Polypropylene film capacitors belong to the category of organic film capacitor. Its dielectric is polypropylene film. There are two types of electrodes: metal sink type and metal film type. The coiled capacitor core is encapsulated with epoxy resin or packed into plastic and metal casings. In the package. Polypropylene capacitor made with metal film electrodes are called metallized polypropylene film capacitors.

Polypropylene film capacitor have the following characteristics:
①The capacity range is wide, ranging from thousands of picofarads to tens of microfarads.
②Good temperature resistance and high insulation resistance.
③Metalized polypropylene film capacitor have good self-healing ability.
④The loss tangent value is small, and the high frequency characteristic is good.
⑤Small size, reliable work.

Polypropylene film capacitor can be used to replace paper and mica capacitor. They are mainly used in AC, laser, coupling, filtering and compensation circuits, and are widely used in household appliances.
