PT TS 63337
Basic qualification of DC-Link film capacitors for automotive use; General requirements, test conditions and tests
The document IEC TS 63337 was published in February 2024, and is now going to be implemented into supply specifications for customized DC-Link capacitors, mainly in the voltage range between 450 V DC to 1200 V DC.
This Technical Specification was 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 ended 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.

Passive filter units for electromagnetic interference suppression
MT 60940
Guidance information on the application of capacitors, resistors, inductors, and complete filter units for electromagnetic interference suppression
The maintenance team for the edition 3 of the document has been established in January 2021. The convenor is Dr. S. Weber (Germany) and members from Japan, Switzerland, and Finland. The maintenance work started during the year 2021. The number of applications for this kind of components have been increasing after the publication of the previous edition of this document, and new requirements have appeared.
The intention in the maintenance work is to collect from component and equipment standards, and from actual applications, the guidance, how the components are/can be used in various applications and how they possibly can substitute each other taking especially the safety aspects into consideration. This kind of guidance has been requested e.g., by ACOS.
The intention is to restructure the document totally and make it a normative one, so that it can be referred to in the Safety standards. The project has been delayed because of the complexity of the task. The commenting to CD ended 2024-10-25, and CDV has been prepared. It will be circulated for voting in March 2025.
