include in the transaction price some or all of an amount of variable consideration only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration may be explicitly stated in the contract or implied based on our customary practices. Examples of variable consideration present in our contracts include rights of return, in the case of a defective or non-conforming product, and trade discounts, including early payment discounts and retrospective volume discounts. Such variable consideration has not historically been material in relation to our net revenue. Our contract terms generally require the customer to make payment shortly after (that is, less than one year) the shipment date. In such instances, we do not consider the effects of a significant financing component in determining the transaction price. Lastly, we exclude from our determination of the transaction price value-added tax and other similar taxes. Our performance obligations are satisfied, and revenue is recognized, when control of the product is transferred to the customer. The transfer of control generally occurs at the point in time the product is shipped from our warehouse or, less often, at the point in time it is received by the customer, depending on the specific terms of the arrangement. Many of our products are designed and engineered to meet customer specifications. These activities, and the testing of our products to determine compliance with those specifications, occur prior to any revenue being recognized. Products are then manufactured and sold to customers. However, in certain cases, pre-production activities are a performance obligation in a customer PO, and revenue is recognized when the performance obligation is satisfied. Customer arrangements do not involve post-installation or post-sale testing and acceptance. Our standard terms of sale provide our customers with a warranty against faulty workmanship and the use of defective materials, which is not considered a distinct performance obligation in accordance with FASB ASC Topic 606. Depending on the product, we generally provide such warranties for a period of twelve to eighteen months after the date we ship the product to our customer or for a period of twelve months after the date the customer resells our product, whichever comes first. Our liability associated with this warranty is, at our option, to repair the product, replace the product, or provide the customer with a credit. We do not offer separately priced extended warranty or product maintenance contracts. We also sell products to customers under negotiated agreements or where we have accepted the customer’s terms of purchase. In these instances, we may provide additional warranties for longer durations, consistent with differing end market practices, and where our liability is not limited. In addition, many sales take place in situations where commercial or civil codes, or other laws, would imply various warranties and restrict limitations on liability.
Share-Based Compensation	Share-Based Compensation We measure at fair value any new or modified share-based compensation arrangements with employees, such as stock options and restricted securities, and recognize as compensation expense that fair value over the requisite service period as required in accordance with FASB ASC Topic 718, Compensation—Stock Compensation . Share-based compensation expense is generally recognized as a component of selling, general and administrative ("SG&A") expense, which is consistent with where the related employee costs are presented, however, such costs, or a portion thereof, may be capitalized provided certain criteria are met. Share-based awards may be subject to either cliff vesting (i.e., the entire award vests on a particular date) or graded vesting (i.e., portions of the award vest at different points in time). In accordance with FASB ASC Topic 718, compensation expense associated with share-based awards subject to cliff vesting must be recognized on a straight-line basis. For awards without performance conditions that are subject to graded vesting, companies have the option to recognize compensation expense either on a straight-line or accelerated basis. We have elected to recognize compensation expense for these awards on a straight-line basis. However, awards that are subject to both graded vesting and performance conditions must be expensed on an accelerated basis. We estimate the fair value of options on the grant date using the Black-Scholes-Merton option-pricing model. Key inputs and assumptions used in this model are as follows: • The fair value of the underlying ordinary shares. This is determined as the closing price of our ordinary shares on the New York Stock Exchange (the "NYSE") on the grant date. • The expected term. This is determined based upon our own historical average term of exercised and outstanding options. • Expected volatility. We consider our own historical volatility, as well as our implied volatility, in estimating expected volatility for stock options. Implied volatility provides a forward-looking indication and may offer insight into expected volatility. • Risk-free interest rate. The risk-free interest rate is based on the yield for a U.S. Treasury security having a maturity similar to the expected term of the related option grant. • Expected dividend yield. The dividend yield of 0% is based on our history of having never declared or paid any dividends on our ordinary shares, and our current intention of not declaring any such dividends in the foreseeable future. Restricted securities are valued using the closing price of our ordinary shares on the NYSE on the grant date. Certain of our restricted securities include performance conditions that require us to estimate the probable outcome of the performance condition. Compensation expense is recognized if it is probable that the performance condition will be achieved. Under the fair value recognition provisions of FASB ASC Topic 718, we recognize share-based compensation net of estimated forfeitures. Accordingly, we only recognize compensation expense for those awards expected to vest over the requisite service period. Compensation expense recognized for each award ultimately reflects the number of units that actually vest.
Financial Instruments	Financial Instruments Our financial instruments include derivative instruments, debt instruments, debt and equity investments, and trade accounts receivable. Derivative financial instruments: We account for our derivative financial instruments in accordance with FASB ASC Topic 820, Fair Value Measurements and Disclosures and FASB ASC Topic 815, Derivatives and Hedging . In accordance with FASB ASC Topic 815, we recognize all derivatives on the balance sheet at fair value. The fair value of our derivative financial instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. These analyses utilize observable market-based inputs, including foreign currency exchange rates and commodity forward curves, and reflect the contractual terms of these instruments, including the period to maturity. Derivative instruments that are designated and qualify as hedges of the exposure to changes in the fair value of an asset, liability, or commitment, and that are attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments that are designated and qualify as hedges of the exposure to variability in expected future cash flows are considered cash flow hedges. Derivative instruments may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Currently, our derivative instruments that are designated as accounting hedges are all cash flow hedges. We also hold derivative instruments that are not designated as accounting hedges. The accounting for changes in the fair value of our cash flow hedges depends on whether we have elected to designate the derivative as a hedging instrument for accounting purposes and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. In accordance with FASB ASC Topic 815, both the effective and ineffective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recognized in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period in which the hedged forecasted transaction affects earnings. Changes in the fair value of derivative instruments that are not designated as accounting hedges are recognized immediately in other, net. Refer to Note 16, "Shareholders' Equity," and Note 19, "Derivative Instruments and Hedging Activities," for additional information related to the reclassification of amounts from accumulated other comprehensive loss into earnings. We present the cash flows arising from our derivative financial instruments in a manner consistent with the presentation of cash flows that relate to the underlying hedged items. We incorporate credit valuation adjustments to appropriately reflect both our own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of non-performance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. We do not offset the fair value amounts recognized for derivative instruments against fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral. We maintain derivative instruments with major financial institutions of investment grade credit rating and monitor the amount of credit exposure to any one issuer. We believe there are no significant concentrations of risk associated with our derivative instruments. Refer to Note 19, "Derivative Instruments and Hedging Activities," for additional information related to our derivative instruments. Debt Instruments: A premium or discount on a debt instrument is recognized on the balance sheet as an adjustment to the carrying amount of the debt liability. In general, amounts paid to creditors are considered a reduction in the proceeds received from the issuance of the debt and are accounted for as a component of the premium or discount on the issuance, not as an issuance cost. Direct and incremental costs associated with the issuance of debt instruments such as legal fees, printing costs, and underwriters' fees, among others, paid to parties other than creditors, are also reported and presented as a reduction of debt on the consolidated balance sheets. Debt issuance costs and premiums or discounts are amortized over the term of the respective financing arrangement using the effective interest method. Amortization of these amounts is included as a component of interest expense, net in the consolidated statements of operations. In accounting for debt refinancing transactions, we apply the provisions of FASB ASC Subtopic 470-50, Modifications and Extinguishments . Our evaluation of the accounting under FASB ASC Subtopic 470-50 is done on a creditor by creditor basis in order to determine if the terms of the debt are substantially different and, as a result, whether to apply modification or extinguishment accounting. In the event that an individual holder of existing debt did not invest in new debt, we apply extinguishment accounting. Borrowings associated with individual holders of new debt that are not holders of existing debt are accounted for as new issuances. Refer to Note 14, "Debt," for additional information related to our debt instruments and transactions. Equity Investments: We measure equity investments (other than those accounted for under the equity method, those that result in consolidation of the investee, and certain other investments) either at fair value, with changes to fair value recognized in net income, or in certain instances, by use of a measurement alternative prescribed in FASB ASC Topic 321, Investments - Equity Securities . Under the measurement alternative, such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Refer to Note 18, "Fair Value Measures," for additional information related to our measurement of financial instruments. Trade accounts receivable: Trade accounts receivable are recognized at invoiced amounts and do not bear interest. Trade accounts receivable are reduced by an allowance for losses on receivables, as described elsewhere in this Note 2. Concentrations of risk with respect to trade accounts receivable are generally limited due to the large number of customers in various industries and their dispersion across several geographic areas. Although we do not foresee that credit risk associated with these receivables will deviate from historical experience, repayment is dependent upon the financial stability of these
Allowance for Losses on Receivables	Allowance for Losses on Receivables The allowance for losses on receivables is used to present accounts receivable, net at an amount that represents our estimate of the related transaction price recognized as revenue in accordance with FASB ASC Topic 606. The allowance represents an estimate of probable but unconfirmed losses in the receivable portfolio. We estimate the allowance on the basis of specifically identified receivables that are evaluated individually for impairment and a statistical analysis of the remaining receivables determined by reference to past default experience. Customers are generally not required to provide collateral for purchases. The allowance for losses on receivables also includes an allowance for sales returns (variable consideration). Management judgments are used to determine when to charge off uncollectible trade accounts receivable. We base these judgments on the age of the receivable, credit quality of the customer, current economic conditions, and other factors that may affect a customer’s ability and intent to pay.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Businesses acquired are recognized at their fair value on the date of acquisition, with the excess of the purchase price over the fair value of identifiable assets acquired and liabilities assumed recognized as goodwill. Intangible assets acquired may include either definite-lived or indefinite-lived intangible assets, or both. In accordance with the requirements of FASB ASC Topic 350, Intangibles—Goodwill and Other
Goodwill	Goodwill: We have identified six reporting units: Performance Sensing, Electrical Protection, Industrial Sensing, Aerospace, Power Management, and Interconnection. These reporting units have been identified based on the definitions and guidance provided in FASB ASC Topic 350. We periodically review these reporting units to ensure that they continue to reflect the manner in which the business is operated. Certain assets and liabilities relate to the operations of multiple reporting units. We allocate these assets and liabilities to the related reporting units based on methods that we believe are reasonable and supportable, and we apply that allocation method on a consistent basis from year to year. Other assets and liabilities, such as cash and cash equivalents and property, plant and equipment ("PP&E") associated with our corporate offices, and debt, we view as being corporate in nature. Accordingly, we do not assign these assets and liabilities to our reporting units. In the event we reorganize our business, we reassign the assets and liabilities among the affected reporting units using a reasonable and supportable methodology. As businesses are acquired, we assign assets acquired and liabilities assumed to a new or existing reporting unit as of the date of the acquisition. In the event a disposal group meets the definition of a business, goodwill is allocated to the disposal group based on the relative fair value of the disposal group to the retained portion of the related reporting unit. We have the option to first assess qualitative factors to determine whether a quantitative analysis must be performed. The objective of a qualitative analysis is to determine whether it is more likely than not that the fair value of a reporting unit is less than its net book value. If we elect not to use this option, or if we determine that it is more likely than not that the fair value of a reporting unit is less than its net book value, then we perform the first step of the quantitative analysis prescribed by FASB ASC Topic 350. In this step we compare the estimated fair values of our reporting units to their respective net book values, including goodwill, to determine whether there is an indicator of potential impairment. If the net book value of a reporting unit exceeds its estimated fair value, we conduct a second step in which we calculate the implied fair value of goodwill. If the carrying value of the reporting unit’s goodwill exceeds its calculated implied fair value, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of its identifiable assets and liabilities as if the reporting unit had been acquired in a business combination at the date of assessment, and the fair value of the reporting unit was the purchase price paid to acquire the reporting unit. The excess of the fair value of the reporting unit over the sum of the fair values of each of its identifiable assets and liabilities is the implied fair value of goodwill. The fair value measurements of our reporting units are categorized in level 3 of the fair value hierarchy.
Intangible Assets	Indefinite-lived intangible assets: Similar to goodwill, we perform an annual impairment review of our indefinite-lived intangible assets in the fourth quarter of each fiscal year, unless events occur that trigger the need for an earlier impairment review. We have the option to first assess qualitative factors in determining whether it is more likely than not that an indefinite-lived intangible asset is impaired. If we elect not to use this option, or we determine that it is more likely than not that the asset is impaired, we perform a quantitative impairment review that requires us to estimate the fair value of the indefinite-lived intangible asset and compare that amount to its carrying value. We estimate the fair value by using the relief-from-royalty method, which requires us to make assumptions about future conditions impacting the value of the indefinite-lived intangible assets, including projected growth rates, cost of capital, effective tax rates, and royalty rates. Impairment, if any, is based on the excess of the carrying value over the fair value of these assets. Definite-lived intangible assets: Acquisition-related definite-lived intangible assets are amortized on an economic-benefit basis according to the useful lives of the assets, or on a straight-line basis if a pattern of economic benefits cannot be reliably determined. Capitalized software and capitalized software licenses are presented on the consolidated balance sheets as intangible assets. Capitalized software licenses are amortized on a straight-line basis over the lesser of the term of the license or the estimated useful life of the software. Capitalized software is amortized on a straight-line basis over its estimated useful life. Reviews are regularly performed to determine whether facts or circumstances exist that indicate that the carrying values of our definite-lived intangible assets are impaired. If we determine that such facts or circumstances exist, we estimate the recoverability of these assets by comparing the projected undiscounted net cash flows associated with these assets to their respective carrying values. If the sum of the projected undiscounted net cash flows is less than the carrying value of an asset, the impairment charge is measured as the excess of the carrying value over the fair value of that asset. We determine fair value by using the appropriate income approach valuation methodology, depending on the nature of the definite-lived intangible asset.
Income Taxes	Income Taxes We estimate our provision for income taxes in each of the jurisdictions in which we operate. The provision for income taxes includes both our current and deferred tax exposure. Our deferred tax exposure is measured using the asset and liability method, under which deferred income taxes are recognized to reflect the future tax consequences of differences between the tax bases of assets and liabilities and their financial reporting amounts at each balance sheet date, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to reverse or settle. The effect on deferred tax assets and liabilities of a change in statutory tax rates is recognized in the consolidated statements of operations as an adjustment to income tax expense in the period that includes the enactment date. In measuring our deferred tax assets, we consider all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed for all or some portion of the deferred tax assets. If it is determined that it is more likely than not that future tax benefits associated with a deferred tax asset will not be realized, a valuation allowance is provided. As a result, we maintain valuation allowances against the deferred tax assets in jurisdictions that have incurred losses in recent periods and in which it is more likely than not that such deferred tax assets will not be utilized in the foreseeable future. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Reform Act") was signed into law. The Tax Reform Act introduced two new U.S. tax base erosion provisions: the global intangible low-taxed income ("GILTI") and the base erosion and anti-abuse tax ("BEAT"). We elected to account for GILTI in the period in which it is incurred rather than adjusting our deferred tax assets for any future impacts of this provision. Similarly, we account for BEAT tax in the year incurred as a period expense only, and have followed the guidance found in the FASB Staff Q&A, Topic 740, No. 4, Accounting for the Base Erosion Anti-Abuse Tax , which states that an entity does not need to evaluate the potential of paying BEAT in future years on the realization of its deferred tax assets and liabilities. We have followed this guidance in our current tax calculation and evaluation of the realizability of our deferred tax assets. In accordance with FASB ASC Topic 740, Income Taxes , we record uncertain tax positions on the basis of a two-step process. First, we determine whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position. Second, for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the relevant tax authority. Significant judgment is required in evaluating whether our tax positions meet this two-step process. The more-likely-than-not recognition threshold must be met in each reporting period to support continued recognition of any tax benefits claimed, both in the current year, as well as any year which remains open for review by the relevant tax authority at the balance sheet date. Penalties and interest related to uncertain tax positions may be classified as either income taxes or another expense line item in the consolidated statements of operations. We classify interest and penalties related to uncertain tax positions within the provision for/(benefit from) income taxes line of the consolidated statements of operations.
Pension and Other Post-Retirement Benefits	Pension and Other Post-Retirement Benefits We sponsor various pension and other post-retirement benefit plans covering our current and former employees in several countries. The funded status of pension and other post-retirement benefit plans, recognized on our consolidated balance sheets as an asset, current liability, or long-term liability, is measured as the difference between the fair value of plan assets and the benefit obligation at the measurement date. In general, the measurement date coincides with our fiscal year end, however, certain significant events, such as (1) plan amendments, (2) business combinations, (3) settlements or curtailments, or (4) plan mergers, may trigger the need for an interim measurement of both the plan assets and benefit obligations. Benefit obligations represent the actuarial present value of all benefits attributed by the pension formula as of the measurement date to employee service rendered before that date. The value of benefit obligations takes into consideration various financial assumptions, including assumed discount rate and the rate of increase in healthcare costs, and demographic assumptions, including compensation rate increases, retirement patterns, employee turnover rates, and mortality rates. We review these assumptions annually. Our review of demographic assumptions includes analyzing historical patterns and/or referencing industry standard tables, combined with our expectations around future compensation and staffing strategies. The difference between these assumptions and our actual experience results in the recognition of an actuarial gain or loss. Actuarial gains and losses are recorded directly to other comprehensive income or loss. If the total net actuarial gain or loss included in accumulated other comprehensive loss exceeds a threshold of 10% of the greater of the projected benefit obligation or the market related value of plan assets, it is subject to amortization and recorded as a component of net periodic benefit cost over the average remaining service lives of the employees participating in the pension or post-retirement benefit plan. The discount rate reflects the current rate at which the pension and other post-retirement liabilities could be effectively settled, considering the timing of expected payments for plan participants. It is used to discount the estimated future obligations of the plans to the present value of the liability reflected in the financial statements. In estimating this rate in countries that have a market of high-quality, fixed-income investments, we consider rates of return on these investments included in various bond indices, adjusted to eliminate the effects of call provisions and differences in the timing and amounts of cash outflows related to the bonds. In other countries where a market of high-quality, fixed-income investments does not exist, we estimate the discount rate using government bond yields or long-term inflation rates. The expected return on plan assets reflects the average rate of earnings expected on the funds invested to provide for the benefits included in the projected benefit obligation. To determine the expected return on plan assets, we use the fair value of plan assets and consider the historical returns earned by similarly invested assets, the rates of return expected on plan assets in the future, and our investment strategy and asset mix with respect to the plans’ funds. Changes to benefit obligations may also be initiated by a settlement or curtailment. A settlement of a defined benefit obligation is an irrevocable transaction that relieves us (or the plan) of primary responsibility for the defined benefit obligation and eliminates significant risks related to the obligation and the assets used to effect the settlement. The settlement of all or more than a minor portion of the pension obligation constitutes an event that requires recognition of all or part of the net actuarial gains or losses deferred in accumulated other comprehensive loss. Our policy is to apply settlement accounting to the extent our year-to date settlements for a given plan exceed the sum of our forecasted full year service cost and interest cost for that particular plan. A curtailment is an event that significantly reduces the expected years of service of active employees or eliminates for a significant number of employees the accrual of defined benefits for some or all of their future service. The curtailment accounting provisions are applied on a plan-by-plan basis. The total gain or loss resulting from a curtailment is the sum of two distinct elements: (1) prior service cost write-off and (2) curtailment gain or loss. Our policy is that a curtailment event represents one for which we expect a 10% (or greater) reduction in future years of service or an elimination of the accrual of defined benefits for some or all of the future services of 10% (or greater) of the plan's participants. Contributions made to pension and other post-retirement benefit plans are presented as cash used in operations within the consolidated statements of cash flows.
Inventories	Inventories
Property, Plant and Equipment and Other Capitalized Costs	Property, Plant and Equipment and Other Capitalized Costs PP&E is stated at cost, and in the case of plant and equipment, is depreciated on a straight-line basis over its estimated economic useful life. The depreciable lives of plant and equipment are as follows: Buildings and improvements 2 – 40 years Machinery and equipment 2 – 15 years Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated economic useful lives of the improvements. Amortization of leasehold improvements is included in depreciation expense. Assets held under finance leases are recognized at the lower of the present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease. Depreciation expense associated with finance leases is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease, unless ownership is transferred by the end of the lease or there is a bargain purchase option, in which case the asset is depreciated, normally on a straight-line basis, over the useful life that would be assigned if the asset were owned. Expenditures for maintenance and repairs are charged to expense as incurred, whereas major improvements that increase asset values and extend useful lives are capitalized.
Foreign Currency	Foreign Currency We derive a significant portion of our net revenue from markets outside of the U.S. For financial reporting purposes, the functional currency of all of our subsidiaries is the USD because of the significant influence of the USD on our operations. In certain instances, we enter into transactions that are denominated in a currency other than the USD. At the date that such transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured and recorded in USD using the exchange rate in effect at that date. At each balance sheet date, recorded monetary balances denominated in a currency other than USD are adjusted to USD using the exchange rate at the balance sheet date, with gains or losses recognized in other, net in the consolidated statements of operations.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash comprises cash on hand. Cash equivalents are short-term, highly liquid investments that are readily convertible to known amounts of cash, are subject to an insignificant risk of change in value, and have original maturities of three months or less.
Recently Issued Accounting Standards Adopted in the Current Period	Recently issued accounting standards adopted in the current period: In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) , which establishes new accounting and disclosure requirements for leases. FASB ASC Topic 842, Leases , requires lessees to classify most leases as either finance or operating leases and to recognize a lease liability and right-of-use asset. For finance leases, the statements of operations include separate recognition of interest on the lease liability and amortization of the right-of-use asset. For operating leases, the statements of operations include a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a straight-line basis. We adopted the provisions of FASB ASU No. 2016-02 on January 1, 2019 using the modified retrospective transition method. Refer to Note 21, "Leases" for additional information related to this adoption. No other recently issued accounting standards adopted in the current period had a material impact on our consolidated financial position or results of operations. Recently issued accounting standards to be adopted in a future period: There are no recently issued accounting standards to be adopted in future periods that are expected to have a material impact on our consolidated financial position or results of operations.
Legal Proceedings and Claims	Legal Proceedings and Claims We are regularly involved in a number of claims and litigation matters in the ordinary course of business. Most of our litigation matters are third-party claims related to patent infringement allegations or for property damage allegedly caused by our products, but some involve allegations of personal injury or wrongful death. Although it is not feasible to predict the outcome of these matters, based upon our experience and current information known to us, we do not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on our results of operations, financial position, and/or cash flows. We account for litigation and claims losses in accordance with FASB ASC Topic 450, Contingencies . Under FASB ASC Topic 450, loss contingency provisions are recognized for probable and estimable losses at our best estimate of a loss or, when a best estimate cannot be made, at our estimate of the minimum loss. These estimates are often developed prior to knowing the amount of the ultimate loss, require the application of considerable judgment, and are refined each accounting period as additional information becomes known. Accordingly, we are often initially unable to develop a best estimate of loss and therefore the minimum amount, which could be an immaterial amount, is recognized. As information becomes known, either the minimum loss amount is increased, or a best estimate can be made, generally resulting in additional loss provisions. A best estimate amount may be changed to a lower amount when events result in an expectation of a more favorable outcome than previously expected.
