IEC TS 63337

This Technical Specification is developed under the leadership of Mr. Walter Huck (Germany) with participation of experts from China, USA, Finland, Germany, and Japan. A committee draft was circulated in April 2022 (40/2946/CD). After thorough discussions DTS has been circulated in October 2023 as 40/3093/DTS and the voting ends 2023-12-22.

The project is based on a document prepared by the “ZVEI/ECPE Film Capacitors Core Group” working group with representatives from the automotive, the device and the capacitor manufacturers.

It provides requirements, test conditions and tests to validate characteristics including the service life of application-specific film capacitors for use in motor vehicle drives DC-Link applications.

The requirements, test conditions and tests listed in this document apply to application-specific 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. The qualification requirements may be expanded or adapted for the application of technologically innovative designs if necessary. The content and scope of supplements shall therefore 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. Because the AEC-Q200 is not applicable for the capacitors considered here, this document defines a set of tests to ensure the basic suitability of the capacitor for this use.
