They are relatively cheap, stable over time and have low self-inductance and ESR, while some film capacitors can withstand large reactive power values.
Its structure is made of “Plastic Films.” These films are made to be very thin. Once the “Film drawing procedure” is done, the created film can be coated with a metal or left as is, depending on the use. The generic method of development for these capacitors begins with the removal of a thin layer of plastic film.
Vishay film capacitors uses the following film materials in their production: Polyester film offers a high dielectric constant, and a high dielectric strength. It has further excellent self-healing properties and good temperature stability. The temperature coefficient of the material is positive.
Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
Although the materials and construction techniques used for large power film capacitors are very similar to those used for ordinary film capacitors, capacitors with high to very high power ratings for applications in power systems and electrical installations are often classified separately, for historical reasons.
The characteristics of a film capacitor, and the situations in which the capacitor can be used, will vary greatly depending on the type of dielectric used. For example, a PP film capacitor provides excellent self-healing and high reliability, and is therefore often used in fields such as vehicle-mounted equipment and industry automation.
