Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. The consolidated financial statements of AVX Corporation and its subsidiaries (“AVX” or the “Company”) include all accounts of the Company and its subsidiaries. All significant intercompany transactions and accounts have been eliminated. We have prepared the accompanying financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. These consolidated financial statements are unaudited and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments and accruals, necessary for the fair statement of the consolidated balance sheets, operating results, comprehensive income, statements of stockholders’ equity and cash flows for the periods presented. Operating results for the three June 30, 2019 not may March 31, 2020 10 March 31, 2019. Summary of Significant Accounting Policies We have identified the accounting policies and estimates that are critical to our business operations and understanding our results of operations. Those policies and estimates can be found in Note 1, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements and in “Critical Accounting Policies and Estimates,” in “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10 -K for the fiscal year ended March 31, 2019. Accordingly, this Quarterly Report on Form 10 -Q should be read in conjunction with our Annual Report on Form 10 -K for the fiscal year ended March 31, 2019. During the three month period ended June 30, 2019, there were no significant changes to any critical accounting policies or to the methodology used in determining estimates including those related to investment securities, inventories, goodwill, intangible assets, property and equipment, and contingencies other than those discussed below. During the three month period ended June 30, 2019, goodwill increased by due to foreign currency translation. Reclassifications Certain amounts in the prior year consolidated financial statements have been reclassified to the current year presentation. The impact of the reclassifications made to prior year amounts is not material and did not affect net loss. Relevant New Accounting Standards In 2016, the FASB issued ASU 2016 - 02, “Leases”. This guidance changes the requirements for inclusion of certain right-of-use assets and the associated liabilities to be included in a statement of financial position. The Company adopted this guidance effective April 1, 2019, using the modified retrospective method and utilized the optional transition method under which the Company will continue to apply the legacy guidance in Accounting Standards Codification (“ASC”) 840, including its disclosure requirements, in the comparative period presented. In addition, the Company elected the package of practical expedients permitted under the transition guidance which permits the following: a) carrying forward the historical lease classification, b) not separating lease components from non-lease components within the Company’s facility lease contracts, c) not presenting comparative periods but rather recording a cumulative catch-up during fiscal 2020, and d) electing, by asset class, not to record on the balance sheet a lease whose term is twelve months or less including reasonably certain renewal options. As a result of the adoption of ASU 2016 - 02 for the fiscal year beginning April 1, 2019, the Company recorded initial operating lease right-of-use assets and operating lease liabilities related of and respectively. Right-of-use assets are included in “Other assets” on the Company’s Balance Sheet as of June 30, 2019. Lease liabilities are classified as current and non-current, and are included in “Accrued expenses” and “Other liabilities”, respectively, on the Company’s Balance Sheet as of June 30, 2019. Please refer to Note 2 for additional information. In June 2016, the FASB issued ASU 2016 - 13, “Financial Instruments – Credit Losses: Measurements of Credit Losses on Financial Instruments.” This standard requires the measurement and recognition of expected credit losses held at amortized cost. This new standard replaces the use of forward-looking information to estimate credit losses and requires credit losses for available for sale debt securities to be recorded through an allowance for credit losses rather than a reduction in the amortized cost basis. This update is effective for public companies for annual reporting periods beginning after December 15, 2019. Management is currently evaluating the impact of ASU 2016 - 13 on our consolidated financial statements. In August 2017, the FASB issued ASU 2017 - 12, “Derivatives and Hedging.” The standard aims to align the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results for cash flow and fair value hedge accounting with risk management activities. The guidance is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. Additionally, in October 2018, the FASB issued ASU 2018 - 16, “Derivatives and Hedging (Topic 815 ): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes”, which permits use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. This update is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. For entities that have not yet adopted ASU 2017 - 12, the concurrent adoption of ASU 2018 - 16 is required. The Company concurrently adopted ASU 2017 - 12 and ASU 2018 - 16 effective April 1, 2019. The adoption of these standards has not had a material impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018 - 02, "Income Statement - Reporting Comprehensive Income." This standard allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for any interim and annual financial statements that have not yet been issued. The Company adopted ASU 2018 - 02 effective April 1, 2019 and elected to not reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. The adoption of this standard has not had a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018 - 13, “Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement”. This standard removes, adds and modifies certain disclosure requirements in the existing framework. ASU 2018 - 13 removes the following disclosure requirements: (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the entity’s valuation processes for Level 3 fair value measurements. ASU 2018 - 13 adds the following disclosure requirements: (i) provide information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date rather than a point in the future, (ii) disclose changes in unrealized gains and losses related to Level 3 measurements for the period included in other comprehensive income, and (iii) disclose for Level 3 measurements the range and weighted average of the significant unobservable inputs and the way it is calculated. ASU 2018 - 13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. We are currently evaluating the potential impact on our consolidated financial statements and disclosures. In August 2018, the FASB issued ASU 2018 - 14, “Compensation – Retirement Benefits – Defined Benefit Plans – General.” This standard removes certain disclosures that are not considered cost beneficial, clarifies certain required disclosures and added additional disclosures. The standard is effective for fiscal years beginning after December 15, 2020, and early adoption is permitted. The amendments in ASU 2018 - 14 would need to be applied on a retrospective basis. We are currently assessing the impact the new guidance will have on our disclosures. In August 2018, the FASB issued ASU 2018 - 15, “Customer’s Accounting For Implementation Costs Incurred In A Cloud Computing Arrangement That Is A Service Contract”. This guidance reduces the complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This update is effective for public companies for annual reporting periods beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company early adopted this standard effective April 1, 2019, utilizing the prospective approach to all implementation costs incurred after the date of adoption. The adoption of ASU 2018 - 15 has not had a material impact on our consolidated financial statements. We have reviewed other newly issued accounting pronouncements and concluded that they are either not applicable to our business or that no material effect is expected on our consolidated financial statements as a result of future adoption.

Earnings Per Share [Text Block]	3. Basic earnings per share are computed by dividing net earnings by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share are computed by dividing net earnings by the sum of (a) the weighted average number of shares of common stock outstanding during the period and (b) the dilutive effect of potential common stock equivalents during the period. Stock options and unvested service-based RSU awards make up the common stock equivalents and are computed using the treasury stock method.

Derivative Instruments and Hedging Activities Disclosure [Text Block]	12. We are exposed to foreign currency exchange rate fluctuations in the normal course of business. We use derivative instruments (forward contracts) to hedge certain foreign currency exposures as part of our risk management strategy. The objective is to offset gains and losses resulting from these exposures with gains and losses on the forward contracts used to hedge them, thereby reducing volatility of earnings or protecting fair values of assets and liabilities. We do not We primarily use forward contracts, with maturities less than 4 months, to protect against the foreign currency exchange rate risks inherent in our forecasted transactions related to purchase commitments and sales denominated in various currencies. These derivative instruments are designated and qualify as cash flow hedges. The effectiveness of the cash flow hedges is determined by comparing the cumulative change in the fair value of the hedge contract with the cumulative change in the fair value of the hedged transaction, both of which are based on forward rates. The effective portion of the gain or loss on these cash flow hedges is initially recorded in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Once the hedged transaction is recognized, the gain or loss is recognized in our statement of operations.

Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Summary of Significant Accounting Policies We have identified the accounting policies and estimates that are critical to our business operations and understanding our results of operations. Those policies and estimates can be found in Note 1, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements and in “Critical Accounting Policies and Estimates,” in “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10 -K for the fiscal year ended March 31, 2019. Accordingly, this Quarterly Report on Form 10 -Q should be read in conjunction with our Annual Report on Form 10 -K for the fiscal year ended March 31, 2019. During the three month period ended June 30, 2019, there were no significant changes to any critical accounting policies or to the methodology used in determining estimates including those related to investment securities, inventories, goodwill, intangible assets, property and equipment, and contingencies other than those discussed below. During the three month period ended June 30, 2019, goodwill increased by due to foreign currency translation.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain amounts in the prior year consolidated financial statements have been reclassified to the current year presentation. The impact of the reclassifications made to prior year amounts is not material and did not affect net loss.
New Accounting Pronouncements, Policy [Policy Text Block]	Relevant New Accounting Standards In 2016, the FASB issued ASU 2016 - 02, “Leases”. This guidance changes the requirements for inclusion of certain right-of-use assets and the associated liabilities to be included in a statement of financial position. The Company adopted this guidance effective April 1, 2019, using the modified retrospective method and utilized the optional transition method under which the Company will continue to apply the legacy guidance in Accounting Standards Codification (“ASC”) 840, including its disclosure requirements, in the comparative period presented. In addition, the Company elected the package of practical expedients permitted under the transition guidance which permits the following: a) carrying forward the historical lease classification, b) not separating lease components from non-lease components within the Company’s facility lease contracts, c) not presenting comparative periods but rather recording a cumulative catch-up during fiscal 2020, and d) electing, by asset class, not to record on the balance sheet a lease whose term is twelve months or less including reasonably certain renewal options. As a result of the adoption of ASU 2016 - 02 for the fiscal year beginning April 1, 2019, the Company recorded initial operating lease right-of-use assets and operating lease liabilities related of and respectively. Right-of-use assets are included in “Other assets” on the Company’s Balance Sheet as of June 30, 2019. Lease liabilities are classified as current and non-current, and are included in “Accrued expenses” and “Other liabilities”, respectively, on the Company’s Balance Sheet as of June 30, 2019. Please refer to Note 2 for additional information. In June 2016, the FASB issued ASU 2016 - 13, “Financial Instruments – Credit Losses: Measurements of Credit Losses on Financial Instruments.” This standard requires the measurement and recognition of expected credit losses held at amortized cost. This new standard replaces the use of forward-looking information to estimate credit losses and requires credit losses for available for sale debt securities to be recorded through an allowance for credit losses rather than a reduction in the amortized cost basis. This update is effective for public companies for annual reporting periods beginning after December 15, 2019. Management is currently evaluating the impact of ASU 2016 - 13 on our consolidated financial statements. In August 2017, the FASB issued ASU 2017 - 12, “Derivatives and Hedging.” The standard aims to align the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results for cash flow and fair value hedge accounting with risk management activities. The guidance is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. Additionally, in October 2018, the FASB issued ASU 2018 - 16, “Derivatives and Hedging (Topic 815 ): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes”, which permits use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. This update is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. For entities that have not yet adopted ASU 2017 - 12, the concurrent adoption of ASU 2018 - 16 is required. The Company concurrently adopted ASU 2017 - 12 and ASU 2018 - 16 effective April 1, 2019. The adoption of these standards has not had a material impact on our consolidated financial statements. In February 2018, the FASB issued ASU 2018 - 02, "Income Statement - Reporting Comprehensive Income." This standard allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for any interim and annual financial statements that have not yet been issued. The Company adopted ASU 2018 - 02 effective April 1, 2019 and elected to not reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. The adoption of this standard has not had a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018 - 13, “Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement”. This standard removes, adds and modifies certain disclosure requirements in the existing framework. ASU 2018 - 13 removes the following disclosure requirements: (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy and (ii) the entity’s valuation processes for Level 3 fair value measurements. ASU 2018 - 13 adds the following disclosure requirements: (i) provide information about the measurement uncertainty of Level 3 fair value measurements as of the reporting date rather than a point in the future, (ii) disclose changes in unrealized gains and losses related to Level 3 measurements for the period included in other comprehensive income, and (iii) disclose for Level 3 measurements the range and weighted average of the significant unobservable inputs and the way it is calculated. ASU 2018 - 13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. We are currently evaluating the potential impact on our consolidated financial statements and disclosures. In August 2018, the FASB issued ASU 2018 - 14, “Compensation – Retirement Benefits – Defined Benefit Plans – General.” This standard removes certain disclosures that are not considered cost beneficial, clarifies certain required disclosures and added additional disclosures. The standard is effective for fiscal years beginning after December 15, 2020, and early adoption is permitted. The amendments in ASU 2018 - 14 would need to be applied on a retrospective basis. We are currently assessing the impact the new guidance will have on our disclosures. In August 2018, the FASB issued ASU 2018 - 15, “Customer’s Accounting For Implementation Costs Incurred In A Cloud Computing Arrangement That Is A Service Contract”. This guidance reduces the complexity for the accounting for costs of implementing a cloud computing service arrangement and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This update is effective for public companies for annual reporting periods beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company early adopted this standard effective April 1, 2019, utilizing the prospective approach to all implementation costs incurred after the date of adoption. The adoption of ASU 2018 - 15 has not had a material impact on our consolidated financial statements. We have reviewed other newly issued accounting pronouncements and concluded that they are either not applicable to our business or that no material effect is expected on our consolidated financial statements as a result of future adoption.
