ECQ-B1H822JF

Film capacitors are widely used in many applications due to their superior electrical properties, superior dielectric insulation properties, and high temperature stability. The ECQ-B1H822JF film capacitor is one of the most popular models for industrial applications. This article will discuss the application field and working principle of this device.

Application Field of the ECQ-B1H822JF Film Capacitor

The ECQ-B1H822JF film capacitor is designed for use in high power electronic equipment, such as switching converters, inverters, UPS systems, and arbitrary waveform generators. It can also be used in audio-video systems, LED lighting, telecom equipment, LCD television sets, switching power supplies, car radios, and other consumer electronic products.

The device\'s high ripple current capability, combined with its high temperature stability and long life, makes it an ideal choice for use in a wide range of applications. The device is also well suited for use in portable electronic equipment, due to its low ESR and low equivalent series resistance characteristics. The device has a temperature rating of -55 to +125°C, and can handle up to 1,000V peak AC voltage.

Working Principle of the ECQ-B1H822JF Film Capacitor

The ECQ-B1H822JF film capacitor utilizes a metallized polypropylene film, which is then formed into a cylindrical canister. This film is coated with an electrical insulating material, which provides the capacitor with its electrical characteristics. The canister itself is made from an electrically non-conductive plastic, which is used to protect the film from the environment.

The capacitor is then connected to an electrical circuit. When an electric current is sent through the circuit, it creates a magnetic field around the capacitor. This magnetic field causes the charges on the film to separate, creating an electric field between the two electrodes (the outer canister and the inner film). This electric field is what stores the electric energy, and is what allows the capacitor to act as an electrical component. The capacitor is charged and discharged based on the level of current in the circuit.

The top electrode of the ECQ-B1H822JF film capacitor is electrically connected to the circuit, while the bottom electrode is connected to ground. When the circuit is supplied with alternating current, the capacitance of the device will oscillate between two levels. This oscillation allows the capacitor to store and release energy, like a battery, but without a battery\'s need for periodic charging.

Conclusion

The ECQ-B1H822JF film capacitor is designed for use in a wide variety of applications. Its high ripple-current capability, combined with its high temperature stability and long life, make it an ideal choice for use in portable and industrial electronics. The device\'s metallized polypropylene film, along with its dielectric insulation material, provide the device with its electrical characteristics. The device is able to store and release energy, like a battery, but without the need for periodic charging.
