Film Capacitors

MKP385351125JC02R0 application field and working principle

Film capacitors, also called polyester/polypropylene capacitors, are electronic components used in the circuit boards of a variety of electronic devices and consumer appliances. The aim of using these capacitors is to provide a smooth junction between the components of the circuit board and offer improved energy storage capability for applications such as high frequency spark gap arc gaps, current blocking, DC-DC noise reduction in communication and low-voltage AC circuits.

The MKP385351125JC02R0 is one of the most popular types of film capacitors. It has a rated voltage of 500V, a rated capacity of 5μF and a dielectric of polypropylene type. This type of capacitors is ideal for use in high pulse or low frequency applications, as it provides improved energy storage efficiency and capacitance stability over a wide temperature range (from -30°C to +125°C).

The working principle of a film capacitor is based on the dielectric medium, which is a thin film of polymer material. This film acts as an insulator between the two conductive plates that are usually made of aluminium, copper or steel. When the plates of the capacitor are exposed to an electric field, the dielectric material gets polarized, allowing for electrons to flow between the plates. This in turn creates an electric charge, which is responsible for the storage of the energy.

MKP385351125JC02R0 film capacitors are usually used in automotive, lighting, broadcast & audio, motor control and power supplies applications. Additionally, they are well-suited for use in DC-DC converters, high-frequency spark gap arcs, and low-voltage AC circuits. Due to their excellent energy storage capability, they offer a significant level of energy efficiency when compared to other types of capacitors. They are also highly reliable in terms of reliability, leakage current and service life.

In conclusion, MKP385351125JC02R0 film capacitors are ideal for use in a wide range of applications, particularly in high frequency or low frequency applications. They offer excellent energy storage capability and are highly reliable. When used in the correct manner, these capacitors can significantly improve the performance of a variety of electronic devices and consumer appliances.
