BFC238581362 Application Field and Working Principle

Film capacitors, also called polypropylene capacitors, are a group of capacitors formed by winding two layers of plastic film around a cylindrical, nonconductive core. These capacitors can have both high voltage and high capacity, and are usually used in filter networks and pulse applications, low frequency, as well as resonant circuits.The BFC238581362 film capacitor is an high-range device specifically designed for use in high line filter, voltage stabilizing, and frequency converters.

Working Principle

Film capacitors, such as the BFC238581362, usee two layers of plastic film as their dielectric. The two films are thin and light-weight, and their shape is often compared to a cylinder when viewed in cross section. One of the layers is etched with an electrode pattern of closely spaced metal traces, which are separated by thin insulation layers. When the two layers of plastic film are wound together on a nonconductive core, the resulting device can provide high capacitance with high voltage rating.
