KEMET Auto Grade Power Film Capacitors

This series of power film capacitors meet the requirements of AEC-Q200. The C4AQ series is suited for industrial, automotive and power supply designs for DC link, DC filtering and energy storage applications, while the C4AF series is suited for industrial, automotive, power supplier and energy storage applications for AC filtering.

The RoHS compliant capacitors have a polypropylene metallized film construction and are available as two or four radial leaded board mount devices. Available values for the C4AQ series range from 1.0 µF to 130 µF, with additional sampling for 170 µF and 210 µF. Voltage values span from 500 VDC to 1500 VDC. Devices from the C4AF series are designed for use in more demanding and harsh applications and are offered in capacitance values up to 62 µF with voltage ratings up to 400 VAC.

AEC-Q200 qualified devices within the C4AQ and C4AF ranges address the requirements of the increasing amounts of electronic content in automotive applications, where operating environments can be particularly challenging from both an electrical and environmental standpoint.
