Film Capacitors

Film capacitors, also called plastic film capacitors, are manufactured by winding a plastic film around a metallic core. These capacitors are designed with either paper or plastic dielectric layers, and may vary in size depending on application. These capacitors can be used for a variety of applications, from power electronics to low-voltage, communication, and audio equipment.

Application Field and Working Principle

The ECQ-E2104JB is designed for a wide range of applications, including power electronics, low-voltage, and communication, and audio equipment. This capacitor is capable of providing stable and reliable electrical performance for up to 30,000 hours.

The ECQ-E2104JB film capacitor is equipped with a metal insulated polyester film dielectric that enables high-voltage operation and superior electrical properties. The metal-insulated dielectric can withstand temperatures up to 125°C and provides excellent insulation resistance. The capacitor is also capable of handling large ripple current values, high temperatures and high voltage.

The ECQ-E2104JB film capacitor is a non-electrolytic capacitor that works by using the principle of electrostatic storage. It stores electrical energy in the form of an electrostatic field between two set of metal plates. The metal-insulated dielectric layer acts as a barrier and prevents the electrical force between the two plates from dissipating.

The ECQ-E2104JB capacitor is also designed with a surge current capability, enabling it to easily handle high-voltage transient voltage events. The surge current capability is achieved by increasing the thickness of the metalinsulated dielectric layer, increasing the capacitance and increasing the peak current carrying capacity.

The ECQ-E2104JB’s long life expectancy and superior electrical properties make it an ideal choice for power electronics and low-voltage, communication and audio equipment. Its metal-insulated polyester film dielectric and surge current capability make it well suited for high-voltage applications in automotive and other applications.
