BFC236942563 is a commonly used film capacitor that can be used in many application fields. It is mainly suitable for air conditioners, refrigerators, washing machines, pumps, transformers and other household appliances, as well as various climate control systems and medical devices.

It can also be used in power supply systems, commercial and industrial equipment, communication and instrumentation equipment, consumer electronics, electrical vehicles, and other electronic products.

Working Principle

The working principle of a film capacitor is relatively simple. It is made up of two electrodes separated by a thin dielectric material. The electrodes are usually either metal or aluminum, while the dielectric material is usually a polypropylene film. When a voltage is applied across the electrodes, an electric field is created within the dielectric material, which is proportional to the applied voltage.

The electric field causes electrons to move, and the electrons that cross the dielectric are attracted to the opposite electrode and create an electric field there. This electric field creates a charge on the second electrode, which is then opposite in polarity to the voltage applied across the electrodes. This charge causes electrons to move from the opposite electrode back across the dielectric to the first electrode, and so forth.

This creates a back-and-forth flow of electrons, which is known as Capacitance and is measured in Farads. By changing the distance between the electrodes and adjusting the dielectric material used, the capacitance of a film capacitor can be adjusted to meet the needs of the application.
