Working Principle of ECQ-E4393KZ Film Capacitors

A film capacitor consists of an insulating film between two electrodes. The insulating film can be made from materials such as polyester, polypropylene, Teflon or others. The film has the property of blocking direct current and allowing alternating current to flow.In the case of the ECQ-E4393KZ, the insulating film is made from a metalized polyester sitting in an aluminum can. The metalized layer on either side of the film acts as the capacitance plates, one positive and one negative. When an AC voltage is applied across the two plates, an electric field forms between them, allowing the current to flow freely.When the AC voltage is removed, the electric field collapses, blocking the current flow until the AC voltage is applied again. This is the process by which an ECQ-E4393KZ film capacitor works, storing and releasing energy each time the AC voltage is applied.

Conclusion

The ECQ-E4393KZ film capacitor is a highly popular and versatile film capacitor. It is used in a wide variety of applications, from consumer electronics to power supplies and motor drives. The ECQ-E4393KZ has a rated voltage of 4 to 400Vdc and a capacitance range of 0.022uf to 0.01uf. The capacitor’s working principle is based on the creation of an electric field between two metalized plates. The ECQ-E4393KZ film capacitor is an efficient and reliable component with a long life of up to 5,000 hours at 85°C and low ESR and ESL.
