IEC TS 63337:2024

IEC TS 63337:2024 provides requirements, test conditions and tests to validate characteristics including the service life of customized DC-link film capacitors for use in motor vehicle components. Standard DC-link capacitors qualified according to other IEC standards or AEC-Q200 are excluded from the scope of this document. The requirements, test conditions and tests listed in this document apply to customized film capacitors developed for use in motor vehicle power electronics for the application as a DC-link capacitor in HV applications or in the intermediate circuit of the 48 V on-board electrical system. These qualification requirements can be expanded or adapted for the application of technologically innovative designs, if necessary. The content and scope of supplements is therefore to be specified and documented in coordination between the responsible parties prior to sourcing. Power electronics in the motor vehicle need to be tested in accordance with the environmental qualification standards of the vehicle manufacturers. The tests in this document do not replace the tests specified in the Component Requirement Specifications for complete vehicle components or additional or deviating further requirements, test conditions and tests described therein. This document contains no tests to validate the thermal interface between capacitors, power electronics and the cooling system on the component level.
