MKP385356040JFI2B0

Film Capacitors

Film capacitors are one of the most popular types of capacitor due to their high reliability, long lifetime, low leakage current, and very short lead time. They are used in a variety of applications, including power systems, RF (radio frequency) communications, motor drives, high-voltage switching, and more. The MKP385356040JFI2B0 is a film capacitor designed for use in automotive and industrial applications.

Application Field

The MKP385356040JFI2B0 is a general-purpose film capacitor that can be used in a wide range of automotive and industrial applications. It is designed for use in a circuit as a low-frequency decoupling capacitor, voltage multiplier capacitor, as well as for filtering noise, ripple, and other high-frequency signals. It has an operating temperature range of -40°C to +120°C, a capacitance range of 0.22uF to 9.0uF, and a rated voltage of 25Vdc.

It can be used to improve the reliability of high-voltage power supplies and DC/DC converters by providing electrical noise and ripple filtering. It can also be used in applications such as automotive headlights, power inverters, fuel injection systems, airbag inflators, electric windows, windshield wiper motors, and electric vehicle power systems.

Working Principle

A film capacitor consists of two conductive metal plates separated by a dielectric material. When a voltage is applied to the capacitor, electrons accumulate on one of the plates while a charge of an opposite polarity is attracted to the other plate, thus creating a potential difference between the two. When the applied voltage is removed, the potential difference is dissipated.

The MKP385356040JFI2B0 is a polypropylene-film capacitor with siliconized sleeves that are designed to reduce contact resistance and inductance. These film capacitors provide superior performance over traditional electrolytic capacitors in terms of transient response, voltage stability, noise rejection, and overall reliability.

As a combination of low ESR, high capacitance, and a wide operating temperature range, the MKP385356040JFI2B0 is an ideal choice for many automotive and industrial applications. With its small size and low cost, it is quickly becoming one of the most popular film capacitors on the market.
