Film Capacitors

Film capacitors, also known as plastic film capacitors, polypropylene film capacitors, or film dielectric capacitors, are non-polarized capacitors characterized by their light weight and relatively small size. Film capacitors are generally used in applications where high reliability, small size, low leakage current, and low loss are primary requirements. They have become increasingly popular in recent years as a cost-effective alternative to ceramic and electrolytic capacitors in various consumer and industrial electronic applications.

The MKP1841222135 is a type of film capacitor, which is a non-polarized capacitor formed by applying a thin layer of plastic film onto a substrate, which is then insulated with a dielectric layer. In addition, the electrodes are then formed onto the substrate.

Application Field and Working Principle

The MKP1841222135 is often used in radio frequency (RF) circuits and in the production of printed circuit boards. It is a good replacement for ceramic capacitors due to its low cost and its small size. The MKP1841222135 can also be used for high frequency applications such as digital filters, filter amplifiers, and oscillators.

The working principle of the MKP1841222135 is based on the principle of capacitor voltage division. When a voltage is applied across the capacitor, the electrical field generated by the voltage creates an electrostatic field across the insulating dielectric layer of the MKP1841222135. The voltage across the capacitor then divides the electrostatic field resulting in a lower voltage across the capacitor. This lower voltage results in less current flowing through the capacitor.

The MKP1841222135 is a reliable film capacitor that is often used in a variety of applications. Its small size and low cost make it an ideal choice for cost-sensitive applications. Furthermore, its low leakage current and low loss makes it an attractive choice for high frequency applications such as digital filters, filter amplifiers, and oscillators.
