Film capacitors, also known as plastic film capacitors or film dielectric capacitors, contain electrodes that are separated by a thin plastic film as the dielectric. In electronics, film capacitors are widely used as hidden as well as visible components both in the civil and industrial sectors due to their highly stable performance, low cost, and high frequency response. The ECQ-E1393KF is a film capacitor model, and its application field and working principle are described below.

Application Field

ECQ-E1393KF film capacitors are mainly used in AC power line filters, power supplies, and some other circuits, such as RC snubber networks and frequency-dividing circuits and direct current blocking capacitors. More specifically, they can be used to filter out high frequency noise in a power supply circuit, minimize harmonics while improving power factor and reducing power consumption, as well as reduce the bounce in solenoid operation. They are also suitable for high frequency coupling, high frequency bypass, and decoupling, DC blocking, and smoothing applications.

Working Principle

Film capacitors are based on the basic principle of capacitance, which states that the total capacitance that exists between two electrodes is determined by the area of overlap between them and the type of dielectric material used to separate them. In the case of the ECQ-E1393KF, the dielectric material is a thin plastic film, which serves to increase the surface area of the conductive electrodes. In addition to a higher capacitance value, the use of plastic film also provides a stable electrical performance over a wide range of conditions, including temperature, frequency, and voltage.

ECQ-E1393KF film capacitors use a structure known as a ‘Divided Plate Electrode’, which features a ‘flexible’ inner electrode whose shape is determined by a steel outer frame. The inner electrodes are formed in such a way that they divide the plastic film into two distinct dielectric layers which serve to separate the two conductive surfaces. The electrical field created between the two layers of the film acts to reduce parasitic currents and provide a more uniform capacitance over the entire surface area.

Furthermore, the ECQ-E1393KF film capacitor is designed with a hermetically sealed case which provides insulation from outdoor climatic conditions. This helps to ensure that the voltage and frequency of the circuit remain constant and that the operational characteristics of the capacitor remain consistent even when subjected to environmental variations.

Conclusion

In conclusion, the ECQ-E1393KF film capacitor is an efficient, low-cost, and high-frequency-response solution for filtering out high-frequency noise in power supplies and other applications. Its use of a divided-plate-electrode structure and hermetically sealed case to reduce parasitic currents and keep the capacitance uniform further increases its performance. As such, ECQ-E1393KF has become a preferred choice for AC power line filters, power supplies, and other related circuits in the civil and industrial sectors.
