Film capacitors, also known as plastic film capacitors, plastic film dielectric capacitors, or film dielectric capacitors, are electrical components that use a plastic film as the dielectric material with metalized electrodes for both the anode and the cathode. They have become increasingly popular due to their low cost, lightweight construction, and wide range of voltage ratings. In this article, we will discuss the application field and working principle of the ECQ-E12102JE film capacitor.

Application Field

The ECQ-E12102JE film capacitor is intended to be used in wide range of applications such as switchers, amplifiers, low-noise audio systems, power supplies, and many industrial and consumer products. Some of the features that make it suitable for use in these applications include its low ESR, high dielectric withstanding voltage, and high ripple current capability.

Working Principle

The ECQ-E12102JE film capacitor operates on the basic principle of charging and discharging a dielectric medium, in this case, a plastic film. The metalized electrodes of the capacitor form part of a circuit. When the circuit is powered, an electrical charge is generated in the capacitor and this charge is stored in the dielectric medium. The electric field across the dielectric causes the charge to remain in the medium even after the power has been removed. When the circuit is again powered, the capacitor stores this charge again for subsequent use.

The film capacitor has a very small internal resistance, or ESR, and so it\'s able to both store and discharge its charge very quickly. It also has a high dielectric withstanding voltage and is able to withstand sudden voltage spikes, making it suitable for use in high voltage applications. Moreover, it offers high ripple current capability, meaning it can efficiently reduce disturbances in power supply systems.

Conclusion

The ECQ-E12102JE film capacitor is a versatile electrical component used in a wide range of applications. It\'s lightweight and low cost design make it highly attractive for many companies. The capacitor has a low ESR, high dielectric withstanding voltage, and high ripple current capability, making it suitable for use in applications such as switchers, amplifiers, low-noise audio systems, and power supplies.
