Introduction

The MKP383362250JKM2T0 is a general-purpose film capacitor from the MKT/MKP series from Murata. It is a film-filled metallized polypropylene capacitor that is designed for high-voltage applications. This capacitor offers excellent dielectric properties, excellent stability, low ESR, and low losses. It is also known for its superior performance in high-frequency circuit applications.

Application Fields

The MKP383362250JKM2T0 capacitor is typically used in power electronics, AC/DC conversion, power factor correction, filtering, snubbers and other high-voltage types of applications. Its high-voltage rating of 1400V DC makes it ideal for applications in which high-voltage conditions need to be handled. Its wide-rated frequency range from 400 Hz to 50 kHz further expands its potential application areas. It is also suitable for use in high-temperature applications in the range of −40 °C to +85 °C. Its 95% efficiency makes it suitable for high-efficiency applications such as motor control and solar energy applications.

Working Principle

The MKP383362250JKM2T0 is a film capacitor, which uses two metal-film electrodes, placed in a dielectric material such as polypropylene or polystyrene, and separated by an insulating foil, to form a capacitor. The metal-film layers serve as the capacitor’s electrodes, and the insulating film serves as the dielectric. When a voltage is applied, the insulating film begins to tear apart (in essence, a very small gap) due to the electric field produced by the voltage. This process creates an electric field of opposite polarity, causing a charge build-up on the electrodes. This charge is counteracted by the opposing polarity, and the capacitance is determined by the amount of charge stored in the capacitor (i.e. the electric field).

Conclusion

The MKP383362250JKM2T0 is a film capacitor from Murata’s MKT/MKP series. It is designed for high-voltage applications and its rated voltage of 1400V DC and frequency range of 400 Hz to 50 kHz make it suitable for a wide range of applications. It is often used in power electronics, AC/DC conversion, power factor correction, filtering, snubbers and other high-voltage devices. The working principle of the device is based on the use of two electrodes that are placed in an insulating film. When a voltage is applied, the device creates an electric field of opposite polarity, resulting in charge build-up and the capacitance is determined by the amount of charge stored in the capacitor.
