Application Fields

BFC238321914 film capacitors can be applied in a wide range of applications, including power factor correction, energy storage, power transmission and distribution, high voltage switching, etc. Besides, they are also used in integrated circuits (ICs), power supplies, video amplifiers, high-end audio equipment, medical equipment, telecommunication equipment, smart electrical circuitry and other electrical equipment.

Working Principle

The working principle of the BFC238321914 film capacitor is based on the dielectric effect. The dielectric material of the capacitor can absorb electric charges and separate it from the outside environment and store electric charges on the plates. When voltage is applied across the capacitor plates, an electric field is produced in between two plates which induces electric current to flow, generating energy stored in the capacitor. Since the electric field moves cyclically, it can continuously supply energy. In this way, BFC238321914 film capacitors can perform several different functions, such as energy storage, voltage conversion, phase shifting, and signal filtering.
