What qualifications do capacitor manufacturers need to possess?1.
The tests described in the following are intended to validate the characteristics and service life of capac-itors for use in the vehicle. The basis of the specified tests are the current-ly-known failure mechanisms and the motor vehi-cle-specific application profiles of power electronics.
This specification defines the general requirements for the qualification approval, procurement, including lot acceptance testing, and delivery of Capacitors and Capacitor Filters, Feedthrough suitable for space application.
Because the AEC-Q200 is not applicable for the capacitors con-sidered here, this requirements document defines a set of tests to ensure the basic suitability of the capacitor for this use. A vehicle with an electric power train is typically described with the following design service life parameters.
