Product Overview
The MMKP82 series is a box-type, double-sided metallized polypropylene film capacitor designed for high-frequency DC and pulse applications in electronic equipment. Featuring a non-inductive winding structure, these capacitors are suitable for absorption and resonance circuits. They are encapsulated in a flame-retardant plastic case and epoxy resin, ensuring good dimensional consistency and low loss with minimal internal temperature rise. Typical applications include switching power supplies, electronic ballasts, motor control, and TV vertical deflection circuits.
