Power Film Capacitors for Demanding High Power, High Frequency Applications

June 06, 2018 by Paul Shepard

KEMET announced two new series of power film capacitors that 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 addresses similar applications, but is specifically designed for harsh environments.

The new 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 1.0µF to 130µF, with additional sampling for 170µF and 210 µF. Voltage values span from 500Vdc to 1500Vdc. Devices from the C4AF series are designed for use in more demanding and harsh applications and are offered in capacitance values up to 62µF with voltage ratings up to 400Vac.

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°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,” Scagliarini added.

Visitors to PCIM Europe (June 5 – 7, Nuremberg) can see the new capacitors, plus KEMET’s wide range of component solutions at Hall 9, Stand 403.
