Working Principle

A film capacitor consists of two metal plates, metallic or foil electrodes separated by a film dielectric. The electrodes can be connected to either side of the external circuit. When electrical charge is applied to the capacitor, an electrical field is established between the electrodes, creating an electric potential difference between them. When the voltage is zero, the charge density is also zero. When the voltage is increased, the charge density increases.

The capacitance of a film capacitor is determined by its dielectric material, which is usually polyester. The capacitance is determined by the area of the electrodes and the thickness of the dielectric layer, as well as the relative dielectric constants of the dielectric material and the surrounding medium. The capacitance of the BFC237028123 is relatively constant over a specified temperature range.
