Film Capacitors

A film capacitor, also known as a /polymer capacitor/, is an electrical component composed of two metal plates separated by a thin dielectric film. Film capacitors are used as capacitors in electronic circuits for purposes such as signal filtering, energy storage, and voltage conditioning. The BFC238661184 capacitor is one type of film capacitor that is finding a variety of applications.

Application Field

Film capacitors are popular for use in a variety of applications because of their relatively low cost, small size, high reliability and long life. The BFC238661184 capacitor is specifically designed for use in temperature sensitive applications and performs best in service temperatures between -25 °C and 85 °C. It is widely used in industrial controls, home appliances, white goods, computers, and multimedia. Its low ESR values and wide operating temperature range make it suitable for use in high-frequency electronic filters, and it is also applied to DC/DC converters, audio equipment, and telecommunication systems.

Working Principle

Film capacitors are composed of two metal plates that are separated by a thin dielectric film. The film is then sealed in a non-conducting case. When a voltage is applied across the two plates, an electric field is created which affects the charge distribution on the surface of the film. This causes electrons to be attracted to the positive plate and repelled from the negative plate, generating an energy storage load. The amount of energy stored in the capacitor is a function of the electric field intensity, the thickness of the dielectric film, and the area of the capacitor plates.

The BFC238661184 capacitor is made from a high-temperature epoxy-coated polyethylene terephthalate (PET) film. This material provides superior temperature stability and dielectric qualities which makes it highly suitable for temperature sensitive applications. Furthermore, the PET dielectric film provides high voltage intensity ratings, making it an excellent capacitor choice for use in moderate to high voltage power applications.

Film capacitors are economical, reliable, and long-lasting capacitors that can be used in a wide range of applications. The BFC238661184 capacitor exhibits particularly useful features for temperature sensitive applications, and its low ESR values and wide operating temperature range make it suitable for use in high-frequency electronic filters. With its long lifespan, excellent performance, and relatively low cost, the BFC238661184 has quickly become a popular choice for many around the world.
