ECQ-E10124JFB

Film capacitors are traditionally constructed with a dielectric layer of uncalendered or calendered film, most commonly polypropylene (PP) or polyester (PET). Metallized films involve the deposition of a thin layer of metal, such as aluminum or zinc, onto the surface of the dielectric film. The addition of this conductive element alters the capacitance and behavior of the capacitor. In the case of shunt capacitors, film capacitors are equipped with an internal resistance enabling the device to act as a short circuit between two points in a circuit.

The ECQ-E10124JFB application field and working principle focuses on metallized polymer film capacitors. It is widely used in power electronics, for example, in DC link, AC power bypass, snubber, and AC filter applications. The ECQ-E10124JFB capacitor utilizes a metallized polypropylene film construction for stability and excellent high frequency characteristics. The device utilizes a unique construction which combines the advantages of metal electrodeposition and film coating techniques. This includes a higher level of surge current capacitance and stability, as well as improved AC withstand. The metallized construction also offers a very low termination resistance and low bulk capacitor losses.

The way in which the ECQ-E10124JFB functions is essentially a process of electrical charge storage. A capacitor is made of two metal plates separated by a dielectric. When a voltage is applied to the plates, it creates an electric field across the dielectric. The electric field causes a buildup of electrical charge on the plates. When the voltage is removed, the electric field is removed and the stored charge is released back into the circuit.

The ECQ-E10124JFB is designed for use in a wide variety of applications including, but not limited to, DC link, AC power bypass, snubber, and AC filter capacitor applications. It features excellent high temperature, thermal and electrical performance. Its low loss makes it well suited for DC link, AC power bypass, snubber, and AC filter applications. The capacitances can range from 0.22µF up to 3.3µF. Additionally, the ECQ-E10124JFB can operate up to 2kVAC and can handle voltage ripple up to 50V.

In conclusion, the ECQ-E10124JFB is a metallized polypropylene film capacitor designed for use in a variety of applications. The metallized construction ensures a low termination resistance and low bulk capacitor losses, while the unique construction combines the advantages of metal electrodeposition and film coating techniques to offer high surge current capacitance and stability, as well as improved AC withstand. The ECQ-E10124JFB is capable of reaching ±2kVAC and can handle voltage ripple up to 50V.
