MKP386M Snubber Polypropylene Film Capacitors Vishay Roederstein MKP386M Series Snubber Metallized Polypropylene Film Capacitors were designed to reduce voltage and current spikes caused by switching of IGBTs. The MKP386M snubber metallized polypropylene film caps from Vishay also reduce EMI by clamping voltage and current ringing. Features include capacitance range from 0.047µF to 10µF, voltage range from 700V to 2500V, compact design, high pulse strength, low-inductance construction (low ESL), and low ESR.
