Filter Capacitors with Heightened Capacitance Densities & Prolonged Operational Lifespan

20 October 2023

Available via the Rutronik distribution network, the C4AF-F filter capacitors from KEMET are more compact and have greater longevity than the manufacturer’s previous generation.

They have a robust metallised polypropylene film construction, and are intended for use in the harmonic filtering in uninterruptible power supply (UPS) units and industrial motor drives, as well as inverter systems and charging equipment. As they are AEC-Q200 compliant, their deployment in automotive systems is also applicable. Their temperature-humidity-bias (THB) has been extended to a period of 1500 hours (at a temperature of 85°C and with 85% relative humidity). By increasing the capacitance density, capacitance values reaching 75µF are now supported.
