Film capacitors, also known as film dielectric capacitors, are energy storage components that store electrical energy in an electric field created between a dielectric film and a metal on either side of the film. ECW-H12202HV is one of the dielectric film capacitors. This article will explore its application field and working principle.

Application Field

The ECW-H12202HV capacitor has a wide range of applications. It can be used in the printed circuit boards (PCBs) for high voltage access. It is also used in many audio-frequency applications, such as amplifiers, speakers and subwoofers. It is suitable for high DF (dissipation factors) applications and is often used in HVAC circuits, stepper motor drivers and high frequency switching power supplies.

Working Principle

ECW-H12202HV capacitor consists of two metal plates and a dielectric film placed between them. When an electric current is applied, it creates an electric field that stores energy as an electrostatic charge in the capacitor. The dielectric film acts as the insulating medium and no current passes through it. However, as the electric current increases, the dielectric strength of the film also increases. As a result, the insulating effect of the film allows the capacitor to store more energy. The amount of energy stored depends on the size of the electric field, the thickness and dielectric constant of the film, as well as the area of the plates.

Conclusion

ECW-H12202HV capacitors are widely used in various applications such as audio-frequency applications, HVAC circuits, stepper motor drivers and high frequency switching power supplies. It stores energy as an electrostatic charge in an electric field created between a dielectric film and metal plates. The amount of energy stored depends on the size of the electric field, the thickness and dielectric constant of the film, as well as the area of the plates.
