Film Capacitors

A film capacitor, or plastic film capacitor, is a capacitor that consists of a thin plastic film placed between two metal plates and rolled together in a compact way. The plastic film works to provide electrical insulation and capacitance between the two metallic plates, contributing to the capacitors ultimately performance. Film capacitors usually come stacked in different configurations, allowing them to be used in many different applications, such as audio frequency filtering, energy storage, and pulse discharge filtration.

MKP385539063JPI2T0 application field and working principle

The MKP385539063JPI2T0 is a special type of film capacitor designed to work in a broad range of applications. Its main feature is that it has an exceptionally wide temperature range, making it suitable for both low-temperature and high-temperature environments. It is often used for energy storage, coupling, snubbing, bypass, and delay applications. The MKP385539063JPI2T0 is made from two metalized polypropylene (PP) films wound together. The metalizing process adds a layer of ultra-thin aluminum onto the PP film, greatly increasing the capacitance and reducing the ESR. This increase in capacitance also helps reduce the signal loss when the MKP385539063JPI2T0 is used for high frequencies.

The working principle of the MKP385539063JPI2T0 is based on the principles of capacitance. In the film capacitor, the electric field is build up the two metalized PP films rolling together, each roll containing one metalized PP film and one dielectric PP film. As the capacitor is charged, electrical charge accumulates on one film while the other one is electrostatically discharged, resulting in capacitance. The dielectric properties of the PP film allow for a low dielectric absorption ratio and a low dissipation factor, while the metalizing increases the capacitance and reduces the ESR.

The MKP385539063JPI2T0 has a number of advantages over other types of capacitors. For instance, its wide temperature range makes it suitable for various applications. Additionally, its low ESR improves the charging and discharging times, while a low dissipation factor ensures greater efficiency. Its small size and slim design provide a large capacity within a compact package as well.

In conclusion, the MKP385539063JPI2T0 is a special type of film capacitor with a wide range of applications, from energy storage to audio frequency filtering. Its metalized PP films provide excellent capacitance and low ESR performance while its wide temperature range and small size make it suitable for various applications.
