Film capacitors are passive electrical components that are used in countless electronic circuits for numerous reasons. The particular purpose and function of a film capacitor depends on the structure of the film used. The ECQ-E2103KS is a type of film capacitor that can be employed for many different purposes. This article will outline the application field and working principle of this particular variety.

Application Field

Utilizing a high-grade polycarbonate film as the dielectric, the ECQ-E2103KS is designed to be used in low-voltage DC power supplies, network interfaces, and AC power supplies. It can also act as a decoupling capacitor in the output of DC/DC converters, as a polarity protection in AC/DC converters, and as a coupling capacitor for switching power supplies. In addition, the ECQ-E2103KS is an excellent choice for DC blocking, AC rectification, and electrical isolation.

Working Principle

A film capacitor\'s construction is based on dielectric material, often referred to as film, between two electrodes. This dielectric material is separated from the two electrodes by a polyester film that serves to keep the two sides of the capacitor from coming into contact with each other. As electrical current is passed through these layers, a nano-layer of electric charge is built up on the porous layers. This layer of electric charge acts as a barrier, allowing for the capacitor to store energy. The difference between the amount of charge that is stored on each side of the capacitor is what causes the capacitor to have a storage capacity.

The ECQ-E2103KS is designed to have a low equivalent series resistance, meaning it will have less internal power loss and a self-healing nature.The self-healing nature of this variety of capacitor is due to a layer of polycarbonate film being able to inflate and deflate with the charge and release the energy. This layer is designed to be as thin as possible while still providing an effective dielectric layer.

The range of capacitance that the ECQ-E2103KS offers makes it the perfect choice for virtually any type of application. The low equivalent series resistance ensures that it can handle large amounts of power with little to no power loss, while the self-healing property allows for increased durability over other capacitor types. With these properties, along with its reasonable pricing, the ECQ-E2103KS can be found in countless electronic circuits across the world.

Conclusion

The ECQ-E2103KS is a film capacitor that can be employed in low-voltage DC power supplies, network interfaces, and AC power supplies. Its high-grade polycarbonate film dielectric is designed to ensure a low equivalent series resistance and self-healing property. The low cost and wide range of capacitance makes the ECQ-E2103KS an attractive option for circuit designers.
