Power film capacitors target harsh environments

June 10, 2018 // By Nick Flaherty
Kemet has launched two new series of power film capacitors at PCIM this week that meet the requirements of AEC-Q200 for industrial and rugged designs.

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 addresses similar applications, but is specifically designed for harsh environments.

The RoHS compliant capacitors have a polypropylene metallized film construction and are available as two or four radial leaded board mount devices. The C4AQ series ranges from 1.0 µF to 130 µF, with additional sampling for 170 µF and 210 µF. Voltages span from 500 VDC to 1500 VDC 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.

The capacitors are 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. They also have high ripple current values, high capacitance density and high contact reliability with an operating temperature range is -55°C to +105°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.”
