Film Capacitors Application Field and Working Principle

Film capacitors, also known as film dielectrics, are electrical components having a dielectric value according to the thickness of the insulation. BFC236725154 Film capacitor is an outstanding product from the family of film capacitors. They are widely used in industrial, automotive, communications, lighting, military, and aerospace applications due to their advanced features and highly reliable performances that meet the current market needs and expectations.

Typical Application Areas

BFC236725154 film capacitors can be used in various power conversion, control, and switching applications such as DC/DC converters, inductive heating controllers, general purpose AC/AC power supplies, as well as several other types of power related products deployed in various household, commercial, and industrial applications. They are widely deployed in transformers, motor speed controllers, air conditioning and heating systems, lighting systems, and other applications involving safety and power control.

Working Principle

A film capacitor generally consists of an insulating film sandwiched between two metal foils (generally aluminum). The film capacitor is formed by numerous layers of insulating film, with each layer separated by electrode. When an electric charge is applied across the two electrodes, the resulting current is confined to a very thin layer due to the high dielectric constants of the insulating film (typically 10 to 30 times that of air). The amount of charge transferred to a film capacitor at any one time is determined by the size of the dielectric gap. When the dielectric gap is too thin, the voltage drop across it will not be sufficient to support a sufficient current flow. Therefore, by controlling the dielectric gap, the amount of current that can be transferred is also controlled.
