Film Capacitors

Film capacitors are an important type of capacitors used in electronics, and the BFC238553222 is one of the most popular and widely used varieties. This film capacitor is usually a plastic film capacitor (PFC) with a dielectric configuration of two or more overlapping conductive surfaces, often connected to an external reference or an interlayer dielectric. The dielectric material can be plastics, such as polypropylene (PP), polyvinylidene fluoride (PVDF), polycarbonate (PC), or polyester (PE).

Application field

The BFC238553222 is designed for use in electrical and electronic systems. This film capacitor can be found in a wide variety of applications, including power factor correction (PFC), audio decoupling, example, power supplies, auto sensors, electronic ballasts, and DC/DC converters. It is also used in audio systems, telecommunications equipment, motors, and oscillators, as well as in medical electronics and industrial equipment.

Working principle

A film capacitor works by creating an electric field between its two or more conductive surfaces. This electric field is produced by an electric charge, either positively or negatively charged, which creates an electrostatic shield that permeates the plastic or other dielectric between the two conductive surfaces. When a voltage is applied, it charges the plates with opposite charges, creating an electric field in the dielectric between the two plates. The electric field causes a current to flow, which is the basic principle of the film capacitor.

The BFC238553222 film capacitor is a direct-acting, self-healing, Class X1/Y1 film capacitor with a voltage rating of 250VAC and a capacitance range of 1.2μF to 0.3μF. Its direct-acting design is capable of self-healing, providing long-term stability and reliability, and its terminals are marked for easy identification. The combination of high dielectric strength and excellent temperature characteristics makes the BFC238553222 perfect for use in a wide range of applications.
