Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor consisting of a thin film of plastic as the dielectric material with two electrodes running parallel with the film. These capacitors combine a wide range of values and a low loss of capacitance in a variety of chemical compositions and dielectric materials.

In film capacitors, the electrodes are usually made of Aluminium or Copper foil. The dielectric layer can range in thickness from a few Angstroms to several microns, which gives them a much higher capacitance-to-volume ratio than solid-state capacitors. The dielectric material, known as the insulating medium, can be any of a variety of polymers or plastics such as polystyrene, polypropylene, and polyvinylidene fluoride.

The working principle of the MKP1840547405M capacitor is based on the principles of capacitance, which involves the ability of a capacitor to store energy in an electric field. The capacitor consists of two metal plates separated by an insulating material, referred to as the dielectric. When an electric current is applied to the plates, an electric field is created, which stores energy.

When the electric current is removed, the electric field is reduced, and the capacitor discharges its energy. The energy stored in a capacitor is equal to the electric field times the area of the capacitor plates. The size of the capacitor is determined by its ability to store a certain amount of energy for a given voltage.

This makes the MKP1840547405M capacitor an ideal choice for applications requiring a low ESR and high capacitance values. It is well suited to audio, video, and electric motor drive systems, as well as for use in switching power supplies and pulse circuits.
