Film capacitors, also known as film dielectric capacitors, are passive electrical components used in electronic circuits for filtering, coupling, tuning, and buffering to provide signal synchronization or AC voltage or current isolation, and to store electrical energy. The ECQ-V1H104JL2 is a variant of a film capacitor. This article explores the application field and working principle of the ECQ-V1H104JL2 capacitor.

Application field:

The ECQ-V1H104JL2 film capacitor is designed for filtering applications in AC circuits and is used for power factor correction, specifically reactive power compensation. It can improve the power factor of the entire system by reducing or eliminating the lagging power factor produced by inductive loads. It is particularly well suited for high-voltage applications, both in AC circuits and in DC circuits. Additionally, since the construction of metal aluminum film capacitors is superior to other capacitor types, they can perform well even in extreme temperatures and vibration.

Working Principle:

The ECQ-V1H104JL2 film capacitor operates on a simple principle. It consists of two aluminum metalized film electrodes rolled up onto a spool. The electrodes are positioned between a dielectric and two electrolyte-filled reservoirs, which are separated by a direct-current (DC) blocking material. The DC blocking material prevents DC current from passing through the capacitor, but allows AC current to pass freely. When an AC voltage is applied to the electrodes, the electrical field that is generated causes the metalized film electrodes to move relative to each other, causing a change in capacitance. This change in capacitance alters the AC voltage, which is either amplified (if capacitance increases) or attenuated (if capacitance decreases).

Conclusion:

The ECQ-V1H104JL2 film capacitor is a variant of a metal aluminum film capacitor and is most commonly used for power factor correction in AC circuits. Its construction is superior to other capacitor types and can withstand extreme temperatures and vibration. It operates on a simple principle involving two electrodes, a dielectric, and two electrolyte-filled reservoirs. When an AC voltage is applied to the electrodes, the electrical field that is generated causes the metalized film electrodes to move relative to each other, causing a change in capacitance, which alters the AC voltage. As the ECQ-V1H104JL2 is well suited for high-voltage applications in both AC and DC circuits, it is an ideal choice for filtering applications.
