The ECQ-E4393KFB is a type of film capacitor designed for a variety of applications, such as motor starting, power protection applications, and motor power control. It is a non-polarized, double-sided aluminum electrolytic capacitor with a capacitance rating of 4.7 μF and a voltage rating of 400 volts. The ECQ-E4393KFB is designed to offer excellent performance, reliability, and safety.The ECQ-E4393KFB features a low equivalent series resistance (ESR) which makes it suitable for power supply circuits and surge current applications. It also provides excellent high-frequency performance and high stability throughout its working temperature range. The ECQ-E4393KFB offers a wide range of operating temperature range (-40°C to +85°C) and an excellent shelf life of 10,000 hours. This makes the ECQ-E4393KFB the ideal solution for long-term projects and applications.

ECQ-E4393KFB Working Principle

The ECQ-E4393KFB works on the same principle as any other polarized capacitor. It has two metal plates, one of which is covered with an insulator. When a voltage is applied to the (electrically) isolated plate, a charge is stored in the capacitor’s dielectric material. As current flows through the capacitor, it builds up a charge on both plates. This stored electrical energy provides the capacitor with its ability to act as an energy storage device. The magnitude of the charge stored in the capacitor is determined by its capacitance rating, which is related to the amount of energy stored in the capacitor.

Conclusion

Film capacitors, such as the ECQ-E4393KFB, offer excellent performance and reliability. Their unique features, such as low ESR, high stability, temperature range, and long shelf life, make them ideal for a variety of applications. Furthermore, their working principle is the same as other polarized capacitors: the application of a voltage will create a charge that the capacitor can store for later use. Overall, the ECQ-E4393KFB is a great choice for applications that require excellent performance and reliability at extreme temperatures and humidity.
