B32529C0222J189 Application Field and Working Principle

Film capacitors, also known as film dielectric capacitors and plastics film capacitors, are a type of capacitor which is mainly composed of film dielectric and metal plates, with a tin-plated or silver-plated conductor in the middle. As a kind of capacitor with a wide range of applications, film capacitors are designed by winding a cellulosic film, combined with a bonding layer, around an internal core separating two metal layers. Its working principle is mainly due to the electrical double layers being formed in the dielectric of the two separate electrodes, thus providing an electrostatic energy storage in the capacitor.
