KEMET C4A Radial Film Capacitors offer low ESR, resulting in a much higher ripple current rating without sacrificing capacitance. These products come in two styles: a polypropylene metallized film capacitor, a polypropylene metallized film, and a polyester double-metalized foil capacitor. Both versions have a rectangular, plastic box-type design, filled with resin, and use 2 or 4 tinned wires. KEMET C4A Radial Film Capacitors with high voltage ratings are ideal for DC-Link and high-power applications. Capacitors with a combination of low ESR, efficient CV, and high voltage rating are useful for energy storage and EMI filtering.
