Working Principle

The working principle of a film capacitor is quite simple. It consists of two conductive plates that are separated by an insulating film. The current flow through the two conductive plates creates an electrostatic field between them, which is measured in farads. This electrostatic field is stored in the dielectric film, and can be discharged when the capacitor is connected in the circuit.

A wide range of dielectric materials are used to make film capacitors, such as polypropylene, polyester, Teflon, and polystyrene. MKP385320250JKI2B0 uses polypropylene as its dielectric material, which has a low loss factor and high breakdown voltage. Polypropylene is also widely used in motor runs and AC line filtering due to its superior temperature stability and high surge current capability.

The dielectric film of MKP385320250JKI2B0 is metallized, meaning that it is coated with a thin metal film. This metal coating provides an additional layer of insulation and improves the capacitor’s performance. The metallized film also ensures that the capacitor has a low dissipation factor, giving it high temperature stability and low noise operation.

Overall, MKP385320250JKI2B0 is a great choice for applications that require high voltage, high frequency performance, and other advanced characteristics. It is a highly reliable and durable film capacitor that can be used for a variety of applications. Its metallized film creates an additional layer of insulation, which helps to provide superior performance and long-term reliability.
