Film Capacitors

Film capacitors are a type of capacitor that use thin plastics or other dielectric films as the dielectric material between their plates. Due to their stability, reliability, and high capacitance, these capacitors are widely used in a range of applications. One of the most popular types of film capacitors is the ECW-H20412HVB.

ECW-H20412HVB Application Field

The ECW-H20412HVB is a medium voltage film capacitor with a voltage rating of 4,160VAC. Due to its high dielectric strength and high capacitance, it is ideal for use in high performance power supplies, high voltage filters, switching power supplies, motor drives, electronic drives, lighting systems, and in high-frequency applications. It is also capable of handling a range of temperatures, making it an excellent choice for extreme temperature applications.

Working Principle of ECW-H20412HVB

The ECW-H20412HVB film capacitor consists of two plates, an anode and a cathode, which are separated by a dielectric material. When voltage is applied to these plates, a capacitance is formed which stores electrical energy. As the voltage across the capacitor increases, so does the capacitance. The electrical energy stored in the film capacitor is then released in the form of a current. This current is then used to power electrical devices.

In order to maintain high levels of stability and reliability, the ECW-H20412HVB film capacitor uses a range of materials, including a metalized polypropylene film as the dielectric material, and an acrylic adhesive for insulation. The capacitor also features a built-in safety device and a self-healing design which helps to protect the capacitor from damage when a fault occurs.

Conclusion

The ECW-H20412HVB film capacitor is a reliable, stable, and high capacitance capacitor which is capable of handling a wide range of temperatures. It is ideal for use in power supplies, electronic drives, and high-frequency applications. It is also capable of self-healing in the event of a fault, making it an excellent choice for extreme temperature applications.
