Film Capacitors

BFC238301225 application field and working principle relates to the area of film capacitors. Film capacitors are gaining more attention due to their superior performance in high and low range frequencies and high insulation resistance. The design of a film capacitor consists of two metalized layers separated by a film dielectric of polypropylene, polyester, polycarbonate or more exotic materials.

Working Principle

At its simplest, a film capacitor works like a small-sized version of an electrical transformer. It stores electrical energy the same way, but typically operates at higher frequencies and higher voltages than a transformer. A film capacitor has two layers of metalized plastic film separated by a thin layer of dielectric material, usually a thin layer of polypropylene or polyester. The metalized layers act as the two conductors, while the dielectric material acts as a separator. As the capacitor is charged, the electric field between the two layers builds up, creating an electrostatic capacitance.

Application Field

Films capacitors are used in a wide range of applications, from consumer and industrial to military and aerospace applications. Typical applications include power supplies, audio amplifiers, switching and RF power amplifiers, decoupling, signal processing and in specific applications like antenna matching networks and pulse forming networks. Film capacitors are also used in high and low power applications, especially in high frequency operations, because they offer high dielectric strength, low inductance and a low current leakage.
