Advance Capacitors being one of the oldest designing and production company of capacitors, that has been working since 30+ years has produced thousands of variety dry/plastic film capacitors and served more than 800 clients ensures to maintain its high level of production by serving as many clients as possible.

Dry/Plastic film capacitor, also known as film dielectric capacitor is highly used to construct the aluminum/zinc and dielectric electrodes of the capacitor. This capacitor is used to store electric charge as electrodes and it is mainly used in the places where high insulation resistance with low loss is required.

Types of Dry/Plastic Film Capacitors :

  • Film-Foil Capacitors
  • Metallized Film Capacitors

Film-Foil Capacitors :

Film-foil capacitors are made of two layers of aluminum foil that act as electrodes and is divided by the plastic sheets that act as a dielectric. The aluminum foil and plastic sheets are rolled to cylindric shape and wire leads are directly welded to both the sides of aluminum foil of the capacitors. In film-foil capacitors, polyester, polypropylene, polyethylene terephthalate, and polyphenylene sulfide are usually used as a dielectric.

Metallized Film Capacitors :

In contrast to film-foil capacitors, metalized film capacitors are made of an extremely thin layer using metal vacuum-deposited straightly on the dielectric film layer. The wire lead of these metalized film capacitors is attached to the metal layer and metal spray is applied to both the ends.
