Introduction

Film capacitors come in many shapes and sizes, each designed to accommodate a particular application. One of the popular capacitors is the MKP385420040JI20W0. This capacitor is rectangular in shape and has two terminals. It is designed to work in temperatures up to 105 degrees Celsius.

Application Field of MKP385420040JI20W0

The MKP385420040JI20W0 is usually used in power supplies. The capacitor is used as a filter capacitor or energy storage in the power supply circuit, which is used to convert alternating current to constant current and maintain its stability, thus providing a stable current for the circuit.

In addition to power supplies, the MKP385420040JI20W0 can also be used in high-reliability products. The capacitor is suitable for using in devices or equipment which require higher reliability and long-term stability. Its high temperature resistance allows it to work reliably even in hot environments.

Working Principle of MKP385420040JI20W0

The MKP385420040JI20W0 is an electrolytic capacitor. It consists of two conducting tubes filled with electrolyte. Between them is a thin layer of metal oxide (typically aluminum) that serves as the dielectric. When an electric field is applied, the electrolyte ions move to the surface of the dielectric, thus forming a conductive path between the two conducting tubes.

When a voltage difference is applied to the two terminals of the capacitor, the electric field builds up on the surface of the dielectric layer, which causes the electrolyte ions to move to the surface of the dielectric. This movement of ions forms a mobile electric field between the two conducting tubes, which stores energy. The electric field allows current to flow through the capacitor and allows electrical charge to be stored in the capacitor.

Conclusion

The MKP385420040JI20W0 is a popular film capacitor widely used for power supply applications and high-reliability products. It is designed with two conducting tubes and a thin dielectric layer. When a voltage is applied across the two terminals, an electric field builds up on the surface of the dielectric which causes current to flow through the capacitor and charge to be stored in the capacitor. It is important to note that this capacitor is designed for use in temperatures up to 105 degrees Celsius.
