Introduction

This article introduces the application field and working principle of BFC236642473 Film Capacitors. Film capacitors are capacitors commonly used in power electronics, electrical engineering and communications industries. They utilize thin plastic or paper films as the dielectric, and flat foil metal as the two electrodes.

Application Field

BFC236642473 Film Capacitors are widely used in switch-mode power supplies, power converters, dc/dc converters, and other electronic circuits as a power filter capacitors. They are also used to protect AC inverters, DC link circuits, and various types of electrical equipment.

Working Principle

The working principle of BFC236642473 Film Capacitors is based on the ability of a capacitor to store electrical energy between two conductors separated by a dielectric material. Film capacitors range in material from all plastic to oil-filled paper construction. The dielectric materials used in film capacitors range from polypropylene, polyester, polycarbonate, polystyrene, to highly specialized materials like polysiloxanes. The most commonly used film used is polyester or polypropylene.

A capacitor works by storing an electrical charge on the plates of the capacitor by allowing positive charges to build up on one side and negative charges to build up on the other. When voltage is applied to the capacitor, the positively charged plate is attracted to the negative plate and the electrical energy is stored. The electric field created by the voltage across the capacitor causes the electrons to move, resulting in a current, which in turn causes a charge to build up on the plates.

The capacitor has a wide range of operating temperatures and is able to withstand high levels of current. It also features high dielectric strength and low resistance, as well as low ESR and ESL values, making it ideal for high frequency circuits.
