Film capacitors are a type of capacitor that stores energy in an internal dielectric film. Among many other types of capacitors, they are known for having very low leakage current and low parasitics that make them useful in a wide variety of applications, such as high frequency switching circuits and power supplies. The MKP385527125JPP4T0 is a good example of a film capacitor and in this article, we will cover its application fields and working principle.

Application Field

The MKP385527125JPP4T0 is a bias-corrector film capacitor, which means that it has a built-in application circuit. This circuit helps to control the voltage at which the capacitor is operating. As such, this capacitor is very resistant to voltage changes and is suitable for use in a wide range of applications.

MKP385527125JPP4T0 is a radial, non-inductively wound, polyester-based capacitor. It is used in DC motors, DC choppers, SMPS converters, HIFI systems, audio-amplifiers, etc. It is also commonly used in the automotive industry as it provides a reliable power source to various automotive systems.

In addition, this film capacitor is resistant to external electrical noise, making it suitable for use in power conditioning applications where power quality is of utmost importance. It is also widely used in lighting systems and in energy saving lamps, as its ability to withstand high temperatures up to 105°C and low-temperature cold start capabilities make it an ideal choice.

Working Principle

The MKP385527125JPP4T0 is a polyester-based film capacitor, which means that it contains a thin layer of polymer sandwiched between two metal electrodes. This polymer dielectric film has two layers, with the outer layer having holes that allow electrons to jump from one layer to the other. This creates a rectifying effect between the two layers which helps to store the energy.

In addition, the film is also designed to minimize the self-inductance of the capacitor. This is done by winding the film in a particular way in order to create an effective shielding effect. This helps to ensure that the capacitor is very stable under high frequency vibrations, and reduces the possibility of damage caused by high-frequency radiation.

The primary advantage of the MKP385527125JPP4T0 film capacitor is its very low ESR, or equivalent series resistance. This makes the capacitor very efficient in terms of energy storage and power supply, as well as highly reliable in the long run. In addition, this capacitor can be used in a wide temperature range, from -40°C to 105°C, making it suitable for a variety of operating environments.

In summary, the MKP385527125JPP4T0 is a polyester-based film capacitor that is suitable for a wide range of applications. It has a built-in application circuit that helps to maintain the capacitor’s voltage and a very low ESR that makes it an efficient source of energy. Additionally, this capacitor is highly resistant to external noise and can withstand operating temperatures of -40°C to 105°C.
