Film capacitors are a type of energy storage element that is commonly used in electronic systems, from consumer electronics to industrial control applications. ECQ-E2155KS is an advanced film capacitor that offers superior performance in a variety of applications. This paper will discuss the application field and working principle of the ECQ-E2155KS.

The ECQ-E2155KS is mainly used as an electrolytic capacitor in electronic circuits, where its combination of high voltage, low leakage current, and low cost make it ideal for applications where long life and high reliability are required. In addition to being used as an electrolytic capacitor, the ECQ-E2155KS is also used as a general-purpose filter capacitor, providing good performance in DC-DC power supplies and other power conversion applications. The ECQ-E2155KS is also widely used as a snubber capacitor, where its high capacitance and low equivalent series resistance (ESR) make it an effective means of suppressing voltage spikes in sensitive circuits.

The ECQ-E2155KS is a polyester film type capacitor that is available in a wide range of capacitance values from 33µF to 470µF. The maximum voltage rating for the ECQ-E2155KS is 50V. The operating temperature range for the ECQ-E2155KS is -40°C to +85°C. The insulation resistance (IR) for the ECQ-E2155KS is greater than 10,000MΩ. The leakage current for the ECQ-E2155KS is less than 0.05CV (uA) where C is the capacitance (µF) and V is the voltage rating (V).

The working principle of the ECQ-E2155KS is similar to that of other film capacitors. When the capacitor is placed in a circuit, an AC voltage is applied to the two terminals of the capacitor. This causes electrical charges to be stored on the two metallic layers of the capacitor, which act as the two "plates" of the capacitor. The electrical charge stored on the two plates creates an electric field between the two plates, which attracts and repels electrons. This store of electrical energy forms a parallel-plate capacitor, which is capable of storing electrical energy even when the AC voltage is removed from the circuit.

The ECQ-E2155KS offers excellent performance in a variety of applications requiring high-performance electrolytic capacitors, such as DC-DC power supplies, snubber capacitors, and general-purpose filter capacitors. The combination of high voltage, low leakage current, and low cost make the ECQ-E2155KS an ideal choice for applications where long life and high reliability are desired.
