ECW-H20112RJV

Film capacitors, also known as plastic film capacitors, are capacitors that use a film as a dielectric material. The ECW-H20112RJV capacitor is a type of film capacitor and is used in a variety of applications. This article will look at the application field and working principle of the ECW-H20112RJV film capacitor.

Applications

The ECW-H20112RJV film capacitor is a high voltage, polypropylene dielectric capacitor, with a rated capacitance of 4.7uF, and is designed for applications needing high volatge ratings of 400V-1200V. It is particularly useful for power supplies, and for industrial electronics, such as frequency inverters, HVAC, ballasts, UPS, and PFC controllers. It is also useful for HID lighting applications, such as street lights.

Working Principle

The basic working principle of the ECW-H20112RJV film capacitor is similar to that of other types of capacitors. It consists of two metal plates separated by a dielectric material, which in this case is a film of polypropylene. When a voltage is applied across the plates, one plate becomes charged positively and the other negatively, thus creating an electric field between them. This electric field stores energy until the voltage across the capacitor plates drops.

The dielectric material used in the ECW-H20112RJV film capacitor has unique properties that make it highly suitable for high voltage applications. The polypropylene film has high frequency dielectric strength, which means it can withstand high voltages without breakdown or degradation. It has excellent self-healing properties, meaning it can recover from short circuits that occur due to high voltages, providing improved reliability in power supply applications.

The ECW-H20112RJV film capacitor also has a high insulation resistance and low dissipation factor, which makes it ideal for high frequency applications. It offers superior temperature stability and a long lifetime, making it well-suited for industrial applications. Additionally, its shielded construction reduces interference from other components in the circuit.

Conclusion

The ECW-H20112RJV film capacitor is a high voltage capacitor with a rated capacitance of 4.7uF, and is designed for use in high voltage applications. It has excellent dielectric strength, self-healing properties, and temperature stability, making it ideal for applications such as power supplies, HID lighting, frequency inverters, and HVAC.
