In today\'s world of modern technology, film capacitors can be found in many electrical devices. The ECQ-E2155JF film capacitor is one such device and is widely used in a variety of applications. This article will discuss the application field of the ECQ-E2155JF film capacitor and its working principle.

Application Field

Film capacitors, like the ECQ-E2155JF, are most commonly used in AC line power supply applications. Thanks to their high efficiency and low profile, film capacitors are widely used in consumer electronics, offices, and industrial robotics. Additionally, film capacitors show excellent performance in higher frequency applications, such as switching power supplies, LED lighting, and other AC-DC converters.

The ECQ-E2155JF film capacitor offers a stable electrical performance over time, which is essential in electronic equipment that requires long-term functionality. Thanks to its self-healing technology, the ECQ-E2155JF film capacitor can repair any surface defects during a power outage and extend the life of the device. The product is also UL approved and is recognized as a robust film capacitor.

Working Principle

A film capacitor consists of two metallic surfaces, separated by a dielectric membrane. This membrane is composed of a thin coating of metalized film and acts as an electrical insulator. When a voltage is applied to the two metal surfaces, an electric field is generated, creating an electrical charge.

When the applied voltage exceeds the dielectric\'s insulation limit, the electrostatic field overcomes the membrane\'s resistance. This “punch-through” causes a current arc, which can damage the capacitor. To prevent this from happening, the ECQ-E2155JF employs technological features that self-heal any damages caused by the punch-through.

The ECQ-E2155JF also utilizes a unique construction design that helps to reduce losses while maintaining reliability. This helps to achieve a low distortion factor and prevent loss of energy. The product also features an electrostatic safety shield that prevents any abnormal electrical energy from passing through, ensuring user safety and long-term stability.

In conclusion, the ECQ-E2155JF film capacitor is an essential electronic device that is widely used in a variety of applications. It offers reliable performance and a long service life thanks to its self-healing technology and electrostatic safety shield. Therefore, the ECQ-E2155JF is an excellent choice for use in AC line power supply applications, consumer electronics, offices, and industrial robotics.
