Two series of power film capacitors target demanding high frequency applications

Two new series of power film capacitors that meet the requirements of AEC-Q200 are now available from Kemet. The C4AQ series suits industrial, automotive and power supply designs for DC link, DC filtering and energy storage applications, while the C4AF series addresses similar applications, but is specifically designed for harsh environments.

The new RoHS compliant capacitors have a polypropylene metallised film construction and are available as two or four radial leaded board mount devices.

Available values for the C4AQ series range from 1.0-microF to 130-microF, with additional sampling for 170-microF and 210-microF. 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 microF 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.

Kemet’s new power film capacitors are well suited for increasingly common high frequency applications. The capacitors are housed in rectangular, resin filled enclosures and deliver an array of application benefits including self-healing characteristics and low losses. High ripple current values, high capacitance density and high contact reliability are additional features of the new devices. The operating temperature range of the power film capacitors is -55 degrees C to +105 degrees C.

“Our new power film capacitors have been developed to provide a robust and reliable solution in high power, high frequency applications for challenging end uses,” said Fabio Scagliarini, Kemet vice-president of film and filter business development. “We continue to leverage our extensive experience and technical expertise to design and introduce capacitive and other passive component solutions that address the evolving and increasingly stringent demands of the automotive and industrial sectors.”
