Introduction to Film Capacitors

Film capacitors, also known as plastic film capacitors or foil capacitors, are a type of capacitor having a dielectric of plastic film. Generally, they include polypropylene film capacitors, polycarbonate film capacitors, polyester film capacitors, polystyrene film capacitors, and cellulose film capacitors. Commonly used dielectric materials are polypropylene, polyester, polycarbonate, polystyrene, and cellulosic. The capacitance values of film capacitors range from 0.001 pF to 0.47 microfarad in a leaded body and to 10F in a Radial Molded body.

Application Field of MKP385413040JFM2B0

MKP385413040JFM2B0 is a type of film capacitor that has the features of high voltage proof, temperature stability, good insulation, low dissipation factor, and long service life. It is widely used in broadcasting and electronics industry, such as power supply, switching power supply, transformers, motors, capacitor filtering, energy storing, signal processing, inverters etc. It is also widely used in high voltage industry, such as high voltage electric power transmission and distribution networks, HVDC circuit, substations, transformers etc.

Working Principle of MKP385413040JFM2B0

A film capacitor is an electronic component made of two pieces of metal with a thin insulating film coating between them. The most common form of film capacitor is made from two thin layers of metal foil, each wrapped around a roll of plastic or paper film. The film acts as the dielectric and insulates the two layers of metal foil.The film capacitor works on the basic principle of a capacitor, where one plate of the capacitor stores charge and the other plate discharges it. This same principle applies for a film capacitor. As electrons flow between the two plates of a film capacitor, capacitance is created. The film capacitor’s capacitance value is determined by the distance between the plates, the size of the plates, and the dielectric constant of the film.As the voltage across the film capacitor increases, the electric field across the film increases and the capacitance decreases. This is due to the dielectric material becoming less effective as the electric field strength increases. This phenomenon is referred to as capacitance loss or dielectric absorption, and is the reason why film capacitors are more prone to voltage spikes than other types of capacitors.

Conclusion

As we discussed above, MKP385413040JFM2B0 is a type of film capacitor that has the features of high voltage proof, temperature stability, good insulation, low dissipation factor, and long service life. It is primarily used in high voltage industry, broadcasting and electronics industry. It works on the principle of a capacitor where one plate of the capacitor stores charge and the other plate discharges it. The film capacitor’s capacitance value is determined by the distance between the plates, the size of the plates, and the dielectric constant of the film.
