ECW-FD2J564K Film Capacitors – Application Field and Working Principle

Film capacitors comprise mainly of two thinner metal foil plates, kept in the \'leaky\', rather conductive dielectric material, between them.

The basic principle of the operation of capacitors is that when voltage is applied to between the two plates, a charge is held, which is formed by the pattern of electrical charges on the plates.

The application of the ECW-FD2J564K film capacitor is part of a form of dielectric capacitance, namely polyester film and metallized polyester film type.

These are multipurpose devices that can be used in many fields, including electrical and electronic equipment, AC mains household appliances and automobiles, telecommunications and computers.

How it works?

When the two plates are connected to AC voltage source, a signal is applied across them. The signal is then transmitted through the dielectric material, which acts as an energy storage.

As a result, the positive and negative charges on the two plates attract each other and a charge held on the plates is created. This charging and discharging process is called the capacitor effect.

This capacitor effect is used for static electricity or DC blocking, or for creating a time delay. The ECW-FD2J564K film capacitor is also used for coupling between the stages of a system and to suppress electrical noise.

Advantages

The ECW-FD2J564K film capacitor is known for its good frequency characteristics, low loss, and good temperature stability.

A large capacitance value can be obtained from a small space, and film capacitors also offer excellent insulation resistance and self-healing capabilities. In addition, they can be availed in large capacitance values, low dissipation factors and small temperature coefficient.

In terms of construction, they are lightweight, thin, and small compared to other capacitors. This makes them very attractive for product designers, as they are convenient for incorporation into existing spaces in products, and can be placed in tight spaces due to their small form factor.

Applications

The ECW-FD2J564K film capacitor has seen successful usage in a myriad of applications that require the high-quality dielectric properties it offers. It is used in the manufacturing of electronic and electrical products, mains household appliances, computers and telecommunications.

The ECW-FD2J564K is also used as a blocking capacitor in power supplies, and other applications that require uniform excitation and input. This device is also used to store energy and act as charge pump capacitor.

In a power saving design context, the low loss characteristics of the ECW-FD2J564K make it suitable for use in stand-by power supplies. It is also used for bypassing, coupling, and DC blocking, as well as for voltage surge protection.

Conclusion

The ECW-FD2J564K film capacitor is widely used for many useful applications. This is due to its specifications that include high dielectric characteristics, low loss and good temperature stability, as well as its strong capacitance characteristics.

The space effective construction of the ECW-FD2J564K and its low dissipation and low thermal coefficient also make it a great choice in designs where space and weight are of a premium.
