Film Capacitors

A film capacitor, also known as a plastic or polymer capacitor, is a type of capacitor which uses a thin plastic film as dielectric and aluminum, zinc, or other metal alloy foil, or aluminized polyester or polypropylene film, as its electrodes. This type of capacitor can be divided into two types according to its structure: Fixed film capacitor and variable film capacitor. MKT1820368254 is one type of fixed film capacitor.

It has a low reactance and a large capacity, so it has excellent damping DC and AC signals, so it is often used in high frequency rectification filter circuit and related filtration circuit.MKT1820368254 is also suitable for long-term storage and filtering in speaker, recorder and radio.More commonly, MKT1820368254 film capacitors are usually used in power supply circuit, filter circuit, frequency selection circuit, decoupling circuit, high frequency by-pass circuit, high frequency oscillation circuit and other electronic circuits.

MKT1820368254 Working Principle

The MKT1820368254 film capacitor consists of a dielectric without any jagged edges and two electrodes on both sides. It is formed by sandwiching a plastic film. When the electrodes are energized, the electric field is generated, and the electric potentials of the two electrodes control the electric charge density. When the applied voltage is AC, the capacitance of the capacitor will remain constant, because the two electrodes can react quickly according to the potential difference to adjust the charge density, thus forming a relatively stable capacitor.

The dielectric of the MKT1820368254 capacitor comes in many forms, such as PET, PEN, PO, PP, PPS, polystyrene, etc. With the optimization of the dielectric material, the capacitance ranges from 0.01pF to 1μF, and the working voltage ranges from 6V to 660V.
