Film Capacitors are vital components commonly used across many different industries and electronic applications to provide reliable energy storage and filtering functions. ECQ-E10822KFB is a type of film capacitor widely used in the circuitry of audio-visual equipment and home appliances. This article will provide an in-depth analysis on the application field of ECQ-E10822KFB as well as its working principle.

Application Field of ECQ-E10822KFB

ECQ-E10822KFB is a polyester film capacitor with a rated capacitance of 2200uF and rated voltage of 400V. It is commonly used in sophisticated circuitry which requires the reliability and durability of a film capacitor. Due to its higher capacitance rating, ECQ-E10822KFB has its application in larger-scale home appliances and audio-visual equipment. Specifically, it can be found in power factor correction circuits, welding machines, frequency inverters, photocouplers, and high-power drives. It is also used in capacitor banks and power filters to absorb harmonics and reactive power.

Working Principle of ECQ-E10822KFB

ECQ-E10822KFB works on the principle of electrostatic field. Electric charge is stored between two conductors (plates) separated by a dielectric material, in this case, the polyester film. This stored electric energy creates an electrostatic field which can be used to power various circuits. As the electric charge is stored, it’s strength decreases over time. Thus, the stored energy in the capacitor is consumed over certain period of time. This phenomenon is known as ‘capacitor leakage’. Therefore, it is advised that ECQ-E10822KFB should be replaced after a certain period of time, otherwise it may malfunction and even cause damage to other components.

Conclusion

ECQ-E10822KFB is a high capacity, film capacitor with a rated voltage of 400V and rated capacitance of 2200uF. It is well suited for large-scale applications such as welding machines, frequency inverters and capacitor banks. The working principle of ECQ-E10822KFB is based on electrostatic field and over time, it may experience capacitance leakage which can lead to malfunctioning or even permanent damage of circuits. Therefore, these capacitors should be regularly checked and replaced when necessary.
