Film Capacitors

A film capacitor, also known as a plastic or poly film capacitor, is a type of capacitor that uses an organic polymer film as its dielectric layers. The film, which is the active component of the capacitor, is made of polymer materials such as polyester, polypropylene, and polycarbonate. Other types of materials such as metals, alloys, and ceramics can also be used as the dielectric layer. The active components of the film capacitor are then wrapped within an insulating material. Other types of capacitors usually use metalized layers, while some use dielectric materials such as glass or plastic films that are thicker than film capacitors.

The BFC233860823 film capacitor is a high-performance device designed for a range of applications in a wide variety of industries. It is mainly used in high-voltage filters and controllers, as well as medical and automotive components. This capacitor is especially suitable for applications that require a high ripple current tolerance, as it has low ESR and also good temperature cycling performance. It has a rated voltage of 440VAC and a rated capacitance of 8200pF. This capacitor is also suitable for use in power electronics, telecommunications, signal filters, and high-power control systems.

Working Principle

The working principle of the BFC233860823 film capacitor is based on the concept of dielectric polarization. When an alternating voltage is applied on the capacitor, the dielectric material of the film will create a charge separation or dipole. This dipole will induce an electric field between the two electrodes, resulting in current flow. This current flow can either charge or discharge the capacitor. The charge and discharge current is then measured in order to determine the capacitance of the capacitor.

When an alternating voltage is applied, the film will result in the development of a small potential difference that creates a dielectric polarization. This polarization, in turn, will create a capacitive reactance. As the frequency of the applied voltage increases, the capacitive reactance will also increase. This increase in capacitive reactance will result in a decrease in current flow, eventually leading to a high capacitance. The higher the capacitance, the better the performance of the capacitor.

The BFC233860823 film capacitor is designed to provide high voltage protection in a wide variety of applications. It is particularly suitable for use in power electronics, telecommunications, signal filters, and high-power control systems. This capacitor offers good temperature cycling performance, excellent resiliency to shock and vibration, as well as low ESR over a wide temperature range.
