Film Capacitors

A film capacitor, sometimes also called a plastic film capacitor, is a capacitor that uses a film of plastic as the dielectric (insulation). The plastic film is usually polyester, polypropylene, or polycarbonate. Other dielectric films, such as polyphenylene sulfide, polyetherimide, and Kapton, are also used. Film capacitors are primarily used in power systems and signal processing due to their high tolerance to temperature & chemical stability as compared with other types of capacitors.

The BFC238343392 is a film capacitor, designed for medium frequency applications. This product line has a voltage rating of 450V (BFC238343214 and BFC238343314) and 250V (BFC238343213 and BFC238343313). It is a radial-leaded product, made of metallized polyester film, and is compliant with IEC60384-14 AC & AEC-Q200 standards.

Working Principle

The BFC238343392 film capacitor consists of two electrodes (anode and cathode) and an insulating polymer film, or dielectric, sandwiched between them. The dielectric material is usually a polyester or polypropylene which is highly resistant to breakdown and offers superior temperature and environmental stability. The capacitor charges when an electrical current passes through the electrodes. This electrical current is stored in the dielectric material until it dissipates.

The dielectric\'s ability to store energy is based on the electron displacement phenomenon. When an external electric field is applied to the electrodes, the electric field induces an electric charge on the dielectric material. This electric charge causes electrons to move from one electrode to the other, and the charge is "captured" by the dielectric material. The amount of charge stored depends on the capacitance, which is the ratio of charge to voltage.
