Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a capacitor that uses plastic film as its dielectric. It usually consists of a metalized film, which serves as an electrode, and a wrap-around material of an insulating material such as polyester, polypropylene, aluminum oxide, polycarbonate, paper, etc., and electrodes leads. It has low losses, good frequency characteristics, and is mainly used in low-frequency circuits and power supplies.

MKP383247200JF02W0 Application Field and Working Principle

The MKP383247200JF02W0 film capacitors are specifically designed for high-frequency applications that require low loss and good frequency characteristics. These devices are typically used in applications such as resonators, DC/DC converters, drives, switching power supplies, and linear power supplies.

The MKP383247200JF02W0 film capacitor works by storing energy in the form of an electric field in the dielectric material that separates the two metalized plates. When a steady voltage is applied across the two plates, a certain amount of energy is stored in the form of an electric field. The higher the voltage applied, the more energy is stored and the bigger the electric field. When the voltage is removed, the capacitor quickly releases the stored energy as current.

The MKP383247200JF02W0 film capacitor has a wide range of applications due to its excellent electrical and mechanical characteristics. Its high capacitance, low inductance, low leakage current, high reliability, and long life make it ideally suited for applications requiring high performance such as AC/DC converters, drives, switching power supplies, and linear power supplies.

In addition to the DC applications, the MKP383247200JF02W0 film capacitor is preferred in RF circuits as a result of its low losses, low impedance, low inductance, and low parasitic effects. Its wide temperature range and its superior frequency characteristics make it an ideal choice for RF applications such as filters, oscillators, amplifiers, and antennas.

The MKP383247200JF02W0 film capacitor provides high power density as compared to ceramic capacitors and thus can be used in applications where the space is limited. The capacitor also offers excellent dielectric absorption and excellent stability in high temperature and high-humidity environments.

The MKP383247200JF02W0 film capacitor is also very cost effective due to its wide capacitance range, small size, long life, and good dielectric characteristics. The cost savings are even more pronounced when used in applications that require a high level of performance from the capacitor, such as power supplies and RF circuits.
