Film Capacitors

Film capacitors are a type of capacitor that relies on a thin film of polyethylene or polypropylene dielectric material, which provides excellent electrical insulation. They are also referred to as “plastic film capacitors” or “polyester capacitors” due to their reliance on a plastic dielectric material. Film capacitors are widely used in many applications, from start-up capacitors for motors to control capacitors for power lines and energy storage devices. The MKP385447040JIP2T0 is an example of a film capacitor.
