Film Capacitors

A film capacitor, also known as a plastic film capacitor or film dielectric capacitor, is an electrical capacitor with a nonconductive film as its dielectric, usually polyester, polypropylene and polystyrene. Film capacitors can have either vertically mounted plates or flat, parallel terminals. With vertical mounting, the capacitor terminals are connected to the opposite faces of the film, with flat terminals the connection is made in the same direction.

685PHC400K application field and working principle

The 685PHC400K film capacitor is a low profile, high voltage application that is suitable for audio, pulse, frequency and up to 4kV dc applications. It is also suitable for use in high voltage and high temperature applications, where space and high frequency response is an issue. Due to its low profile and capacity, this capacitor is ideal for applications where space saving is required.

The 685PHC400K film capacitor works by using a thin dielectric film that is usually made of polyester (PET), polypropylene (PP) or polystyrene (PS). This film acts as an insulator between two conducting plates. The electric field between the two plates is increased when a voltage is applied across them and the charge is stored in electric form. The capacitor is able to store electric charges that are released slowly as soon as the voltage is taken off from the plates.
