Working Principle of BFC238320393 Film Capacitors

BFC238320393 film capacitors are constructed from a sandwich of two metalized plastic films, such as polyester or polypropylene, with electrodes on both sides. The electrodes create an electric field between the two films which is used to store electrical energy. When a voltage is applied across the electrodes, a charge is stored in the electric field. This charge can then be released when a higher voltage is applied.

The capacitance of BFC238320393 capacitors is determined by the physical size of the capacitor and by the spacing between the electrodes. A larger capacitor with more space between the electrodes will have a higher capacitance than a smaller capacitor with less space. The capacitance of these capacitors also varies with temperature, making them suitable for temperature compensation circuits.

BFC238320393 capacitors have low leakage current, high temperature stability, and excellent insulation characteristics, making them suitable for a wide variety of applications. They are available in a range of CASE sizes for a variety of voltage and current ratings.
