Film capacitors are passive components that store electric charge in an electric field, and are typically made up of a film isolated between two plates which are connected to a terminal, most often a metallic foil. Sometimes, an air gap between the plates is necessary to increase dielectric strength and potential wear resistance of the capacitor. The film capacitors are preferred over other capacitors in many applications, due to their excellent electrical properties, high volumetric efficiency, robustness and long life.

ECW-HA3C202HQ is a film capacitor of the High Voltage Series, with a rated voltage of 400V and a capacitance of 2.2μF. The capacitor terminals are made from aluminium. ECW-HA3C202HQ is manufactured by the leading capacitor manufacturer Elna Capacitors.

ECW-HA3C202HQ has wide range of applications, such as reducing EMI, improving power supply filtering, cabinet power supplies, quenching circuits, motor control and lighting. High voltage film capacitors could also be used in power factor correction, power system stabilisation and voltage smoothing. Its applications also include single-phase and three-phase power supplies, electrical appliances and DC power supplies.

The working principle of ECW-HA3C202HQ is just like other film capacitors. Whenever a voltage is applied across the two plates, electrons are attracted to the positive plate and released from the negative plate. This creates a potential difference between the two plates, which creates an electric field that stores energy. As the capacitor’s plates become more charged, the voltage increases in the electric field and the capacitance increases. When the voltage is removed, the capacitance decreases.

ECW-HA3C202HQ is the perfect choice for your applications requiring high voltage capacitors, with its excellent electrical properties, robustness and long life. Its wide range of applications and working principle make it ideal for a variety of applications that require a reliable, high quality power supply capacitor.
