Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor that uses plastic film as the dielectric. It often consists of two or more windings of coated metal deposited on the film. Films are a good electrical insulator and low in cost. In contrast, the dielectric of ceramic capacitors is formed from a ceramic material. Film capacitors are especially suitable for use in applications with higher voltage ratings in comparison with ceramic capacitors, due to their higher dielectric strength.

MKP383318025JCA2B0 application field and working principle

The MKP383318025JCA2B0 film capacitor can provide a low ESR (Equivalent Series Resistance) and high-temperature stability for high-frequency applications. It is designed for a wide range of applications, including general circuit protection, power circuits, and RF circuits. The MKP383318025JCA2B0 is composed of two electrodes, two dielectrics, and two cases. The electrodes are typically made of copper and other metals. The dielectric is a plastic film such as polypropylene, polycarbonate, polyethylene, and polyester. The two cases are usually a metal shielding layer and a plastic body. The metal shielding layer is often used to reduce the electromagnetic interference. The plastic body provides a mechanical and electrical barrier.

In terms of working principle, the MKP383318025JCA2B0 film capacitor stores its charge in the form of electric field between the two electrodes. When a voltage is applied, the electric field stored in the film capacitor draws electrons toward the positive electrode and away from the negative electrode, resulting in an effect called electrostatic induction. The MKP383318025JCA2B0 can also be used as an energy source through a charging and discharging cycle. During the charging phase, the positive electrode will create an electrostatic field to draw electrons from the negative electrode into the capacitor. During the discharging phase, the electric charges will be released from the positive electrode to the negative electrode.
