Product Description
Product Overview
The MMKP82 is a double-sided metallized polypropylene film capacitor (box-type) designed for high voltage and high-frequency pulse circuits. It features a polypropylene film dielectric, metallized polyester film electrodes with excellent self-healing properties, and a non-inductive configuration. This capacitor is widely used in electronic ballasts, energy-saving lamps, and SNUBBER and SCR commutating circuits. It offers low loss, small inherent temperature rise, a negative temperature coefficient of capacitance, and excellent flame resistance.
