DC Link (Automotive Grade) Power Film Capacitors – C4AU Series
KEMET harsh-environment polypropylene metallized film capacitors are designed for DC filtering and DC link applications
KEMET, a YAGEO group company, offers DC-link capacitors that act as an intermediary DC smoothing stage between AC stages. The intermediate DC step allows noise-reduced power transfer when converting between AC sources of different power, voltage, or frequency conditions. The C4AU series is a polypropylene metallized film capacitor with a rectangular, plastic box-type design, filled with resin. These capacitors are intended to withstand harsh environmental conditions and are automotive grade AEC-Q200 qualified.
DC-link capacitor applications include power inverters, motor drives, and high-power charging circuits.
