It has stable parameters and excellent performance to filter EMI. With its high-stability and low parasitic parameters, ECW-H20222JV is capable to accurately regulate DC/AC circuits.

Working Principle

The working principle of ECW-H20222JV is based on the capacitance value, which relies on the geometry of the metallized polyester film electrodes and the distance between them. This type of capacitor is constructed of two metallized sections, which form the plates, and the polyester film as the dielectric medium. The size and capacitance of ECW-H20222JV depends on two factors: the thickness of the film and the distance between electrodes (plastic film capacitors).

The capacitance of ECW-H20222JV is determined by the equation C = Ε* S/d. Here Ε is the dielectric constant of film, S is the area of the capacitor\'s plates and d is the distance between them. The internal resistance will affect the performance of capacitor in AC circuits. ECW-H20222JV has low resistance which is beneficial in AC application.

The leakage current of the ECW-H20222JV is affected by the charge reaction of the film material and the fungal deterioration film due to humidity. Therefore, ECW-H20222JV capacitors should be sealed in airtight containers with low moisture content.

Conclusion

In summary, ECW-H20222JV is a specialized film capacitor which is widely used in many applications due to its excellent performance and features. It has stable parameters, high reliability and low resistance, making it ideal for power factor correction and noise suppression.Understanding the application fields and working principle of ECW-H20222JV will help engineers in selecting the best capacitor for their applications.
