Film Capacitors

A film capacitor is an electrical component constructed with a film as the dielectric. It is a construction form of capacitors wherein the dielectric is a plastic film. It is a type of capacitor that uses a thin plastic film as the dielectric, in contrast to the traditional Medium and High Voltage Capacitor (MV & HV capacitor) which uses an oil-filled paper dielectric.

One of the most common applications of film capacitors is in its usage as energy storage. Energy storage capacitors are used in a wide range of applications. Common uses include power conditioning, surge suppression, voltage balancing, current limiting, settling and filtering.

BFC237052472 Application Field and Working Principle

BFC237052472 is a type of film capacitor specifically designed for military and aerospace applications. It is a low-profile, dual-ended polarized capacitor with an extended temperature range and high inductance. The BFC237052472 is an excellent choice for applications where extreme temperature and vibration are required, such as in aircraft avionics, missiles, and portable equipment.

The BFC237052472 is designed to work in high-temperature, high-vibration, and other specialized applications. It is constructed with a film of high-k dielectric material, and two electrodes of either metal film or woven conductive polymer material.

The working principle is simple. When the capacitor is connected to a power source, electrons from the positive terminal accumulate on the bottom plate. At the same time, electrons from the negative terminal accumulate on the top plate. This creates an electrical field between the two plates which stores the energy of the current. As the voltage across the capacitor increases or decreases, the electric field strength varies and the amount of energy stored in the capacitor also changes.

The BFC237052472 is also equipped with a thermal protection feature. This feature shuts off the capacitor when the temperature rises above a predetermined level, preventing it from overheating. This is important for safety and ensures that the capacitors are not damaged during use.
