Film capacitors, or film dielectric capacitors, are capacitors of which the dielectric is a film of plastics like Mylar and nylon. Film capacitors are available in a variety of styles and configurations from 0.1pF to hundreds and even thousands of microfarads. BFC238660154 is a film capacitor specifically designed for high-frequency noise-suppression application in frequencies lower than 6.5MHz.

Application Field of BFC238660154

BFC238660154 utilizes polyester and PP film as the dielectric material, forming a single-piece construction for long-term stability even under high temperature and humidity. Its metallized surfaes on the top and bottom side act as plates of a capacitor, mainly used in applications like high precision noise suppression, audio filtering and AC coupling applications.

BFC238660154 can be used to reduce power-line noise, eliminating radiated interference from the capacitors. It is also suitable for low-voltage and high-frequency noise suppression applications in the automotive industry, communication base stations, TVs, and telephones.

Working Principle of BFC238660154

BFC238660154 works by storing electric charge, and thus electric potential energy, in an electric field. The effect is the same as two small metal plates separated by a thin dielectric material. When a voltage is applied across the plates, the electric field between the plates increases, and the capacitor stores electric charge on one plate and induces an equal and opposite charge on the other.

When a current flows through the capacitor, the electric field between the plates decreases and the induced charge is neutralized, allowing the charge to flow back and forth. This process is known as electric polarization and the capacitance is determined by the size of the plates and the dielectric strength of the material between the plates.

BFC238660154 has a temperature coefficient of capacitance that is relatively low, allowing it to maintain its capacitance even under a wide temperature range. It also has a low resistance over a wide range of temperature and voltage, which allows it to be used in high-frequency applications with minimum energy loss.
