Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Vishay Intertechnology, Inc. (“Vishay” or the “Company”) Note 1 – Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of Vishay and all of its subsidiaries in which a controlling financial interest is maintained. For those consolidated subsidiaries in which the Company’s ownership is less than 100 percent, the outside stockholders’ interests are shown as noncontrolling interest in the accompanying consolidated balance sheets. Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis. Investments in affiliates over which the Company does not have significant influence are accounted for by the cost method. All intercompany transactions, accounts, and profits are eliminated. Revenue Recognition The Company recognizes revenue from contracts with customers when it satisfies the performance obligations within the contract. The Company has framework agreements with many of its customers that contain the terms and conditions of future sales, but do not create enforceable rights or obligations. For revenue recognition purposes, the Company considers the combined purchase orders and the terms and conditions contained within such framework agreements to be contracts. Payment terms for the Company's sales are generally less than sixty days. Substantially all of the Company's receivables historically have been and are expected to continue to be collected within twelve months of the transfer of products to the customer and the Company expects this to continue going forward. Accordingly, the Company does not recognize a financing component of the transaction price. Revenue is measured based on the consideration specified in contracts with customers, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies its performance obligations. The Company analyzes its contracts to determine whether the promise in the contract to construct and transfer goods to the customer is a performance obligation that will be satisfied over time or at a point in time. When the Company's performance does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date, the Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time. The Company has a limited number of contracts for custom products that meet the criteria to recognize revenue over time. The Company's contracts contain two performance obligations: delivery of products and warranty protection. The Company does not sell separate, enhanced, or extended warranty coverage, but through its customary business practices, the Company has created implied service-type warranties, which are accounted for as separate performance obligations. Revenue is allocated between these two performance obligations and recognized as the obligations are satisfied. The allocation of revenue to warranty protection is based on an estimate of expected cost plus margin. The delivery of products performance obligation is satisfied and product sales revenue is recognized when the customer takes control of the products. Warranty revenue is deferred and the warranty protection performance obligation is satisfied and revenue is recognized over the warranty period, which is typically less than twenty four months from sale to end customer. The warranty deferred revenue liability is recorded within Other Accrued Expenses and Other Liabilities on the accompanying consolidated balance sheets. The deferred revenue balance associated with the service-type warranty performance obligations and the components that comprise the change in the deferred revenue balance are not significant. The Company has a broad line of products that it sells to original equipment manufacturers ("OEMs"), electronic manufacturing services ("EMS") companies, which manufacture for OEMs on an outsourcing basis, and independent distributors that maintain large inventories of electronic components for resale to OEMs and EMS companies. The Company recognizes revenue on sales to distributors when the distributor takes control of the products ("sold-to" model). The Company has agreements with distributors that allow distributors a limited credit for unsaleable products, which it terms a "scrap allowance." Consistent with industry practice, the Company also has a "stock, ship and debit" program whereby it considers requests by distributors for credits on previously purchased products that remain in distributors' inventory, to enable the distributors to offer more competitive pricing. In addition, the Company has contractual arrangements whereby it provides distributors with protection against price reductions initiated by the Company after product is sold by the Company to the distributor and prior to resale by the distributor. The Company recognizes the estimated variable consideration to be received as revenue and records a related accrued expense for the consideration not expected to be received, based upon its estimate of product returns, scrap allowances, "stock, ship and debit" credits, and price protection credits that will be attributable to sales recorded through the end of the period. The Company makes these estimates based upon sales levels to its distributors during the period, inventory levels at the distributors, current and projected market conditions, and historical experience under the programs. While the Company utilizes a number of different methodologies to estimate the accruals, all of the methodologies take into account sales levels to distributors during the relevant period, inventory levels at the distributors, current and projected market trends and conditions, recent and historical activity under the relevant programs, changes in program policies, and open requests for credits. These procedures require the exercise of significant judgments. The Company believes that it has a reasonable basis to estimate future credits under the programs. See sales returns and allowances accrual activity in Note 9. The Company pays commissions to external sales representatives on a per-sale basis. Accordingly, these commissions are expensed as incurred because the future amortization period of the asset that the Company otherwise would have recognized is one year or less. Internal staff are not paid commissions. The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the product even if the shipping and handling activities are performed after the customer obtains control. The Company does not evaluate whether shipping and handling activities are promised services to its customers. If control transfers and revenue is recognized for the related products before the shipping and handling activities occur, the related costs of those shipping and handling activities is accrued. The Company applies this accounting policy election consistently to similar types of transactions. See disaggregated revenue information in Note 15 Research and Development Expenses Research and development costs are expensed as incurred. The amount charged to expense for research and development (exclusive of purchased in-process research and development) aggregated $77,377, $70,861, and $69,827, for the years ended December 31, 2021, 2020, and 2019, respectively. The Company spends additional amounts for the development of machinery and equipment for new processes and for cost reduction measures. Income Taxes The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances have been established for deferred tax assets which the Company believes do not meet GAAP criteria of “more likely than not” to be realized. This criterion requires a level of judgment regarding future taxable income, which may be revised due to changes in market conditions, tax laws, or other factors. If the Company’s assumptions and estimates change in the future, valuation allowances established may be increased, resulting in increased tax expense. Conversely, if the Company is ultimately able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been established, then the related portion of the valuation allowance can be released, resulting in decreased tax expense. The Company and its subsidiaries are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite the Company’s belief that its tax return positions are fully supportable. The Company adjusts these reserves in light of changing facts and circumstances and the provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. These accruals for tax-related uncertainties are based on management’s best estimate of potential tax exposures. When particular matters arise, a number of years may elapse before such matters are audited by tax authorities and finally resolved. Favorable resolution of such matters could be recognized as a reduction to the Company’s effective tax rate in the year of resolution. Unfavorable resolution of any particular issue could increase the effective tax rate and may require the use of cash in the year of resolution. The amount included in current liabilities on the accompanying consolidated balance sheets reflect only amounts expected to be settled in cash within one year. See Note 5. Cash, Cash Equivalents, and Short-Term Investments Cash and cash equivalents includes demand deposits and highly liquid investments with maturities of three months or less when purchased. Highly liquid investments with original maturities greater than three months, but less than one year are classified as short-term investments. At December 31, 2021 and 2020, the Company’s short-term investments were comprised of time deposits with financial institutions whose original maturity exceeds three months, but less than one year. Allowance for Credit Losses Effective January 1, 2020, the Company estimates its credit losses on financial instruments using a current expected credit loss model. Prior to January 1, 2020, the Company estimated its credit losses using an incurred loss impairment methodology, which was not materially different than the methodology adopted on January 1, 2020. The Company maintains an allowance for accounts receivable credit losses resulting from the inability of its customers to make required payments. $ , $ , and $ for the years ended , , and , respectively. The Company’s cash equivalents, short-term investments, and restricted investments are accounted for as held-to-maturity debt instruments, at amortized cost. Interest income on these instruments is recorded as Other income on the consolidated statements of operations and interest receivable is recognized as a separate asset and recorded in Prepaid expenses and other current assets on the consolidated balance sheets. The Company has not experienced a credit loss on the principal or interest receivable of its cash equivalents, short-term investments, or restricted investments. The Company pools its cash equivalents, short-term investments, and restricted investments by credit rating of the issuing financial institution and estimates an allowance for credit losses based on the corporate bond default ratios, evaluation of the impact of current and projected economic conditions, and probability of credit loss. Net credit loss expense for cash equivalents, short-term investments, and restricted investments was immaterial for the years ended December 31, 2021 and 2020. The Company does not measure an allowance for credit losses on interest receivable. Any uncollectible interest receivable is recognized by reversing interest income within the fiscal quarter that the interest becomes uncollectible. The Company has an immaterial amount of other short-term held-to-maturity debt instruments recorded within Prepaid expenses and other current assets on the consolidated balance sheets. The Company analyzes these assets on a separate asset basis and estimates an allowance for credit losses based on historical credit loss rates and an evaluation of the impact of current and projected economic conditions. Net credit loss expense for these other short-term held-to-maturity debt instruments was immaterial for the years ended December 31, 2021 and 2020. Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out method, or net realizable value. Inventories are adjusted for estimated obsolescence and written down to net realizable value based upon estimates of future demand, technology developments, and market conditions. Property and Equipment Property and equipment is carried at cost and is depreciated principally by the straight-line method based upon the estimated useful lives of the assets. Machinery and equipment are being depreciated over useful lives of to . Buildings and building improvements are being depreciated over useful lives of to . Construction in progress is not depreciated until the assets are placed in service. The estimated cost to complete construction in progress at was approximately $ . Excluded from the estimated cost to complete construction in progress are costs for projects that have recently begun for which there are no contractual commitments to complete the project, including Depreciation expense was $ , $ , and $ for the years ended , , and , respectively. Gains and losses on the disposal of assets which do not qualify for presentation as discontinued operations are included in the determination of operating margin (within selling, general, and administrative expenses). Individually material gains and losses on disposal are separately disclosed in the notes to the consolidated financial statements. Commitments and Contingencies The Company has commitments for the purchase of assets to complete its construction in progress as disclosed above. The commitment period for substantially all of these purchase commitments is less than one year. The Company expects to have noncancellable purchase commitments with commitment periods in excess of one year associated with its significant facility expansion programs as the programs progress. As of December 31, 2021, there are no material noncancellable commitments associated with these programs. Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. The costs for a specific environmental remediation site are discounted if the aggregate amount of the obligation and the amount and timing of the cash payments for that site are fixed or reliably determinable based upon information derived from the remediation plan for that site. Accrued liabilities for environmental matters recorded at December 31, 2021 and 2020 do not include claims against third parties. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of a business acquired over the fair value of the related net assets at the date of acquisition. Certain intangible assets may be assigned indefinite useful lives. Goodwill and indefinite-lived intangible assets are not amortized but rather are tested for impairment at least annually. These tests are performed more frequently whenever events or changes in circumstances indicate that the assets might be impaired. The Company's business segments (see Note 15) represent its reporting units for goodwill impairment testing purposes. At December 31, 2021 and 2020, respectively, the Company has no recorded indefinite-lived intangible assets. Definite-lived intangible assets are amortized over their estimated useful lives. Patents and acquired technology are being amortized over useful lives of seven years to twenty-five years. Capitalized software is amortized over periods of three years to ten years, primarily included in costs of products sold on the consolidated statements of operations. Customer relationships are amortized over useful lives of five years to twenty years. Noncompete agreements are amortized over periods of three years to ten years. The Company continually evaluates the reasonableness of the useful lives of these assets. GAAP prescribes a quantitative method for determining goodwill impairment. The Company has the option of performing a qualitative assessment before performing the quantitative impairment test. If it is determined, on the basis of qualitative factors, that the fair value of the reporting unit is not more likely than not less than the carrying amount, the quantitative impairment test is not required. If it is determined that the fair value of the reporting unit is more likely than not less than the carrying amount, the quantitative impairment test is required. The Company determines the fair value of the reporting unit and compares that fair value to the net book value of the reporting unit. The fair value of the reporting unit is determined using various valuation techniques, including a comparable companies market multiple approach and a discounted cash flow analysis (an income approach). If the net book value of the reporting unit were to exceed the fair value, the Company would recognize an impairment charge. Impairment of Long-Lived Assets The carrying value of long-lived assets held-and-used, other than goodwill and indefinite-lived intangible assets, is evaluated when events or changes in circumstances indicate the carrying value may not be recoverable or the useful life has changed. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from such asset group are separately identifiable and are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset group. Fair market value is determined primarily using present value techniques based on projected cash flows from the asset group. Losses on long-lived assets held-for-sale, other than goodwill and indefinite-lived intangible assets, are determined in a similar manner, except that fair market values are reduced for anticipated disposal costs. Available-for-Sale Securities Short-term investments and other assets reported on the accompanying consolidated balance sheets include time deposits with financial institutions whose original maturity exceeds three months, but less than one year that are classified as held-to-maturity instruments, and investments in marketable securities that are classified as available-for-sale instruments. The available-for-sale instruments include assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans (see Note 11) and assets that are intended to fund a portion of the Company’s other postretirement benefit obligations outside of the U.S. These assets are reported at fair value, based on quoted market prices as of the end of the reporting period. Unrealized gains and losses are reported as Other Income (Expense) on the consolidated statements of operations. At the time of sale, the assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans, any gains (losses) calculated by the specific identification method are recognized as a reduction (increase) to benefits expense, within selling, general, and administrative expenses. Financial Instruments The Company uses financial instruments in the normal course of its business, including from time to time, derivative financial instruments. Additionally, from time to time, the Company enters into contracts that are not considered derivative financial instruments in their entirety, but that include embedded derivative features. Other financial instruments include cash and cash equivalents, held-to-maturity short-term investments, accounts receivable, and notes payable. The carrying amounts of these financial instruments reported on the accompanying consolidated balance sheets approximate their fair values due to the short-term nature of these assets and liabilities. The fair value measurement accounting guidance establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the Company’s own assumptions. An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Stock-Based Compensation Compensation costs related to stock-based payment transactions are recognized in the consolidated financial statements. The amount of compensation cost is measured based on the grant-date fair value of the equity (or liability) instruments issued. The Company determines compensation cost for restricted stock units ("RSUs") and phantom stock units based on the grant-date fair value of the underlying common stock adjusted for expected dividends paid over the required vesting period for non-participating awards. Compensation cost is recognized over the period that an officer, employee, or non-employee director is required to provide service in exchange for the award. For awards subject to graded vesting, the Company recognizes expense over the service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards. The Company recognizes compensation cost for RSUs that are expected to vest and records cumulative adjustments in the period that the expectation changes. Foreign Currency Translation The Company has significant operations outside of the United States. The Company finances its operations in Europe and certain locations in Asia in local currencies, and accordingly, these subsidiaries utilize the local currency as their functional currency. The Company’s operations in Israel and most significant locations in Asia are largely financed in U.S. dollars, and accordingly, these subsidiaries utilize the U.S. dollar as their functional currency. For those subsidiaries where the local currency is the functional currency, assets and liabilities on the accompanying consolidated balance sheets have been translated at the rate of exchange as of the balance sheet date. Translation adjustments do not impact the consolidated results of operations and are reported as a separate component of stockholders’ equity. Revenues and expenses are translated at the average exchange rate for the year. While the translation of revenues and expenses into U.S. dollars does not directly impact the statement of operations, the translation effectively increases or decreases the U.S. dollar equivalent of revenues generated and expenses incurred in those foreign currencies. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency financial statement amounts are remeasured into U.S. dollars. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in the consolidated results of operations. Restructuring and Severance Costs Restructuring and severance costs reflect charges resulting from cost reduction programs implemented by the Company. Restructuring and severance costs include exit costs, severance benefits pursuant to an on-going arrangement, voluntary termination compensation under a defined program, and any related pension curtailment and settlement charges. The Company recognizes expense for one-time benefits only after management has committed to a plan, the plan is sufficiently detailed to provide the number, classification, and location of employees to be terminated as well as the expected completion date, the plan has been sufficiently communicated to employees such that they are able to determine the type and amount of benefits they will receive if terminated, and it is unlikely that the plan will be significantly changed or withdrawn. If an employee is not required to render service beyond a minimum retention period, the Company recognizes expense once the aforementioned criteria have been met. If an employee is required to render service beyond a minimum retention period, the Company recognizes expense over the period that the employee is required to render future service. The Company recognizes expense for on-going benefit arrangements when the liability is reasonably estimable and considered probable. The Company recognizes expense for voluntary separation / early retirement when the employee delivers an irrevocable voluntary termination notice pursuant to a defined Company program. The Company recognizes other exit costs as incurred. Self-Insurance Programs The Company uses a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for workers’ compensation, general liability, property damage, director and officers’ liability, and vehicle liability. As part of its self-insurance program for certain risks, the Company created a wholly-owned captive insurance entity in 2007. At December 31, 2021, the captive insurance entity provides only property and general liability insurance, although it is licensed to also provide directors’ and officers’ insurance. The captive insurance entity had no amounts accrued for outstanding claims at December 31, 2021 and 2020. Certain investments held by the captive insurance entity are restricted primarily for the purpose of potential insurance claims. Such amounts are recorded in other noncurrent assets, and total $9,153 and $9,281 at December 31, 2021 and 2020, respectively, representing required statutory reserves of the captive insurance entity. Leases The Company leases buildings and machinery and equipment used for manufacturing and/or sales and administrative purposes. The Company is also party to various service, warehousing, and other agreements that it evaluates for potential embedded leases. Substantially all of the Company’s leases are structured and classified as operating leases. The Company leases assets in each region in which it operates. The Company’s leases are generally denominated in the currency of the leased assets' location, which may not be the functional currency of the subsidiary lessee. Accordingly, the Company remeasures its lease liability and recognizes a transactional gain/loss for leases denominated in currencies other than the functional currency of the subsidiary lessee. The Company recognizes right of use assets and lease liabilities for leases greater than twelve months in duration based on the contract consideration for lease components through the term of the lease and the applicable discount rate. Leases with a duration less than or equal to twelve months are considered short-term leases. The Company does not recognize right of use assets or lease liabilities for short-term leases and classifies the expense as short-term lease expense. Variable lease payments based on an index or rate are included in the right of use assets and lease liabilities based on the effective rates at lease commencement. Changes in the rates or indices do not impact the right of use asset or lease liability and are recognized as a component of lease expense in the consolidated statements of operations. Variable lease payments not based on an index or rate are not included in the initial right of use asset and lease liability and are recognized when incurred as a component of lease expense in the consolidated statements of operations. The Company has elected to not separate contract consideration for lease and non-lease components for its building leases. In addition to the noncancellable period of a lease, the Company includes periods covered by extension options it is reasonably certain to exercise, termination options that it is reasonably certain not to exercise, and extension and termination options controlled by the lessor in its determination of the lease term. The Company uses the rate implicit in the contract whenever possible when determining the applicable discount rate. When the implicit rate is not used, the Company employs a portfolio approach based on the duration of the lease. The portfolio lease rates are calculated monthly. No individual lease is considered significant and there are no leases that have not yet commenced that are considered significant. See Note 3. Recent Accounting Pronouncements Recent Accounting Guidance Adopted In August 2020, the Financial Accounting Standards Board ("FASB") Debt – Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity Reclassifications Certain prior year amounts have been reclassified to conform with current year presentation. Such reclassifications had no effect on reported net earnings attributable to Vishay stockholders, total assets, stockholders' equity, or the statements of cash flows.

Acquisition and Divestiture Activities [Abstract]
Acquisition and Divestiture Activities	Note 2 - Acquisition and Divestiture Activities As part of its growth strategy, the Company seeks to expand through targeted acquisitions of other manufacturers of electronic components that have established positions in major markets, reputations for product quality and reliability, and product lines with which the Company has substantial marketing and technical expertise. Year ended December 31, 2021 On December 31, 2021, the Company acquired substantially all of the assets of Barry Industries, a Massachusetts-based, privately-held manufacturer of resistive components for $20,847. Based on its estimate of their fair values pending finalization of the net working capital adjustment, the Company allocated $9,600 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on a preliminary estimation of their fair values at the date of acquisition, the Company recorded goodwill of $7,813 related to this acquisition. The inclusion of this acquisition did not have an impact on the Company's consolidated results for the year ended December 31, 2021. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. Year ended December 31, 2020 On October 1, 2020, the Company acquired the worldwide business and substantially all of the U.S. assets of Applied Thin-Film Products, a California-based, privately-held manufacturer of custom, build-to-print thin film substrates for the microwave, fiber optic, and life science industries. Concurrently, a Chinese subsidiary of Applied Thin-Film Products entered into an agreement to sell certain inventory and equipment to a subsidiary of Vishay, which was completed on June 30, 2021. The total acquisition price was $25,852. Based on its estimate of their fair values, the Company allocated $10,800 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $6,548 related to this acquisition. The results and operations of this acquisition have been included in the Resistors segment since October 1, 2020. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. Year ended December 31, 2019 On January 3, 2019, the Company acquired substantially all of the assets of Bi-Metallix, Inc. ("Bi-Metallix"), a U.S.-based, privately-held provider of electron beam continuous strip welding services for $11,862. The Company was a major customer of Bi-Metallix, and the acquired business has been vertically integrated into the Company's Resistors segment. Based on an estimate of their fair values, the Company allocated $2,900 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $3,324 related to this acquisition. The results and operations of this acquisition have been included in the Resistors segment since January 3, 2019. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. Had these acquisitions occurred as of the beginning of the periods presented in these consolidated financial statements, the pro forma statements of operations would not be materially different than the consolidated statements of operations presented.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities	Note 4 – Restructuring and Related Activities The Company places a strong emphasis on controlling its costs and combats general price inflation by continuously improving its efficiency and operating performance. When the ongoing cost containment activities are not adequate, the Company takes actions to maintain its cost competitiveness. The Company incurred significant restructuring costs in its past to reduce its cost structure. Historically, the Company's primary cost reduction technique was through the transfer of production from high-labor-cost countries to lower-labor-cost countries. Since 2013, the Company's cost reduction programs have primarily focused on reducing fixed costs, including selling, general, and administrative expenses. In 2019, the Company announced global cost reduction and management rejuvenation programs as part of its continuous efforts to improve efficiency and operating performance. The programs were primarily designed to reduce manufacturing fixed costs and selling, general, and administrative costs company-wide, and provide management rejuvenation. These programs are fully implemented. The Company incurred charges of $24,882, primarily related to cash severance costs, to implement these programs. The following table summarizes the activity to date related to this program: Expense recorded in 2019 $ 24,139 Cash paid (1,330 ) Foreign currency translation 35 Balance at December 31, 2019 $ 22,844 Expense recorded in 2020 743 Cash paid (10,813 ) Foreign currency translation 683 Balance at December 31, 2020 $ 13,457 Cash paid (11,474 ) Foreign currency translation (133 ) Balance at December 31, 2021 $ 1,850 Severance payment terms vary by country, but generally are paid in a lump sum at cessation of employment. Some payments are made over an extended period. The current portion of the liability is $ and is included in other accrued expenses in the accompanying consolidated balance sheet. The non-current portion of the liability is $ and is included in other liabilities in the accompanying consolidated balance sheet.

Income Taxes

Income Taxes [Abstract]
Income Taxes	Note 5 – Income Taxes Changes in Tax Laws and Regulations Israel Effective November 15, 2021, Israel enacted changes in its tax laws. The Company has historically benefited from tax incentive programs offered by the Israeli government, including the generation of income not subject to current income tax. Any tax-exempt earnings generated under these programs would incur an additional “claw-back” tax at approximately 11.1% if they were distributed or invested outside of Israel, in addition to normal withholding taxes on earnings distributed from Israel. Otherwise, taxes on such earnings were indefinitely deferred. The change in tax law enacted on November 15, 2021 provided companies with an election to currently pay a reduced claw-back rate of as low as 6% upon meeting certain conditions, with the ability to distribute or invest those amounts outside of Israel at any time in the future. The Company will elect to pay taxes on all previously untaxed earnings at the reduced 6% claw-back rate. As a direct result of this change in tax law, the Company made the determination during the fourth fiscal quarter of 2021 that substantially all unremitted foreign earnings in Israel are no longer permanently reinvested. The Company recorded additional tax expense of $53,316 during the fourth fiscal quarter of 2021 to accrue the claw-back tax on applicable earnings and withholding taxes necessary to distribute these approximately $385,000 of accumulated earnings to the United States. United States On December 22, 2017, the Tax Cuts and Jobs Act (the "TCJA") was enacted in the United States. Under previous law, companies could indefinitely defer U.S. income taxation on unremitted foreign earnings. The TCJA imposed a one-time transition tax on deferred foreign earnings, payable in defined increments over eight years. Installments of $14,757 were paid in each of 2021, 2020, 2019, and 2018. The Company expects future installment payments as follows: 2022 $ 14,757 2023 27,669 2024 36,893 2025 46,119 The U.S. Internal Revenue Service continues to issue regulations to address the provisions of the TCJA. During 2021, the Company amended tax returns for 2018 and 2019 and recognized tax benefits of $8,276 as a result of changes in tax regulations, by making an election regarding Global Intangible Low-Taxed Income (“GILTI”). The Company has elected to account for GILTI tax in the period in which it is incurred and, therefore, does not provide any deferred taxes in the consolidated financial statements at December 31, 2021, 2020, or 2019. The Company repatriated $104,091 and $188,742 to the United States in 2020 and 2019, pursuant to a repatriation program initiated in response to the enactment of the TCJA. Tax expense for these repatriation transactions was substantially recorded in 2017 upon enactment of the TCJA. There are amounts of unremitted foreign earnings in countries other than Israel, which continue to be reinvested indefinitely, and the Company has made no provision for incremental foreign income taxes and withholding taxes payable to foreign jurisdictions related to these amounts. Determination of the amount of the unrecognized deferred foreign tax liability for these amounts is not practicable because of the complexities associated with its hypothetical calculation. Income (loss) before taxes consists of the following components: Years ended December 31, 2021 2020 2019 Domestic $ 62,921 $ (25,884 ) $ (10,992 ) Foreign 371,689 184,212 237,290 $ 434,610 $ 158,328 $ 226,298 Significant components of income taxes are as follows: Years ended December 31, 2021 2020 2019 Current: Federal $ 2,336 $ 7,327 $ 9,137 State and local 466 218 415 Foreign 82,258 55,399 113,779 85,060 62,944 123,331 Deferred: Federal 554 (6,068 ) (13,731 ) State and local 383 (538 ) (802 ) Foreign 49,676 (21,793 ) (47,290 ) 50,613 (28,399 ) (61,823 ) Total income tax expense $ 135,673 $ 34,545 $ 61,508 Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows: December 31, 2021 2020 Deferred tax assets: Pension and other retiree obligations $ 50,069 $ 53,585 Inventories 17,168 19,539 Net operating loss carryforwards 115,200 124,251 Tax credit carryforwards 76,213 85,651 Other accruals and reserves 29,332 31,347 Total gross deferred tax assets 287,982 314,373 Less valuation allowance (186,204 ) (206,950 ) 101,778 107,423 Deferred tax liabilities: Property and equipment (1,514 ) (1,604 ) Tax deductible goodwill (5,412 ) (4,708 ) Earnings not permanently reinvested (67,172 ) - Convertible debentures - (12,777 ) Other - net (1,646 ) (1,656 ) Total gross deferred tax liabilities (75,744 ) (20,745 ) Net deferred tax assets (liabilities) $ 26,034 $ 86,678 The Company makes significant judgments regarding the realizability of its deferred tax assets (principally net operating losses and tax credits). The carrying value of deferred tax assets is based on the Company’s assessment that it is more likely than not that the Company will realize these assets after consideration of all available positive and negative evidence. As of December 31, 2021, the Company has generated an excess U.S. foreign tax credit of $58,673. Because the Company does not anticipate sufficient U.S. foreign source income during the carryforward period, the Company has not recognized the benefit of the carryforward as of December 31, 2021. A reconciliation of income tax expense at the U.S. federal statutory income tax rate to actual income tax provision is as follows: Years ended December 31, 2021 2020 2019 Tax at statutory rate $ 91,268 $ 33,249 $ 47,523 State income taxes, net of U.S. federal tax benefit 671 (252 ) (301 ) Effect of foreign operations 5,521 (9,896 ) 9,242 Tax on earnings not permanently reinvested 54,648 4,227 6,256 Unrecognized tax benefits 1,318 4,351 5,584 Change in valuation allowance on non-U.S. deferred tax assets (5,714 ) - - Foreign income taxable in the U.S. 9,532 7,675 10,691 Foreign tax credit (9,477 ) (3,520 ) (4,601 ) Foreign tax credit carryforward utilized (9,207 ) - - U.S. Base Erosion Anti-Abuse Tax 9,134 750 2,851 Change in U.S. tax regulations (8,276 ) - - Deferred tax rate impact of corporate reorganization - - (12,121 ) Other (3,745 ) (2,039 ) (3,616 ) Total income tax expense $ 135,673 $ 34,545 $ 61,508 Vishay operates in a global environment with significant operations in various locations outside the United States. Accordingly, the consolidated income tax rate is a composite rate reflecting our earnings and the applicable tax rates in the various locations where we operate. Part of Vishay's historical strategy has been to achieve cost savings through the transfer and expansion of manufacturing operations to countries where it can take advantage of lower labor costs and available tax and other government-sponsored incentives. With the reduction in the U.S. statutory rate to 21% beginning January 1, 2018, Vishay expects that its effective tax rate will be higher than the U.S. statutory rate, excluding unusual transactions. Historically, the effective tax rates were generally less than the U.S. statutory rate of 35% primarily because of earnings in foreign jurisdictions. Income tax expense for the years ended December 31, 2021, 2020, and 2019 includes certain discrete tax items for changes in uncertain tax positions, valuation allowances, tax rates, and other related items. These items total $39,326, $1,998, and $799 (tax benefit) in 2021, 2020, and 2019, respectively. For the year ended December 31, 2021, the discrete items include $ of tax expense recognized to accrue the claw-back and withholding taxes to repatriate unremitted foreign earnings from Israel, a $ For the year ended December 31, 2020, the discrete items include a tax benefit of $1,563 resulting from the early extinguishment of convertible senior debentures, reflecting the reduction in deferred tax liabilities related to the special tax attributes of the debentures and $190 (tax benefit) of adjustments to remeasure deferred taxes related to the cash repatriation program described above, and $3,751 of tax expense for changes in uncertain tax positions. For the year ended December 31, 2019, the discrete items include $ of tax expense related to a tax-basis foreign exchange gain on the settlement of an intercompany loan, which previously had been accounted for at the historical foreign exchange rate (akin to an equity contribution) because the debtor entity did not have the intent or ability to repay such intercompany loan. Currency translation adjustments were recorded in accumulated other comprehensive income, and were not included in U.S. GAAP pre-tax income. The Company’s cash repatriation activity resulted in the ability to repay such intercompany loan. Upon settlement of this intercompany loan, the foreign entity realized a taxable gain. Discrete tax items also include At December 31, 2021, the Company had the following significant net operating loss carryforwards for tax purposes: Expires Austria $ 13,211 No expiration Belgium 159,563 No expiration Israel 10,368 No expiration Italy 12,638 No expiration Japan 7,476 2023 2030 Netherlands 10,552 No expiration The Republic of China (Taiwan) 16,750 2026 2028 California 19,650 2028 2036 Pennsylvania 601,818 2022 2041 At December 31, 2021, the Company had the following significant tax credit carryforwards available: Expires U.S. Foreign Tax Credit $ 58,673 2028 2031 California Research Credit 17,484 No expiration Net income taxes paid were $79,106, $69,706, and $185,654 for the years ended December 31, 2021, 2020, and 2019, respectively. Net income taxes paid for the years ended December 31, 2020 and 2019 include $16,258 and $38,814, respectively, for TCJA repatriation activity and $14,757 in each period for the TCJA transition tax. The following table summarizes changes in the liabilities associated with unrecognized tax benefits: Years ended December 31, 2021 2020 2019 Balance at beginning of year $ 40,652 $ 36,868 $ 21,241 Addition based on tax positions related to the current year 141 663 2,383 Addition based on tax positions related to prior years 1,037 8,358 16,190 Currency translation adjustments (523 ) 1,361 1,211 Reduction based on tax positions related to prior years (13,154 ) (3,152 ) - Reduction for settlements (982 ) (3,446 ) (3,121 ) Reduction for lapses of statute of limitation (452 ) - (1,036 ) Balance at end of year $ 26,719 $ 40,652 $ 36,868 All of the unrecognized tax benefits of $26,719 and $40,652, as of December 31, 2021 and 2020, respectively, would reduce the effective tax rate if recognized. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. At December 31, 2021 and 2020, the Company had accrued interest and penalties related to the unrecognized tax benefits of $3,747 and $3,239, respectively. During the years ended December 31, 2021, 2020, and 2019, the Company recognized $591, $128, and $1,201, respectively, in interest and penalties. The Company and its subsidiaries file U.S. federal income tax returns, as well as tax returns in multiple states and foreign jurisdictions. The Company's During the years ended December 31, 2021, 2020, and 2019, certain tax examinations were concluded and certain statutes of limitations lapsed. The tax provision for those years includes adjustments related to the resolution of these matters, as reflected in the table above. The tax returns of significant non-U.S. subsidiaries currently under examination are located in the following jurisdictions: Germany (2013 through 2016), India (2004 through 2017), Israel (2018 and 2019), Singapore (2015 through 2019), and the Republic of China (Taiwan) (2019). The Company and its subsidiaries also file income tax returns in other taxing jurisdictions in the U.S. and around the world, many of which are still open to examination. The timing of the resolution of income tax examinations is highly uncertain, as are the amounts and timing of tax payments that result from such examinations. These events could cause large fluctuations in the balance sheet classification of current and non-current unrecognized tax benefits. The Company believes that in the next 12 months it is reasonably possible that certain income tax examinations will conclude or the statutes of limitation on certain income tax periods open to examination will expire, or both. Given the uncertainties described above, the Company can only determine an estimate of potential decreases in unrecognized tax benefits ranging from $3,783 to $16,449.

Long-Term Debt [Abstract]
Long-Term Debt	Note 6 – Long-Term Debt Long-term debt consists of the following: December 31, 2021 December 31, 2020 Credit facility $ - $ - Convertible senior notes, due 2025 465,344 406,268 Convertible senior debentures, due 2040 - 130 Deferred financing costs (9,678 ) (11,512 ) 455,666 394,886 Less current portion - - $ 455,666 $ 394,886 Credit Facility The Company maintains a credit agreement with a consortium of banks led by JPMorgan Chase Bank, N.A., as administrative agent, and the lenders (the "Credit Facility"), which provides an aggregate commitment of $ of revolving loans available until . The Credit Facility also provides for the ability of Vishay to request up to $ of incremental facilities, subject to the satisfaction of certain conditions, which could take the form of additional revolving commitments, incremental “term loan A” or “term loan B” facilities, or incremental equivalent debt. Borrowings under the Credit Facility bear interest at LIBOR plus an interest margin. The applicable interest margin is based on the Company's leverage ratio. Based on the Company's current leverage ratio, borrowings bear interest at LIBOR plus . The Company also pays a commitment fee, also based on its leverage ratio, on undrawn amounts. The undrawn commitment fee, based on the Company's current leverage ratio, is per annum. The Credit Facility allows an unlimited amount of defined “Investments,” which include certain intercompany transactions and acquisitions, provided the Company's pro forma leverage ratio is equal to or less than to 1.00. If the Company's pro forma leverage ratio is greater than to 1.00, such Investments are subject to certain limitations. The Credit Facility also allows an unlimited amount of defined "Restricted Payments," which include cash dividends and share repurchases, provided the Company's pro forma leverage ratio is equal to or less than to 1.00. If the Company's pro forma leverage ratio is greater than to 1.00, the Credit Facility allows such payments up to $ per annum (subject to a cap of $ for the term of the facility, with up to $ of any unused amount of the $ per annum base available for use in the next succeeding calendar year). Borrowings under the Credit Facility are secured by a lien on substantially all assets, including accounts receivable, inventory, machinery and equipment, and general intangibles (but excluding real estate, intellectual property registered or licensed solely for use in, or arising solely under the laws of, any country other than the United States, assets located solely outside of the United States and deposit and securities accounts), of the Company and certain significant subsidiaries located in the United States, and pledges of stock in certain significant domestic and foreign subsidiaries; and are guaranteed by certain significant subsidiaries. The Credit Facility limits or restricts the Company and its subsidiaries, from, among other things, incurring indebtedness, incurring liens on its respective assets, making investments and acquisitions (assuming the Company’s pro forma leverage ratio is greater than to 1.00), making asset sales, and paying cash dividends and making other restricted payments (assuming the Company's pro forma leverage ratio is greater than to 1.00), and requires the Company to comply with other covenants, including the maintenance of specific financial ratios. The Credit Facility also contains customary events of default, including, but not limited to, failure to pay principal or interest, failure to pay or default under other material debt, material misrepresentation or breach of warranty, violation of certain covenants, a change of control, the commencement of bankruptcy proceedings, the insolvency of the Company or certain of its significant subsidiaries, and the rendering of a judgment in excess of $ against the Company or its subsidiaries. Upon the occurrence of an event of default under the Credit Facility, the Company's obligations under the credit facility may be accelerated and the lending commitments under the credit facility may be terminated. At December 31, 2021 and 2020, there was $748,931 and $748,690, respectively, available under the Credit Facility. Letters of credit totaling $1,069 and $1,310 were outstanding at December 31, 2021 and 2020, respectively. Convertible Debt Instruments The following table summarizes some key facts and terms regarding the outstanding convertible senior notes due 2025 as of December 31, 2021: Due 2025 Issuance date June 12, 2018 Maturity date June 15, 2025 Principal amount $ 465,344 Cash coupon rate (per annum) 2.25 % Nonconvertible debt borrowing rate at issuance (per annum) 5.50 % Conversion rate effective December 16, 2021 (per $1 principal amount) 31.9492 Effective conversion price effective December 16, 2021 (per share) $ 31.30 130 $ 40.69 Prior to December 15, 2024, the holders of the convertible senior notes due 2025 may convert their notes only under the following circumstances: (1) the sale price of Vishay common stock reaches 130% of the conversion price for a specified period; (2) the trading price of the notes falls below 98% of the product of the sale price of Vishay's common stock and the conversion rate for a specified period; or (3) upon the occurrence of specified corporate transactions. The convertible senior notes due 2025 are not currently convertible. Pursuant to the Supplemental Indenture governing the convertible senior notes due 2025, at the direction of its Board of Directors, Vishay has fixed the “Specified Dollar Amount” (as defined in the Indenture) that shall apply to all future conversions of notes at $1 cash per $1 principal amount. The fixing of the Specified Dollar Amount requires Vishay to satisfy its conversion obligations by paying cash with respect to such Specified Dollar Amount. The quarterly cash dividend program of the Company results in adjustments to the conversion rate and effective conversion price for the convertible senior notes due 2025 effective as of the ex-dividend date of each cash dividend. The conversion rate and effective conversion price for the convertible senior notes due 2025 is adjusted for quarterly cash dividends to the extent such dividends exceed $ per share of common stock. Effective January 1, 2021, Vishay adopted ASU No. 2020-06. Prior to the adoption of ASU No. 2020-06, the Company separately accounted for the liability and equity components of convertible debt instruments that may be settled in cash in a manner that reflects the Company’s nonconvertible debt borrowing rate. The liability component at issuance was recognized at fair value, based on the fair value of a similar instrument that did not have a conversion feature. A discount was recorded if debt instruments are issued at a coupon rate which is below the rate of a similar instrument that did not have a conversion feature at issuance. The equity component was based on the excess of the principal amount of the debt instruments over the fair value of the liability component, after adjusting for an allocation of debt issuance costs and the deferred tax impact, and was recorded as capital in excess of par. Debt discounts were amortized as additional non-cash interest expense over the expected life of the debt. Upon adoption of ASU No. 2020-06, Vishay derecognized the bifurcated equity component, debt discount, and deferred taxes and remeasured the deferred financing costs associated with its convertible debt instruments. See Note 1. The carrying value of Vishay's convertible debt instruments is now equal to the outstanding principal amount and interest expense is now equal to the cash interest paid. The remeasured deferred financing costs continue to be recognized as non-cash interest expense. The carrying value of the convertible senior notes due 2025 was $465,344 as of December 31, 2021. The carrying value of the liability and equity components of the convertible debt instruments prior to the adoption of ASU No. 2020-06 are reflected in the Company’s consolidated balance sheet as follows: Principal amount of the convertible debt Unamortized discount Carrying value of liability component Equity component (including temporary equity) - net carrying value December 31, 2020 Convertible senior notes due 2025 $ 465,344 (59,076 ) $ 406,268 $ 66,127 Convertible senior debentures due 2040 $ 300 (170 ) $ 130 $ 121 Total $ 465,644 $ (59,246 ) $ 406,398 $ 66,248 Interest expense related to the convertible debt instruments is reflected on the accompanying consolidated statements of operations for the years ended December 31: Contractual coupon interest Non-cash amortization of debt discount Other non-cash interest expense Total interest expense related to the debentures 2021 Convertible senior notes due 2025 $ 10,470 - 1,733 $ 12,203 2020 Convertible senior notes due 2025 $ 12,097 13,118 1,623 $ 26,838 Convertible senior debentures $ 88 43 - $ 131 Total $ 12,185 $ 13,161 $ 1,623 $ 26,969 2019 Convertible senior notes due 2025 $ 13,500 13,925 1,816 $ 29,241 Convertible senior debentures 498 221 (35 ) 684 Total $ 13,998 $ 14,146 $ 1,781 $ 29,925 The Company used cash to repurchase $1,010, $16,188 and $2,168 principal amounts of convertible senior debentures due 2040, due 2041, and due 2042, respectively, in 2019. The net carrying value of the debentures repurchased were $417, $6,282, and $924, respectively. In accordance with the then-current authoritative accounting guidance for convertible debentures, the aggregate repurchase payment of $27,863 was allocated between the liability ($9,568) and equity (including temporary equity, $18,295) components of the convertible debentures, using the Company's nonconvertible debt borrowing rate at the time of the repurchase. As a result, the Company recognized a loss on extinguishment of convertible debentures of $2,030, including the write-off of a portion of unamortized debt issuance costs. The Company used cash to repurchase $134,656 principal amount of convertible senior notes due 2025 in 2020. The net carrying value of the notes repurchased was $115,978. In accordance with the then-current authoritative accounting guidance for convertible debt, the aggregate repurchase payments of $128,328 were allocated between the liability ($118,587) and equity ($9,741) components of the convertible notes, using the Company's nonconvertible debt borrowing rate at the time of the repurchases. As a result, the Company recognized a loss on extinguishment of convertible notes of $4,600, including the write-off of unamortized debt issuance costs. The Company used cash to repurchase $16,890 principal amount of convertible senior debentures due 2041 in 2020. The net carrying value of the debentures repurchased was $6,715. In accordance with the then-current authoritative accounting guidance for convertible debt, the aggregate repurchase payment of $23,355 was allocated between the liability ($10,075) and equity ($13,280) components of the convertible debentures, using the Company's nonconvertible debt borrowing rate at the time of the repurchase. As a result, the Company recognized a loss on extinguishment of convertible debentures of $3,473, including the write-off of unamortized debt issuance costs. Vishay redeemed the remaining $300 principal amount of convertible senior debentures due 2040 on February 4, 2021. The redemption price was paid in cash and was equal to 100% of the principal amount plus accrued but unpaid interest to, but excluding February 4, 2021. The convertible senior debentures due 2040, due 2041, and due 2042 have been fully repurchased. Other Borrowings Information The Credit Facility, of which no amounts were drawn as of December 31, 2021, expires in 2024. The convertible senior notes mature in 2025. At December 31, 2021 and 2020, the Company had committed and uncommitted short-term credit lines with various U.S. and foreign banks aggregating approximately $1,000 and $6,000, respectively, with substantially no amounts borrowed. Interest paid was $14,177, $15,450, and $16,177 for the years ended December 31, 2021, 2020, and 2019, respectively. See Note 18 for further discussion on the fair value of the Company’s long-term debt.

Stockholders' Equity [Abstract]
Stockholders' Equity	Note 7 – Stockholders’ Equity The Company’s Class B common stock carries 10 votes per share while the common stock carries 1 vote per share. Class B shares are transferable only to certain permitted transferees while the common stock is freely transferable. Class B shares are convertible on a one-for-one basis at any time into shares of common stock. Transfers of Class B shares other than to permitted transferees result in the automatic conversion of the Class B shares into common stock. The Board of Directors may only declare dividends or other distributions with respect to the common stock or the Class B common stock if it grants such dividends or distributions in the same amount per share with respect to the other class of stock. Stock dividends or distributions on any class of stock are payable only in shares of stock of that class. Shares of either common stock or Class B common stock cannot be split, divided, or combined unless the other is also split, divided, or combined equally. Cash dividends were paid quarterly in 2021 and 2020. The Credit Facility also allows an unlimited amount of defined "Restricted Payments," which include cash dividends and share repurchases, provided the Company's pro forma leverage ratio is equal to or less than 2.50 to 1.00. If the Company's pro forma leverage ratio is greater than 2.50 to 1.00, the Credit Facility allows such payments up to $100,000 per annum (subject to a cap of $300,000 for the term of the facility, with up to $25,000 of any unused amount of the $100,000 per annum base available for use in the next succeeding calendar year). At December 31, 2021, the Company had reserved shares of common stock for future issuance as follows: Restricted stock units outstanding 877,000 Phantom stock units outstanding 212,000 2007 Stock Incentive Program - available to grant 1,975,000 Convertible senior notes, due 2025 14,867,369 Conversion of Class B common stock 12,097,148 30,028,517

Impact of the COVID-19 Pandemic The Company's operations have been impacted by the "COVID-19" pandemic, particularly in 2020 when some manufacturing facilities were temporarily closed and some were operating at levels less than full capacity. The Company incurred incremental costs separable from normal operations that are directly related to the outbreak and containment efforts, primarily wages paid to manufacturing employees during government-mandated shut-downs, additional wages and hardship allowances for working during lockdown periods, additional costs of cleaning and disinfecting facilities, costs of additional safety equipment for employees, and temporary housing for employees due to travel restrictions, which were partially offset by government subsidies. The net impact of the costs and subsidies are reported as cost of products sold of $4,563 and selling, general, and administrative benefits of $1,451 based on employee function on the consolidated statement of operations for the year ended December 31, 2020. Directly attributable costs of the pandemic are no longer incremental and have become part of normal operations. Accordingly, in 2021, they are considered normal operating costs. The Company's insurance coverages generally exclude losses incurred due to pandemics. Any amounts that may be received will not be recognized until all contingencies are settled.

Pensions and Other Postretirement Benefits [Abstract]
Pensions and Other Postretirement Benefits	Note 11 – Pensions and Other Postretirement Benefits The Company maintains various retirement benefit plans. GAAP requires employers to recognize the funded status of a benefit plan, measured as the difference between plan assets at fair value and the benefit obligation, in its balance sheet. The recognition of the funded status on the balance sheet requires employers to recognize actuarial items (such as actuarial gains and losses, prior service costs, and transition obligations) as a component of other comprehensive income, net of tax. The following table summarizes amounts recorded on the accompanying consolidated balance sheets associated with these various retirement benefit plans: December 31, 2021 2020 Included in "Other assets": Non-U.S. pension plans $ 3,145 $ 312 Total included in other assets $ 3,145 $ 312 Included in "Payroll and related expenses": U.S. pension plans $ (35 ) $ (35 ) Non-U.S. pension plans (7,602 ) (8,314 ) U.S. other postretirement plans (975 ) (929 ) Non-U.S. other postretirement plans (696 ) (475 ) Total included in payroll and related expenses $ (9,308 ) $ (9,753 ) Accrued pension and other postretirement costs: U.S. pension plans $ (45,578 ) $ (45,529 ) Non-U.S. pension plans (197,796 ) (225,473 ) U.S. other postretirement plans (6,636 ) (6,794 ) Non-U.S. other postretirement plans (7,086 ) (8,035 ) Other retirement obligations (14,576 ) (14,282 ) Total accrued pension and other postretirement costs $ (271,672 ) $ (300,113 ) Accumulated other comprehensive loss: U.S. pension plans $ 9,403 $ 10,709 Non-U.S. pension plans 72,437 94,480 U.S. other postretirement plans 837 344 Non-U.S. other postretirement plans 1,706 2,119 Total accumulated other comprehensive loss* $ 84,383 $ 107,652 * - Amounts included in accumulated other comprehensive loss are presented in this table pre-tax. Defined Benefit Pension Plans U.S. Pension Plans The Company maintained several defined benefit pension plans which covered most full-time U.S. employees. These included pension plans which are “qualified” under the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Internal Revenue Code, and “non-qualified” pension plans which provide defined benefits primarily to U.S. employees whose benefits under the qualified pension plan would be limited by ERISA and the Internal Revenue Code. The Company’s principal qualified U.S. pension plan (the Vishay Retirement Plan) was frozen effective January 1, 2009 and terminated in 2016. The Company’s principal non-qualified U.S. pension plan (the Vishay Non-qualified Retirement Plan) was a contributory pension plan designed to provide similar defined benefits to covered U.S. employees whose benefits under the Vishay Retirement Plan were limited by the Internal Revenue Code. The Vishay Non-qualified Retirement Plan was similar in construction to the Vishay Retirement Plan, except that the plan is not qualified under the Internal Revenue Code. The Vishay Non-qualified Retirement Plan, like all non-qualified plans, is considered to be unfunded. The Company maintains a non-qualified trust, referred to as a “rabbi” trust, to fund benefit payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets. Assets held in trust related to the non-qualified pension plan were $27,604 and $29,157 at December 31, 2021 and 2020, respectively. In 2008, the Company adopted amendments to the Vishay Non-Qualified Retirement Plan such that effective January 1, 2009, the plan was frozen. Pursuant to these amendments, no new employees may participate in the plans, no further participant contributions were required or permitted, and no further benefits shall accrue after December 31, 2008. Benefits accumulated as of December 31, 2008 will be paid to employees upon or following retirement, and the Company will likely need to make additional cash contributions to the rabbi trust to fund this accumulated benefit obligation. The Company also maintains other pension plans which provide supplemental defined benefits primarily to former U.S. employees whose benefits under qualified pension plans were limited by the Internal Revenue Code. These non-qualified plans are all non-contributory plans, and are considered to be unfunded. In 2004, the Company entered into an employment agreement with Dr. Felix Zandman, its Executive Chairman and then-Chief Executive Officer. Pursuant to this agreement, the Company is providing an annual retirement benefit of approximately $614 to his surviving spouse. The Company maintains a non-qualified trust, referred to as a “rabbi” trust, to fund benefit payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets. Assets held in trust related to this non-qualified pension plan were $630 and $1,243 at December 31, 2021 and 2020, respectively. Non-U.S. Pension Plans The Company provides pension and similar benefits to employees of certain non-U.S. subsidiaries consistent with local practices. Pension benefits earned are generally based on years of service and compensation during active employment. The following table sets forth a reconciliation of the benefit obligation, plan assets, and funded status related to U.S. and non-U.S. pension plans: December 31, 2021 December 31, 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Change in benefit obligation: Benefit obligation at beginning of year $ 45,564 $ 307,809 $ 42,383 $ 283,561 Service cost - 4,693 - 4,382 Interest cost 1,016 2,968 1,366 3,783 Plan amendments - 490 - 1,015 Actuarial (gains) losses 870 (7,816 ) 3,623 10,920 Benefits paid (1,837 ) (14,773 ) (1,808 ) (17,737 ) Curtailments and settlements - (34 ) - (464 ) Currency translation - (15,164 ) - 22,349 Benefit obligation at end of year $ 45,613 $ 278,173 $ 45,564 $ 307,809 Change in plan assets: Fair value of plan assets at beginning of year $ - $ 74,334 $ - 73,629 Actual return on plan assets - 2,792 - 2,811 Company contributions 1,837 13,095 1,808 12,149 Benefits paid (1,837 ) (14,773 ) (1,808 ) (17,737 ) Currency translation - 472 - 3,482 Fair value of plan assets at end of year $ - $ 75,920 $ - $ 74,334 Funded status at end of year $ (45,613 ) $ (202,253 ) $ (45,564 ) $ (233,475 ) The plan assets are stated at fair value.

The estimated actuarial items for the defined benefit pensions plans that will be amortized from accumulated other comprehensive loss into net periodic pension cost during 2022 is $7,200. The following weighted average assumptions were used to determine benefit obligations at December 31 of the respective years: 2021 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Discount rate 2.50 % 1.19 % 2.25 % 1.02 % Rate of compensation increase 0.00 % 2.07 % 0.00 % 2.02 % The following weighted average assumptions were used to determine the net periodic pension costs: Years ended December 31, 2021 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Discount rate 2.25 % 1.02 % 3.25 % 1.40 % Rate of compensation increase 0.00 % 2.02 % 0.00 % 2.24 % Expected return on plan assets 0.00 % 2.37 % 0.00 % 2.35 % The plans’ expected return on assets is based on management’s expectations of long-term average rates of return to be achieved by the underlying investment portfolios. In establishing this assumption, management considers historical and expected returns for the asset classes in which the plans are invested, advice from pension consultants and investment advisors, and current economic and capital market conditions. The investment mix between equity securities and fixed income securities is based upon achieving a desired return, balancing higher return, more volatile equity securities, and lower return, less volatile fixed income securities and is adjusted for the expected duration of the obligation and the funded status of the plan. Investment allocations are made across a range of securities, maturities and credit quality. The Company’s non-U.S. defined benefit plan investments are based on local laws and customs. Most plans invest in cash and local government fixed income securities, although plans in certain countries have investments in equity securities. The plans do not invest in securities of Vishay or its subsidiaries. Negative investment returns could ultimately affect the funded status of the plans, requiring additional cash contributions. See Note 18 for further information on the fair value of the plan assets by asset category. Estimated future benefit payments are as follows: U.S. Plans Non-U.S. Plans 2022 $ 1,940 $ 18,924 2023 8,859 16,333 2024 3,376 16,061 2025 10,029 17,124 2026 3,247 19,069 2027-2031 9,993 78,158 The Company’s anticipated 2022 contributions for defined benefit pension plans will approximate the expected benefit payments disclosed above. Other Postretirement Benefits In the U.S., the Company maintains unfunded non-pension postretirement plans, including medical benefits for certain executives and their surviving spouses, which are funded as costs are incurred. The Company also maintains two unfunded non-pension postretirement plans at two European subsidiaries. The following table sets forth a reconciliation of the benefit obligation, plan assets, and accrued benefit cost related to U.S. and non-U.S. non-pension defined benefit postretirement plans: December 31, 2021 December 31, 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Change in benefit obligation: Benefit obligation at beginning of year $ 7,723 $ 8,510 $ 7,689 $ 8,109 Service cost 102 278 112 284 Interest cost 163 42 236 64 Actuarial (gains) losses 545 (77 ) 550 35 Benefits paid (922 ) (319 ) (864 ) (706 ) Currency translation - (652 ) - 724 Benefit obligation at end of year $ 7,611 $ 7,782 $ 7,723 $ 8,510 Fair value of plan assets at end of year $ - $ - $ - $ - Funded status at end of year $ (7,611 ) $ (7,782 ) $ (7,723 ) $ (8,510 ) Amounts recognized in the accompanying consolidated balance sheets consist of the following: December 31, 2021 December 31, 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Accrued benefit liability - current $ (975 ) $ (696 ) $ (929 ) $ (475 ) Accrued benefit liability - non-current (6,636 ) (7,086 ) (6,794 ) (8,035 ) Accumulated other comprehensive income 837 1,706 344 2,119 $ (6,774 ) $ (6,076 ) $ (7,379 ) $ (6,391 ) Actuarial items consist of the following: December 31, 2021 December 31, 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Unrecognized net actuarial loss (gain) $ 837 $ 1,706 $ 344 $ 2,119 $ 837 $ 1,706 $ 344 $ 2,119 The following table sets forth the components of net periodic benefit cost: Years ended December 31, 2021 2020 2019 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Service cost $ 102 $ 278 $ 112 $ 284 $ 157 $ 284 Interest cost 163 42 236 64 286 123 Amortization of actuarial (gains) losses 53 116 26 132 (138 ) 107 Curtailment and settlement losses - 67 - 177 - - Net periodic benefit cost (benefit) $ 318 $ 503 $ 374 $ 657 $ 305 $ 514 The estimated actuarial items for the other postretirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2022 are not material. The following weighted average assumptions were used to determine benefit obligations at December 31 of the respective years: 2021 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Discount rate 2.50 % 0.80 % 2.25 % 0.54 % Rate of compensation increase 0.00 % 2.88 % 0.00 % 2.87 % The following weighted average assumptions were used to determine the net periodic benefit costs: Years ended December 31, 2021 2020 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Discount rate 2.25 % 0.54 % 3.25 % 0.81 % Rate of compensation increase 0.00 % 2.87 % 0.00 % 2.87 % The impact of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit cost and postretirement benefit obligation is not material. Estimated future benefit payments are as follows: U.S. Plans Non-U.S. Plans 2022 $ 975 $ 696 2023 871 255 2024 802 239 2025 706 476 2026 619 169 2027-2031 2,131 3,753 As the plans are unfunded, the Company’s anticipated contributions for 2022 are equal to its estimated benefits payments. Other Retirement Obligations The Company participates in various other defined contribution and government-mandated retirement plans based on local law or custom. The Company periodically makes required contributions for certain of these plans, whereas other plans are unfunded retirement bonus plans which will be paid at the employee's retirement date. At December 31, 2021 and 2020, the accompanying consolidated balance sheets include $14,576 and $14,282, respectively, within accrued pension and other postretirement costs related to these plans. The Company’s U.S. employees are eligible to participate in a 401(k) savings plan, which provides for Company matching contributions. The Company’s matching expense for the plans was $6,557, $6,363, and $6,481 for the years ended December 31, 2021, 2020, and 2019, respectively. No material amounts are included in the accompanying consolidated balance sheets at December 31, 2021 and 2020 related to unfunded 401(k) contributions. Certain key employees participate in a deferred compensation plan. During the years ended December 31, 2021, 2020, and 2019, these employees could defer a portion of their compensation until retirement, or elect shorter deferral periods. The Company maintains a liability within other noncurrent liabilities on its consolidated balance sheets related to these deferrals. The Company maintains a non-qualified trust, referred to as a “rabbi” trust, to fund payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets. Assets held in trust related to the deferred compensation plan at December 31, 2021 and 2020 were approximately $31,453 and $27,491, respectively.

The 2007 Program permits the grant of up to 6,500,000 shares of restricted stock, unrestricted stock, RSUs, stock options, and phantom stock units, to officers, employees, and non-employee directors of the Company. Such instruments are available for grant until May 20, 2024. At December 31, 2021, the Company has reserved 1,975,000 shares of common stock for future grants of equity awards pursuant to the 2007 Program. If any outstanding awards are forfeited by the holder or cancelled by the Company, the underlying shares would be available for regrant to others. Restricted Stock Units Each RSU entitles the recipient to receive a share of common stock when the RSU vests.

The number of performance-based RSUs scheduled to vest increases ratably based on the achievement of defined performance criteria between the established target and maximum levels. RSUs with performance-based vesting criteria are expected to vest as follows (number of RSUs in thousands) Vesting Date Expected to Vest Not Expected to Vest Total January 1, 2022** 174 - 174 January 1, 2023 152 - 152 January 1, 2024 165 - 165 ** The performance vesting criteria for the performance-based RSUs with a vesting date of January 1, 2022 were achieved. In the event of (i) any termination (other than for cause) after attaining retirement age (as defined in the respective executive's employment arrangement), the executive's outstanding RSUs shall immediately vest and the outstanding performance-based RSUs shall vest on their normal vesting date to the extent applicable performance criteria are realized; and (ii) a change of control of Vishay, all of such executive’s outstanding RSUs and performance-based RSUs shall immediately vest. In the event of voluntary termination by the executive prior to attaining retirement age or termination for cause, the executive’s outstanding RSUs and performance-based RSUs will be forfeited. Phantom Stock Units The 2007 Program authorizes the grant of phantom stock units to the extent provided for in the Company's employment agreements with certain executives. Each phantom stock unit entitles the recipient to receive a share of common stock at the individual's termination of employment or any other future date specified in the applicable employment agreement. Phantom stock units participate in dividend distribution on the same basis as the Company's common stock and Class B common stock. Dividend equivalents are issued in the form of additional units of phantom stock. The phantom stock units are fully vested at all times.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 13 – Commitments and Contingencies Environmental Matters The Company is subject to various federal, state, local, and foreign laws and regulations governing environmental matters, including the use, discharge, and disposal of hazardous materials. The Company’s manufacturing facilities are believed to be in substantial compliance with current laws and regulations. Complying with current laws and regulations has not had a material adverse effect on the Company’s financial condition. The Company has engaged environmental consultants and attorneys to assist management in evaluating potential liabilities related to environmental matters. Management assesses the input from these consultants along with other information known to the Company in its effort to continually monitor these potential liabilities. Management assesses its environmental exposure on a site-by-site basis, including those sites where the Company has been named as a “potentially responsible party.” Such assessments include the Company’s share of remediation costs, information known to the Company concerning the size of the hazardous waste sites, their years of operation, and the number of past users and their financial viability. As of December 31, 2021, the Company has accrued environmental liabilities of $10,919, of which $4,990 is included in other accrued liabilities on the accompanying consolidated balance sheet, and $5,929 is included in other noncurrent liabilities on the accompanying consolidated balance sheet. While the ultimate outcome of these matters cannot be determined, management does not believe that the final disposition of these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. The Company’s present and past facilities have been in operation for many years. These facilities have used substances and have generated and disposed of wastes which are or might be considered hazardous. Therefore, it is possible that additional environmental issues may arise in the future, which the Company cannot now predict. Litigation The Company is a party to various claims and lawsuits arising in the normal course of business. The Company is of the opinion that these litigations or claims will not have a material negative effect on its consolidated financial position, results of operations, or cash flows. Semiconductor Foundry Agreements The Company’s Siliconix subsidiary maintains long-term foundry agreements with subcontractors to ensure access to external front-end capacity. Since 2004, Siliconix has maintained long-term foundry arrangements for semiconductor manufacturing with Tower Semiconductor, pursuant to which Siliconix transferred certain technology to Tower Semiconductor and committed to purchase a minimum amount of semiconductor wafers. The Company has minimum purchase commitments pursuant to its current long-term arrangements with Tower Semiconductor and other foundry partners of $58,223 and $31,880 for the years 2022 through 2023, respectively. The minimum purchase commitments with Tower Semiconductor are based on a 18-month rolling forecast and, accordingly, the 2023 minimum purchase commitments will likely increase. The Company has the option to purchase wafers in addition to the minimum commitment and, accordingly, actual purchases may be different than the amounts disclosed above. The Company exceeded its minimum purchase commitments in 2021. Product Quality Claims The Company is a party to various product quality claims in the normal course of business. See Note 1 for further information on the Company's warranty obligations. Executive Employment Agreements The Company has employment agreements with certain of its senior executives. These employment agreements provide incremental compensation in the event of termination. The Company does not provide any severance or other benefits specifically upon a change in control.

Current Vulnerability Due to Certain Concentrations [Abstract]
Current Vulnerability Due to Certain Concentrations	Note 14 – Current Vulnerability Due to Certain Concentrations Market Concentrations No customer represented greater than 10% of consolidated net revenue in 2021 or 2020. A material portion of the Company's revenues are derived from the worldwide industrial, automotive, telecommunications, and computing markets. These markets have historically experienced wide variations in demand for end products. If demand for these end products should decrease, the producers thereof could reduce their purchases of the Company's products, which could have an adverse effect on the Company's results of operations and financial position. Certain subsidiaries and product lines have customers which comprise greater than 10% of the subsidiary's or product line's net revenues. The loss of one of these customers could have a material effect on the results of operations of the subsidiary or product line and financial position of the subsidiary, which could result in an impairment charge which could be material to the Company's consolidated financial statements. Credit Risk Concentrations Financial instruments with potential credit risk consist principally of cash and cash equivalents, short-term investments, accounts receivable, and notes receivable. Concentrations of credit risk with respect to receivables are generally limited due to the Company’s large number of customers and their dispersion across many countries and industries. No customer comprised greater than 10% of the Company’s accounts receivable balance as of December 31, 2021. As of December 31, 2020, one customer comprised 17.2% of the Company’s accounts receivable balance. No other customer comprised greater than 10% of the Company’s accounts receivable balance as of December 31, 2020. The Company continually monitors the credit risks associated with its accounts receivable and adjusts the allowance for uncollectible accounts accordingly. The credit risk exposure associated with the accounts receivable is limited by the allowance and is not considered material to the financial statements. The Company maintains cash and cash equivalents and short-term investments with various major financial institutions. The Company is exposed to credit risk related to the potential inability to access liquidity in financial institutions where its cash and cash equivalents and short-term investments are concentrated. As of December 31, 2021, the following financial institutions held over 10% of the Company’s combined cash and cash equivalents and short-term investments balance: JPMorgan* 22.6 % MUFG Bank Ltd. 20.6 % Bank Leumi* 12.8 % HSBC* 10.6 % *Participant in Credit Facility Sources of Supplies The production and sale of the Company’s products is reliant on a complex global interconnected supply chain of vendors, manufacturing facilities, third-party foundries and subcontractors, shipping partners, distributors, and end market customers. Disruption in one part of the supply chain could cause disruption in all other parts of the supply chain. Global shipping impacts several parts of the supply chain and the disruption experienced in the current year has, at times, negatively impacted the Company’s ability to manufacture products and to deliver them to customers. Although most materials incorporated into the Company's products are available from a number of sources, certain materials, including plastics and metals, are produced in only a limited number of regions around the world or are available from only a limited number of suppliers. Suppliers periodically extend lead times, face capacity constraints, limit supplies, increase prices, experience quality issues, or encounter cybersecurity or other issues that can interrupt or increase the cost of our supply. The unavailability or reduced availability of these materials could require the Company to temporarily cease or reduce production or incur additional costs. Customer requirements and certain laws pertaining to the responsible sourcing of materials, including tantalum, tungsten, tin, gold, and cobalt, all of which are used in the Company’s products, are increasing and becoming more stringent. Responsible sourcing efforts may result in increased prices and decreased availability of these materials. Many of the metals used in the manufacture of the Company’s products, including gold, copper, and palladium, are traded on active markets and can be subject to significant price volatility. To ensure adequate supply and to provide cost certainty, the Company’s policy is to enter into short-term commitments to purchase defined portions of annual consumption of the raw materials utilized if market prices decline below budget. If after entering into these commitments, the market prices for these raw materials decline, losses are recognized on these adverse purchase commitments. The Company's production can be disrupted by the unavailability of resources, such as water, electricity, and gases. The unavailability or reduced availability of these resources could require the Company to reduce production or incur additional costs. The Company uses third-party foundries and subcontractors for certain of its manufacturing activities, primarily wafer fabrication and the assembly and testing of finished goods. Establishing third-party contract manufacturer relationships can be time consuming and costly, and the number of qualified providers is limited. The Company's agreements with these manufacturers typically require it to commit to purchase services based on forecasted product needs, which may be inaccurate, and, in some cases, require the recognition of losses on these adverse purchase commitments. The Company's agreements may limit its ability to increase production, particularly during periods of growing demand for our products. Geographic Concentration The Company has operations outside the United States, and approximately 76% of revenues earned during 2021 were derived from sales to customers outside the United States. Additionally, as of December 31, 2021, $895,363 of the Company’s cash and cash equivalents and short-term investments were held by subsidiaries outside of the United States. Some of the Company’s products are produced and cash and cash equivalents and short-term investments are held in countries which are subject to risks of political, economic, and military instability. This instability could result in wars, riots, nationalization of industry, currency fluctuations, and labor unrest. These conditions could have an adverse impact on the Company’s ability to operate in these regions and, depending on the extent and severity of these conditions, could materially and adversely affect the Company’s overall financial condition, operating results, and ability to access its liquidity when needed. As of December 31, 2021 the Company’s cash and cash equivalents and short-term investments were concentrated in the following countries: Singapore 24.0 % Israel 18.8 % Germany 15.4 % United States 12.3 % People's Republic of China 11.4 % The Republic of China (Taiwan) 9.1 % Other Asia 6.2 % Other Europe 1.8 % Other 1.0 % Certain of the Company's non-U.S. subsidiaries have cash and cash equivalents and short-term investments deposited in U.S. financial institutions. Vishay has been in operation in Israel for 51 years. The Company has never experienced any material interruption in its operations attributable to these factors, in spite of several Middle East crises, including wars.

Segment and Geographic Data [Abstract]
Segment and Geographic Data	Note 15 – Segment and Geographic Data Vishay is a global manufacturer and supplier of electronic components. Vishay operates, and its chief operating decision maker makes strategic and operating decisions with regards to assessing performance and allocating resources based on, six reporting segments: MOSFETs, Diodes, Optoelectronic Components, Resistors, Inductors, and Capacitors. These segments represent groupings of product lines based on their functionality: ● Metal oxide semiconductor field effect transistors ("MOSFETs") function as solid state switches to control power. ● Diodes route, regulate, and block radio frequency, analog, and power signals; protect systems from surges or electrostatic discharge damage; or provide electromagnetic interference filtering. ● Optoelectronic components emit light, detect light, or do both. ● Resistors are basic components used in all forms of electronic circuitry to adjust and regulate levels of voltage and current. ● Inductors use an internal magnetic field to change alternating current phase and resist alternating current. ● Capacitors store energy and discharge it when needed. Vishay's reporting segments generate substantially all of their revenue from product sales to the industrial, automotive, telecommunications, computing, consumer products, power supplies, military and aerospace, and medical end markets. An immaterial portion of revenues are from royalties. The Company evaluates business segment performance on operating income, exclusive of certain items ("segment operating income"). Only dedicated, direct selling, general, and administrative expenses of the segments are included in the calculation of segment operating income. The Company's calculation of segment operating income excludes selling, general, and administrative costs of its global operations, sales and marketing, information systems, finance, and administration groups, as well as restructuring and severance costs, the direct impact of the COVID-19 pandemic, and other items affecting comparability. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company. These items represent reconciling items between segment operating income and consolidated operating income. Business segment assets are the owned or allocated assets used by each business. The Company also regularly evaluates gross profit by segment to assist in the analysis of consolidated gross profit. The Company considers segment operating income to be the more important metric because it more fully captures the business operations of the segments. The following tables set forth business segment information: MOSFETs Diodes Optoelectronic Components Resistors Inductors Capacitors Corporate / Other Total Year ended December 31, 2021: Net revenues $ 667,998 $ 709,416 $ 302,714 $ 752,554 $ 335,638 $ 472,167 $ - $ 3,240,487 Gross Profit 189,959 168,365 100,737 215,853 107,358 105,641 - $ 887,913 Segment Operating Income 148,652 145,814 82,378 190,953 97,482 85,342 - $ 750,621 Depreciation expense 30,257 40,406 14,585 34,344 14,448 17,129 8,078 $ 159,247 Capital expenditures 44,227 45,772 25,068 57,729 24,377 13,099 8,100 $ 218,372 Total Assets as of December 31, 2021: $ 503,937 $ 815,751 $ 377,815 $ 783,390 $ 355,353 $ 496,129 $ 210,882 $ 3,543,257 Year ended December 31, 2020: Net revenues $ 501,380 $ 502,548 $ 236,616 $ 606,183 $ 293,629 $ 361,542 $ - $ 2,501,898 Gross Profit 114,236 90,004 66,502 153,214 92,500 70,010 (4,563 ) $ 581,903 Segment Operating Income 76,548 69,663 50,369 130,700 82,472 50,753 (4,563 ) $ 455,942 Depreciation expense 30,835 39,380 16,003 32,531 13,821 17,349 8,198 $ 158,117 Capital expenditures 18,621 31,960 12,873 21,298 20,730 11,198 6,919 $ 123,599 Total Assets as of December 31, 2020: $ 447,867 $ 704,606 $ 341,517 $ 693,251 $ 330,092 $ 438,906 $ 198,234 $ 3,154,473 Year ended December 31, 2019: Net revenues $ 509,145 $ 557,143 $ 222,986 $ 657,192 $ 298,642 $ 423,197 $ - $ 2,668,305 Gross Profit 126,026 113,647 53,463 186,707 96,893 94,464 - $ 671,200 Segment Operating Income 88,994 94,130 37,145 162,969 86,395 74,063 - $ 543,696 Depreciation expense 32,614 38,930 16,803 28,909 13,316 17,253 8,160 $ 155,985 Capital expenditures 35,131 38,242 12,448 34,395 17,836 9,916 8,673 $ 156,641 Total Assets as of December 31, 2019: $ 404,412 $ 755,945 $ 328,871 $ 653,195 $ 334,791 $ 449,823 $ 193,738 $ 3,120,775 ________________ Years ended December 31, 2021 2020 2019 Reconciliation: Segment Operating Income $ 750,621 $ 455,942 $ 543,696 Restructuring and Severance Costs - (743 ) (24,139 ) Impact of COVID-19 Pandemic on Selling, General, and Administrative Expenses - 1,451 - Unallocated Selling, General, and Administrative Expenses (282,819 ) (246,940 ) (257,127 ) Consolidated Operating Income (Loss) $ 467,802 $ 209,710 $ 262,430 Unallocated Other Income (Expense) (33,192 ) (51,382 ) (36,132 ) Consolidated Income Before Taxes $ 434,610 $ 158,328 $ 226,298 The Company has a broad line of products that it sells to OEMs, EMS companies, and independent distributors.

Earnings Per Share [Abstract]
Earnings Per Share	Note 16 – Earnings Per Share Basic earnings per share is computed using the weighted average number of common shares outstanding during the periods presented. Diluted earnings per share is computed using the weighted average number of common shares outstanding adjusted to include the potentially dilutive effect of restricted stock units (see Note 12), convertible debt instruments (see Note 6), and other potentially dilutive securities. The following table sets forth the computation of basic and diluted earnings per share attributable to Vishay stockholders (shares in thousands) Years ended December 31, 2021 2020 2019 Numerator: Net earnings attributable to Vishay stockholders $ 297,970 $ 122,923 $ 163,936 Denominator: Denominator for basic earnings per share: Weighted average shares 144,796 144,641 144,427 Outstanding phantom stock units 209 195 181 Adjusted weighted average shares - basic 145,005 144,836 144,608 Effect of dilutive securities: Restricted stock units 488 362 428 Convertible debt instruments 2 30 100 Dilutive potential common shares 490 392 528 Denominator for diluted earnings per share: Adjusted weighted average shares - diluted 145,495 145,228 145,136 Basic earnings per share attributable to Vishay stockholders $ 2.05 $ 0.85 $ 1.13 Diluted earnings per share attributable to Vishay stockholders $ 2.05 $ 0.85 $ 1.13 Diluted earnings per share for the years presented do not reflect the following weighted average potential common shares, as the effect would be antidilutive (in thousands) Years ended December 31, 2021 2020 2019 Convertible debt instruments: Convertible Senior Debentures, due 2041 - 100 301 Convertible Senior Notes, due 2025 - 17,062 19,063 Weighted average other 279 341 315 If the average market price of Vishay common stock is less than the effective conversion price of the convertible senior notes due 2025, no shares are included in the diluted earnings per share computation for the convertible senior notes due 2025. Upon Vishay exercising its existing right to legally amend the indenture governing the convertible senior notes due 2025, Vishay will satisfy its conversion obligations by paying $1 cash per $1 principal amount of converted notes and settle any additional amounts due in common stock. Accordingly, the notes are not anti-dilutive when the average market price of Vishay common stock is less than the effective conversion price of the convertible senior notes due 2025.

Fair Value Measurements	Note 18 – Fair Value Measurements The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis: Total Fair Value Level 1 Level 2 Level 3 December 31, 2021 Assets: Assets held in rabbi trusts $ 59,687 $ 32,713 $ 26,974 $ - Available for sale securities $ 4,455 4,455 - - Non - U.S. Defined Benefit Pension Plan Assets: Equity securities $ 10,627 10,627 - - Fixed income securities $ 19,690 19,690 - - Cash $ 45,603 45,603 - - $ 140,062 $ 113,088 $ 26,974 $ - December 31, 2020 Assets: Assets held in rabbi trusts $ 57,892 $ 34,145 $ 23,747 $ - Available for sale securities $ 4,917 4,917 - - Non - U.S. Defined Benefit Pension Plan Assets: Equity securities $ 9,446 9,446 - - Fixed income securities $ 18,105 18,105 - - Cash $ 46,783 46,783 - - $ 137,143 $ 113,396 $ 23,747 $ - As described in Note 6, the Company allocated the aggregate repurchase payment of convertible debt instruments between the associated liability and equity components of the repurchased convertible debt instruments based on a nonrecurring fair value measurement of the convertible senior debentures immediately prior to the repurchases in 2020 and 2019. The nonrecurring fair value measurements are considered Level 3 measurements. See Note 6 for further information on the measurements and inputs. The Company maintains non-qualified trusts, referred to as “rabbi” trusts, to fund payments under deferred compensation and non-qualified pension plans. Rabbi trust assets consist primarily of marketable securities, classified as available-for-sale, and company-owned life insurance assets. The marketable securities held in the rabbi trusts are valued using quoted market prices on the last business day of the year. The company-owned life insurance assets are valued in consultation with the Company’s insurance brokers using the value of underlying assets of the insurance contracts. The fair value measurement of the marketable securities held in the rabbi trust is considered a Level 1 measurement and the measurement of the company-owned life insurance assets is considered a Level 2 measurement within the fair value hierarchy. The Company maintains defined benefit retirement plans in certain of its non-U.S. subsidiaries. The assets of the plans are measured at fair value. Equity securities held by the non-U.S. defined benefit retirement plans consist of equity securities that are valued based on quoted market prices on the last business day of the year. The fair value measurement of the equity securities is considered a Level 1 measurement within the fair value hierarchy. Fixed income securities held by the non-U.S. defined benefit retirement plans consist of government bonds in the Philippines and India and corporate notes that are valued based on quoted market prices on the last business day of the year. The fair value measurement of the fixed income securities is considered a Level 1 measurement within the fair value hierarchy. Cash held by the non-U.S. defined benefit retirement plans consists of demand deposits on account in various financial institutions to fund current benefit payments. The carrying amount of the cash approximates its fair value. The Company holds investments in debt securities that are intended to fund a portion of its pension and other postretirement benefit obligations outside of the U.S. The investments are valued based on quoted market prices on the last business day of the year. The fair value measurement of the investments is considered a Level 1 measurement within the fair value hierarchy. The Company enters into forward contracts with highly-rated financial institutions to mitigate the foreign currency risk associated with intercompany loans denominated in a currency other than the legal entity's functional currency. The notional amount of the forward contracts was $100,000 as of December 31, 2021 and 2020. The forward contracts are short-term in nature and are expected to be renewed at the Company's discretion until the intercompany loans are repaid. We have not designated the forward contracts as hedges for accounting purposes, and as such the change in the fair value of the contracts is recognized in the consolidated statement of operations as a component of other income (expense). The Company estimates the fair value of the forward contracts based on applicable and commonly used pricing models using current market information and is considered a Level 2 measurement within the fair value hierarchy. The value of the forward contracts was immaterial as of December 31, 2021 and 2020. The Company does not utilize derivatives or other financial instruments for trading or other speculative purposes. The fair value of the long-term debt, excluding the deferred financing costs, at December 31, 2021 and 2020 is approximately $485,500 and $491,400, respectively, compared to its carrying value, excluding the derivative liability and capitalized deferred financing costs, of $465,344 and $406,398, respectively. The Company estimates the fair value of its long-term debt using a combination of quoted market prices for similar financing arrangements and expected future payments discounted at risk-adjusted rates, which are considered level 2 inputs. At December 31, 2021 and 2020, the Company’s short-term investments were comprised of time deposits with financial institutions that have maturities that exceed 90 days from the date of acquisition; however they all mature within one year from the respective balance sheet dates. The Company's short-term investments are accounted for as held-to-maturity debt instruments, at amortized cost, which approximates their fair value. The investments are funded with excess cash not expected to be needed for operations prior to maturity; therefore, the Company believes it has the intent and ability to hold the short-term investments until maturity. At each reporting date, the Company performs an evaluation to determine if any unrealized losses are other-than-temporary. No other-than-temporary impairments have been recognized on these securities, and there are no unrecognized holding gains or losses for these securities during the periods presented. There have been no transfers to or from the held-to-maturity classification. All decreases in the account balance are due to returns of principal at the securities’ maturity dates. Interest on the securities is recognized as interest income when earned. At December 31, 2021 and 2020, the Company’s cash and cash equivalents were comprised of demand deposits, time deposits with maturities of three months or less when purchased, and money market funds. The Company estimates the fair value of its cash, cash equivalents, and short-term investments using level 2 inputs. Based on the current interest rates for similar investments with comparable credit risk and time to maturity, the fair value of the Company's cash, cash equivalents, and held-to-maturity short-term investments approximate the carrying amounts reported in the accompanying consolidated balance sheets. The Company’s financial instruments also include accounts receivable and accounts payable. The carrying amounts for these financial instruments reported in the accompanying consolidated balance sheets approximate their fair values.

Related Party Transactions	Note 19 – Related Party Transactions Vishay Precision Group, Inc. On July 6, 2010, Vishay completed the spin-off of its measurements and foil resistors businesses into an independent, publicly-traded company, Vishay Precision Group, Inc. Vishay’s common stockholders received 1 share of VPG common stock for every 14 shares of Vishay common stock they held on the record date, June 25, 2010, and Vishay’s Class B common stockholders received 1 share of VPG Class B common stock for every 14 shares of Vishay Class B common stock they held on the record date. Following the spin-off, VPG is an independent company and Vishay retains no ownership interest. Relationship with VPG after Spin-off Following the spin-off, VPG and Vishay operate separately, each as independent public companies. Vishay has no ownership interest in VPG. However, Ruta Zandman solely or on a shared basis with Marc Zandman and Ziv Shoshani, all of whom are members of Vishay's Board of Directors, control a large portion of the voting power of both Vishay and VPG. Marc Zandman, Vishay’s Executive Chairman of the Board and an executive officer of Vishay, serves as the Chairman of VPG. Ziv Shoshani, CEO of VPG, serves as a director of Vishay. Additionally, Timothy V. Talbert, a member of Vishay’s Board of Directors is also a member of the Board of Directors of VPG. In connection with the completion of the spin-off, Vishay and its subsidiaries entered into several agreements with VPG and its subsidiaries that govern the relationship of the parties following the spin-off. Among the agreements entered into with VPG and its subsidiaries were a transition services agreement, several lease agreements, and supply agreements. None of the agreements have had nor are expected to have a material impact on Vishay’s financial position, results of operations, or liquidity. Some of these agreements have expired and have not been renewed. Vishay also entered into a trademark license agreement with VPG pursuant to which Vishay granted VPG the license to use certain trademarks, service marks, logos, trade names, entity names, and domain names which include the term “Vishay.” The license granted VPG the limited, exclusive, royalty-free right and license to use certain marks and names incorporating the term “Vishay” in connection with the design, development, manufacture, marketing, provision and performance of certain VPG products that do not compete with any products within Vishay’s product range as constituted immediately following the separation and certain services provided in connection with the products. The license cannot be terminated except as a result of willful misconduct or liquidation bankruptcy of VPG.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Summary of Significant Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Vishay and all of its subsidiaries in which a controlling financial interest is maintained. For those consolidated subsidiaries in which the Company’s ownership is less than 100 percent, the outside stockholders’ interests are shown as noncontrolling interest in the accompanying consolidated balance sheets. Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis. Investments in affiliates over which the Company does not have significant influence are accounted for by the cost method. All intercompany transactions, accounts, and profits are eliminated.
Revenue Recognition	Revenue Recognition The Company recognizes revenue from contracts with customers when it satisfies the performance obligations within the contract. The Company has framework agreements with many of its customers that contain the terms and conditions of future sales, but do not create enforceable rights or obligations. For revenue recognition purposes, the Company considers the combined purchase orders and the terms and conditions contained within such framework agreements to be contracts. Payment terms for the Company's sales are generally less than sixty days. Substantially all of the Company's receivables historically have been and are expected to continue to be collected within twelve months of the transfer of products to the customer and the Company expects this to continue going forward. Accordingly, the Company does not recognize a financing component of the transaction price. Revenue is measured based on the consideration specified in contracts with customers, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies its performance obligations. The Company analyzes its contracts to determine whether the promise in the contract to construct and transfer goods to the customer is a performance obligation that will be satisfied over time or at a point in time. When the Company's performance does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date, the Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time. The Company has a limited number of contracts for custom products that meet the criteria to recognize revenue over time. The Company's contracts contain two performance obligations: delivery of products and warranty protection. The Company does not sell separate, enhanced, or extended warranty coverage, but through its customary business practices, the Company has created implied service-type warranties, which are accounted for as separate performance obligations. Revenue is allocated between these two performance obligations and recognized as the obligations are satisfied. The allocation of revenue to warranty protection is based on an estimate of expected cost plus margin. The delivery of products performance obligation is satisfied and product sales revenue is recognized when the customer takes control of the products. Warranty revenue is deferred and the warranty protection performance obligation is satisfied and revenue is recognized over the warranty period, which is typically less than twenty four months from sale to end customer. The warranty deferred revenue liability is recorded within Other Accrued Expenses and Other Liabilities on the accompanying consolidated balance sheets. The deferred revenue balance associated with the service-type warranty performance obligations and the components that comprise the change in the deferred revenue balance are not significant. The Company has a broad line of products that it sells to original equipment manufacturers ("OEMs"), electronic manufacturing services ("EMS") companies, which manufacture for OEMs on an outsourcing basis, and independent distributors that maintain large inventories of electronic components for resale to OEMs and EMS companies. Note 1 – Summary of Significant Accounting Policies (continued) The Company recognizes revenue on sales to distributors when the distributor takes control of the products ("sold-to" model). The Company has agreements with distributors that allow distributors a limited credit for unsaleable products, which it terms a "scrap allowance." Consistent with industry practice, the Company also has a "stock, ship and debit" program whereby it considers requests by distributors for credits on previously purchased products that remain in distributors' inventory, to enable the distributors to offer more competitive pricing. In addition, the Company has contractual arrangements whereby it provides distributors with protection against price reductions initiated by the Company after product is sold by the Company to the distributor and prior to resale by the distributor. The Company recognizes the estimated variable consideration to be received as revenue and records a related accrued expense for the consideration not expected to be received, based upon its estimate of product returns, scrap allowances, "stock, ship and debit" credits, and price protection credits that will be attributable to sales recorded through the end of the period. The Company makes these estimates based upon sales levels to its distributors during the period, inventory levels at the distributors, current and projected market conditions, and historical experience under the programs. While the Company utilizes a number of different methodologies to estimate the accruals, all of the methodologies take into account sales levels to distributors during the relevant period, inventory levels at the distributors, current and projected market trends and conditions, recent and historical activity under the relevant programs, changes in program policies, and open requests for credits. These procedures require the exercise of significant judgments. The Company believes that it has a reasonable basis to estimate future credits under the programs. See sales returns and allowances accrual activity in Note 9. The Company pays commissions to external sales representatives on a per-sale basis. Accordingly, these commissions are expensed as incurred because the future amortization period of the asset that the Company otherwise would have recognized is one year or less. Internal staff are not paid commissions. The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the product even if the shipping and handling activities are performed after the customer obtains control. The Company does not evaluate whether shipping and handling activities are promised services to its customers. If control transfers and revenue is recognized for the related products before the shipping and handling activities occur, the related costs of those shipping and handling activities is accrued. The Company applies this accounting policy election consistently to similar types of transactions. See disaggregated revenue information in Note 15
Research and Development Expenses	Research and Development Expenses Research and development costs are expensed as incurred. The amount charged to expense for research and development (exclusive of purchased in-process research and development) aggregated $77,377, $70,861, and $69,827, for the years ended December 31, 2021, 2020, and 2019, respectively. The Company spends additional amounts for the development of machinery and equipment for new processes and for cost reduction measures.
Income Taxes	Income Taxes The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances have been established for deferred tax assets which the Company believes do not meet GAAP criteria of “more likely than not” to be realized. This criterion requires a level of judgment regarding future taxable income, which may be revised due to changes in market conditions, tax laws, or other factors. If the Company’s assumptions and estimates change in the future, valuation allowances established may be increased, resulting in increased tax expense. Conversely, if the Company is ultimately able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been established, then the related portion of the valuation allowance can be released, resulting in decreased tax expense. The Company and its subsidiaries are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite the Company’s belief that its tax return positions are fully supportable. The Company adjusts these reserves in light of changing facts and circumstances and the provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. These accruals for tax-related uncertainties are based on management’s best estimate of potential tax exposures. When particular matters arise, a number of years may elapse before such matters are audited by tax authorities and finally resolved. Favorable resolution of such matters could be recognized as a reduction to the Company’s effective tax rate in the year of resolution. Unfavorable resolution of any particular issue could increase the effective tax rate and may require the use of cash in the year of resolution. The amount included in current liabilities on the accompanying consolidated balance sheets reflect only amounts expected to be settled in cash within one year. See Note 5.
Cash, Cash Equivalents, and Short-Term Investments	Cash, Cash Equivalents, and Short-Term Investments Cash and cash equivalents includes demand deposits and highly liquid investments with maturities of three months or less when purchased. Highly liquid investments with original maturities greater than three months, but less than one year are classified as short-term investments. At December 31, 2021 and 2020, the Company’s short-term investments were comprised of time deposits with financial institutions whose original maturity exceeds three months, but less than one year.
Allowance for Credit Losses	Allowance for Credit Losses Effective January 1, 2020, the Company estimates its credit losses on financial instruments using a current expected credit loss model. Prior to January 1, 2020, the Company estimated its credit losses using an incurred loss impairment methodology, which was not materially different than the methodology adopted on January 1, 2020. The Company maintains an allowance for accounts receivable credit losses resulting from the inability of its customers to make required payments. $ , $ , and $ for the years ended , , and , respectively. The Company’s cash equivalents, short-term investments, and restricted investments are accounted for as held-to-maturity debt instruments, at amortized cost. Interest income on these instruments is recorded as Other income on the consolidated statements of operations and interest receivable is recognized as a separate asset and recorded in Prepaid expenses and other current assets on the consolidated balance sheets. The Company has not experienced a credit loss on the principal or interest receivable of its cash equivalents, short-term investments, or restricted investments. The Company pools its cash equivalents, short-term investments, and restricted investments by credit rating of the issuing financial institution and estimates an allowance for credit losses based on the corporate bond default ratios, evaluation of the impact of current and projected economic conditions, and probability of credit loss. Net credit loss expense for cash equivalents, short-term investments, and restricted investments was immaterial for the years ended December 31, 2021 and 2020. The Company does not measure an allowance for credit losses on interest receivable. Any uncollectible interest receivable is recognized by reversing interest income within the fiscal quarter that the interest becomes uncollectible. The Company has an immaterial amount of other short-term held-to-maturity debt instruments recorded within Prepaid expenses and other current assets on the consolidated balance sheets. The Company analyzes these assets on a separate asset basis and estimates an allowance for credit losses based on historical credit loss rates and an evaluation of the impact of current and projected economic conditions. Net credit loss expense for these other short-term held-to-maturity debt instruments was immaterial for the years ended December 31, 2021 and 2020.
Inventories	Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out method, or net realizable value. Inventories are adjusted for estimated obsolescence and written down to net realizable value based upon estimates of future demand, technology developments, and market conditions.
Property and Equipment	Property and Equipment Property and equipment is carried at cost and is depreciated principally by the straight-line method based upon the estimated useful lives of the assets. Machinery and equipment are being depreciated over useful lives of to . Buildings and building improvements are being depreciated over useful lives of to . Construction in progress is not depreciated until the assets are placed in service. The estimated cost to complete construction in progress at was approximately $ . Excluded from the estimated cost to complete construction in progress are costs for projects that have recently begun for which there are no contractual commitments to complete the project, including Depreciation expense was $ , $ , and $ for the years ended , , and , respectively. Gains and losses on the disposal of assets which do not qualify for presentation as discontinued operations are included in the determination of operating margin (within selling, general, and administrative expenses). Individually material gains and losses on disposal are separately disclosed in the notes to the consolidated financial statements.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of a business acquired over the fair value of the related net assets at the date of acquisition. Certain intangible assets may be assigned indefinite useful lives. Goodwill and indefinite-lived intangible assets are not amortized but rather are tested for impairment at least annually. These tests are performed more frequently whenever events or changes in circumstances indicate that the assets might be impaired. The Company's business segments (see Note 15) represent its reporting units for goodwill impairment testing purposes. At December 31, 2021 and 2020, respectively, the Company has no recorded indefinite-lived intangible assets. Definite-lived intangible assets are amortized over their estimated useful lives. Patents and acquired technology are being amortized over useful lives of seven years to twenty-five years. Capitalized software is amortized over periods of three years to ten years, primarily included in costs of products sold on the consolidated statements of operations. Customer relationships are amortized over useful lives of five years to twenty years. Noncompete agreements are amortized over periods of three years to ten years. The Company continually evaluates the reasonableness of the useful lives of these assets. GAAP prescribes a quantitative method for determining goodwill impairment. The Company has the option of performing a qualitative assessment before performing the quantitative impairment test. If it is determined, on the basis of qualitative factors, that the fair value of the reporting unit is not more likely than not less than the carrying amount, the quantitative impairment test is not required. If it is determined that the fair value of the reporting unit is more likely than not less than the carrying amount, the quantitative impairment test is required. The Company determines the fair value of the reporting unit and compares that fair value to the net book value of the reporting unit. The fair value of the reporting unit is determined using various valuation techniques, including a comparable companies market multiple approach and a discounted cash flow analysis (an income approach). If the net book value of the reporting unit were to exceed the fair value, the Company would recognize an impairment charge.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The carrying value of long-lived assets held-and-used, other than goodwill and indefinite-lived intangible assets, is evaluated when events or changes in circumstances indicate the carrying value may not be recoverable or the useful life has changed. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from such asset group are separately identifiable and are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset group. Fair market value is determined primarily using present value techniques based on projected cash flows from the asset group. Losses on long-lived assets held-for-sale, other than goodwill and indefinite-lived intangible assets, are determined in a similar manner, except that fair market values are reduced for anticipated disposal costs.
Available-for-Sale Securities	Available-for-Sale Securities Short-term investments and other assets reported on the accompanying consolidated balance sheets include time deposits with financial institutions whose original maturity exceeds three months, but less than one year that are classified as held-to-maturity instruments, and investments in marketable securities that are classified as available-for-sale instruments. The available-for-sale instruments include assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans (see Note 11) and assets that are intended to fund a portion of the Company’s other postretirement benefit obligations outside of the U.S. These assets are reported at fair value, based on quoted market prices as of the end of the reporting period. Unrealized gains and losses are reported as Other Income (Expense) on the consolidated statements of operations. At the time of sale, the assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans, any gains (losses) calculated by the specific identification method are recognized as a reduction (increase) to benefits expense, within selling, general, and administrative expenses.
Financial Instruments	Financial Instruments The Company uses financial instruments in the normal course of its business, including from time to time, derivative financial instruments. Additionally, from time to time, the Company enters into contracts that are not considered derivative financial instruments in their entirety, but that include embedded derivative features. Other financial instruments include cash and cash equivalents, held-to-maturity short-term investments, accounts receivable, and notes payable. The carrying amounts of these financial instruments reported on the accompanying consolidated balance sheets approximate their fair values due to the short-term nature of these assets and liabilities. Note 1 – Summary of Significant Accounting Policies (continued) The fair value measurement accounting guidance establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the Company’s own assumptions. An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
Stock-Based Compensation	Stock-Based Compensation Compensation costs related to stock-based payment transactions are recognized in the consolidated financial statements. The amount of compensation cost is measured based on the grant-date fair value of the equity (or liability) instruments issued. The Company determines compensation cost for restricted stock units ("RSUs") and phantom stock units based on the grant-date fair value of the underlying common stock adjusted for expected dividends paid over the required vesting period for non-participating awards. Compensation cost is recognized over the period that an officer, employee, or non-employee director is required to provide service in exchange for the award. For awards subject to graded vesting, the Company recognizes expense over the service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards. The Company recognizes compensation cost for RSUs that are expected to vest and records cumulative adjustments in the period that the expectation changes.
Foreign Currency Translation	Foreign Currency Translation The Company has significant operations outside of the United States. The Company finances its operations in Europe and certain locations in Asia in local currencies, and accordingly, these subsidiaries utilize the local currency as their functional currency. The Company’s operations in Israel and most significant locations in Asia are largely financed in U.S. dollars, and accordingly, these subsidiaries utilize the U.S. dollar as their functional currency. For those subsidiaries where the local currency is the functional currency, assets and liabilities on the accompanying consolidated balance sheets have been translated at the rate of exchange as of the balance sheet date. Translation adjustments do not impact the consolidated results of operations and are reported as a separate component of stockholders’ equity. Revenues and expenses are translated at the average exchange rate for the year. While the translation of revenues and expenses into U.S. dollars does not directly impact the statement of operations, the translation effectively increases or decreases the U.S. dollar equivalent of revenues generated and expenses incurred in those foreign currencies. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency financial statement amounts are remeasured into U.S. dollars. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in the consolidated results of operations.
Commitments and Contingencies	Commitments and Contingencies The Company has commitments for the purchase of assets to complete its construction in progress as disclosed above. The commitment period for substantially all of these purchase commitments is less than one year. The Company expects to have noncancellable purchase commitments with commitment periods in excess of one year associated with its significant facility expansion programs as the programs progress. As of December 31, 2021, there are no material noncancellable commitments associated with these programs. Note 1 – Summary of Significant Accounting Policies (continued) Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. The costs for a specific environmental remediation site are discounted if the aggregate amount of the obligation and the amount and timing of the cash payments for that site are fixed or reliably determinable based upon information derived from the remediation plan for that site. Accrued liabilities for environmental matters recorded at December 31, 2021 and 2020 do not include claims against third parties.
Restructuring and Severance Costs	Restructuring and Severance Costs Restructuring and severance costs reflect charges resulting from cost reduction programs implemented by the Company. Restructuring and severance costs include exit costs, severance benefits pursuant to an on-going arrangement, voluntary termination compensation under a defined program, and any related pension curtailment and settlement charges. The Company recognizes expense for one-time benefits only after management has committed to a plan, the plan is sufficiently detailed to provide the number, classification, and location of employees to be terminated as well as the expected completion date, the plan has been sufficiently communicated to employees such that they are able to determine the type and amount of benefits they will receive if terminated, and it is unlikely that the plan will be significantly changed or withdrawn. If an employee is not required to render service beyond a minimum retention period, the Company recognizes expense once the aforementioned criteria have been met. If an employee is required to render service beyond a minimum retention period, the Company recognizes expense over the period that the employee is required to render future service. The Company recognizes expense for on-going benefit arrangements when the liability is reasonably estimable and considered probable. The Company recognizes expense for voluntary separation / early retirement when the employee delivers an irrevocable voluntary termination notice pursuant to a defined Company program. The Company recognizes other exit costs as incurred.
Self-Insurance Programs	Self-Insurance Programs The Company uses a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for workers’ compensation, general liability, property damage, director and officers’ liability, and vehicle liability. As part of its self-insurance program for certain risks, the Company created a wholly-owned captive insurance entity in 2007. At December 31, 2021, the captive insurance entity provides only property and general liability insurance, although it is licensed to also provide directors’ and officers’ insurance. The captive insurance entity had no amounts accrued for outstanding claims at December 31, 2021 and 2020. Certain investments held by the captive insurance entity are restricted primarily for the purpose of potential insurance claims. Such amounts are recorded in other noncurrent assets, and total $9,153 and $9,281 at December 31, 2021 and 2020, respectively, representing required statutory reserves of the captive insurance entity.
Leases	Leases The Company leases buildings and machinery and equipment used for manufacturing and/or sales and administrative purposes. The Company is also party to various service, warehousing, and other agreements that it evaluates for potential embedded leases. Substantially all of the Company’s leases are structured and classified as operating leases. The Company leases assets in each region in which it operates. The Company’s leases are generally denominated in the currency of the leased assets' location, which may not be the functional currency of the subsidiary lessee. Accordingly, the Company remeasures its lease liability and recognizes a transactional gain/loss for leases denominated in currencies other than the functional currency of the subsidiary lessee. The Company recognizes right of use assets and lease liabilities for leases greater than twelve months in duration based on the contract consideration for lease components through the term of the lease and the applicable discount rate. Leases with a duration less than or equal to twelve months are considered short-term leases. The Company does not recognize right of use assets or lease liabilities for short-term leases and classifies the expense as short-term lease expense. Variable lease payments based on an index or rate are included in the right of use assets and lease liabilities based on the effective rates at lease commencement. Changes in the rates or indices do not impact the right of use asset or lease liability and are recognized as a component of lease expense in the consolidated statements of operations. Variable lease payments not based on an index or rate are not included in the initial right of use asset and lease liability and are recognized when incurred as a component of lease expense in the consolidated statements of operations. The Company has elected to not separate contract consideration for lease and non-lease components for its building leases. In addition to the noncancellable period of a lease, the Company includes periods covered by extension options it is reasonably certain to exercise, termination options that it is reasonably certain not to exercise, and extension and termination options controlled by the lessor in its determination of the lease term. The Company uses the rate implicit in the contract whenever possible when determining the applicable discount rate. When the implicit rate is not used, the Company employs a portfolio approach based on the duration of the lease. The portfolio lease rates are calculated monthly. No individual lease is considered significant and there are no leases that have not yet commenced that are considered significant. See Note 3.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Guidance Adopted In August 2020, the Financial Accounting Standards Board ("FASB") Debt – Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity

Earnings Per Share [Abstract]
Discussion on convertible debt included in computation of earnings per share diluted	If the average market price of Vishay common stock is less than the effective conversion price of the convertible senior notes due 2025, no shares are included in the diluted earnings per share computation for the convertible senior notes due 2025. Upon Vishay exercising its existing right to legally amend the indenture governing the convertible senior notes due 2025, Vishay will satisfy its conversion obligations by paying $1 cash per $1 principal amount of converted notes and settle any additional amounts due in common stock. Accordingly, the notes are not anti-dilutive when the average market price of Vishay common stock is less than the effective conversion price of the convertible senior notes due 2025.
