Film capacitors are a type of capacitor which is widely used in various types of electronic applications due to their generally superior performance as compared to other dielectric materials and their associated capacitors. This article will discuss the application field and working principle of the MKP385522025JIM2T0 film capacitor.

Introduction

The MKP385522025JIM2T0 film capacitor (also known as a polyester film capacitor) is a type of capacitor which utilizes a dielectric material made of polyester film. This type of capacitor has a number of advantages over other types of capacitors, such as higher volumetric efficiency (space saving), high dielectric strength, low values of dielectric losses due to its low dissipation factor, and stability of capacitance over applied voltage and frequency.

Application Field

Due to the high performance of the MKP385522025JIM2T0 film capacitor, they are primarily used in high frequency applications, such as switched-mode power supplies, inverters, motor drives, and high frequency filters. As they offer superior performance compared to other dielectric materials and their associated capacitors, they are often preferred for applications requiring higher frequency response, higher temperature corrosion resistance, and higher dielectric strength.

Working Principle

The MKP385522025JIM2T0 film capacitor utilizes the general working principle of a capacitor, whereby two conductors are separated by an insulating material, usually a dielectric. The electrodes consist of two metal plates which are separated by an insulating material, in this case a polyester film. The plate separation determines the capacitance, while the area and quality of the dielectric will determine the dielectric loss, breakdown voltage, and the temperature rating of the capacitor. When a voltage is applied to the capacitor, the metal plates become charged and an electric field is formed due to the charged cellular structure of the polyester film. This electric field allows for an easy passage of current and energy from one plate to the other.

Conclusion

The MKP385522025JIM2T0 film capacitor is a well-suited for a variety of applications, due to its superior performance as compared to other dielectric materials and their associated capacitors. This type of capacitor is primarily used in high frequency applications, such as switched-mode power supplies, inverters, motor drives, and high frequency filters. The working principle relies on the separation of two metal plates by a dielectric, in this case a polyester film, which allows for an easy passage of current and energy from one plate to the other.
