Film Capacitors

The ECQ-E2W155KC is a type of film capacitor, which is a type of capacitor used in a wide range of applications. It is a passive two-terminal electrical component designed to store and release electrical energy. Film capacitors are non-polarized devices and are usually made from electrical grade plastic film and metal foil. The ECQ-E2W155KC is a product made by Panasonic, and it is a surface mount, multilayer capacitor of small profile size and highly flexible characteristics.

Application Field

Film capacitors are used in a wide range of applications, such as electronics, filtering, snubbing, EMI suppression, or bypass components. The ECQ-E2W155KC is used mainly for consumer electronics equipment, which demands utmost quality and durability. These products are used in products such as audio systems, camcorders, TVs, game consoles, and other types of electronic equipment. They are also used in switch mode power supplies, automotive, and telecommunication applications.

Working Principle

The working principle of film capacitors is based on the electrical fields between two conductors. They achieve their capacitance through the electrical fields established between the two conducting plates formed on the thin insulating layer between them. The capacitance of a film capacitor is proportional to the surface area of the conductors, the gap between them, and the dielectric constant of the insulating layer. The ECQ-E2W155KC is a multilayer capacitor, meaning it consists of multiple layers of metallized film and insulating material. Each layer is composed of two metalized films which form two electrodes and an insulating film which forms the dielectric. The dielectric’s role is crucial, since its capacitance is proportional to its dielectric constant.When a voltage is applied to the device, an electric field is established between the two plates of the device. The plates are connected by a dielectric material which acts as a medium through which the charge can flow and release energy. This electric field allows the device to store or release energy as current is applied or removed.

Conclusion

The ECQ-E2W155KC is a type of film capacitor used mainly for consumer electronics applications. Its working principle is based on the electrical fields between two conductors established between the two conducting plates of the capacitors. It is composed of multiple layers of metallized film and insulating material which act as electrodes and the dielectric, respectively. The capacitance of the device is proportional to the surface area of the equipment, the gap between the conductors, and the dielectric constant of the insulating layer.
