Working Principle
The working principle of the ECW-H8202HL is based on the electrostatic interaction between the positive and negative electrodes. When a voltage is applied to the two electrodes, an electric field will be established between them, causing electrons to move from one side to the other. As electrons move, they will be attracted to the oppositely charged electrodes, causing a current to flow through the capacitor. This phenomenon of opposite charges attracting one another is known as “capacitance”.

The electric field between the two electrodes creates a density of charge in the dielectric material, known as a “dielectric polarization”, which results in a capacitance. The capacitance depends on the size of the electrodes, the distance between them, and the type and thickness of the dielectric material. The ECW-H8202HL uses a metallized polyester film as its dielectric, which helps to provide a high level of stability and reliability in the capacitor.

Conclusion
In conclusion, the ECW-H8202HL is a high-precision metallized polyester film capacitor with an aluminium can housing and a dielectric that provides excellent stability and reliability. Its low D.F and high performance make it ideal for applications such as motor control, power supply & conversion, lighting, instrumentation, and signal conditioning. Its working principle is based on the electrostatic interaction between the two electrodes, the size of the electrodes, distance between them, and the type and thickness of the dielectric material. This makes the ECW-H8202HL particularly suitable for high-frequency and power applications.
