Film Capacitors

MKP385215125JC02W0 Application Field and Working Principle

Film capacitors are a type of capacitor that utilizes metalized plastic films as dielectric material to obtain capacitance. Over the past decade, the popularity of film capacitors has grown significantly, largely due to its small size, reliable performance, and ability to withstand high frequency and ripple voltage. The MKP385215125JC02W0 metalized polypropylene film capacitor can be used in various applications.

Application Field

MKP385215125JC02W0 metalized polypropylene film capacitor has wide application in various industries, such as switched mode power supplies, lighting control system, x-ray machines, medical equipment, ATM machines, medical instruments, automatic measuring devices, high frequency welding machines, radio communication equipments, home appliance equipment, wind power generation voltage and frequency regulation, vacuum equipment, and plasma cutting machine.

Working Principle

The working principle of a film capacitor is the same as other capacitors, with the movable plate and static plate. In a negative-electrode film capacitor, the positive electrode plate is made of conducting metal film, and is applied with an oven-dried oxide film, which will not be corroded by moisture. The negative pole electrode plate is made of metal film with special coating or oxide film, and its structure is arranged in a layered manner to ensure the existence of multiple overlapping dipole structures Thereby, the electric field distribution will be uniform and the leakage current will be small, so as to reach the ultimate high dielectric property.

Conclusion

The MKP385215125JC02W0 metalized polypropylene film capacitor can be used in various applications to regulate frequency and voltage. The working principle is the same as other capacitor. It has a positive electrode plate that is made of conducting metal film and a negative pole electrode plate are made of metal film with special coating or oxide film. The multiple overlapping dipole structures ensure uniform electric field distribution and small leakage current, thus obtaining ultimate high dielectric properties.
