Film capacitors, also known as plastic film capacitors, are a type of capacitor that uses thin plastic film as its dielectric material and metallic film electrodes to store electrical energy. The ECW-F4105JL is a capacitor made specifically for high density applications such as mobile phone base stations and DDIC base station circuits. This article will look at the application field and working principle of the ECW-F4105JL film capacitor.

Application Field

The ECW-F4105JL film capacitor is a low profile radial lead capacitor that is designed for high density applications. It has a reduced height of only 2.0mm, which makes it well suited for mobile phone base stations, DDIC base station circuits, and other applications where space is limited. The ECW-F4105JL capacitor also features low self-heating, high capacitance stability, and low ESR. In addition, its non-polar design makes it ideal for DC-link applications.

Working Principle

The ECW-F4105JL is a non-polar film capacitor that utilizes thin plastic film as its dielectric material and metallic film electrodes to store electrical energy. It works on the principle of electrostatic energy storage, where an electric field is created between two metal plates separated by a thin dielectric material.

When an electric current is applied to the capacitor, the metal plates become charged and an electric field is formed between them. This electric field causes electrons to move from one plate to the other, thus creating a build up of charge. This charging process occurs until the capacitor reaches its maximum charge, and the stored energy can then be released when the capacitor is disconnected from the power source.

In addition to the plastic film used as a dielectric, the ECW-F4105JL also uses a combination of metal electrodes on the surface of the plastic film to store the electric charge. These electrodes are connected to the two terminals of the capacitor to create an electrical connection when the capacitor is connected to a power source.

The electric field that is created within the capacitor is what allows it to store the electrical energy. The ECW-F4105JL capacitor has a high capacitance value, which means that it is capable of storing a large amount of electrical energy despite its compact size.

Conclusion

The ECW-F4105JL film capacitor is designed for high density applications, such as mobile phone base stations, DDIC base station circuits, and other applications where space is limited. It works on the principle of electrostatic energy storage, where an electric field is created between two metal plates separated by a thin dielectric material. The ECW-F4105JL is a non-polar capacitor that has a high capacitance value and low self-heating. These characteristics make it perfect for DC-link applications.
