Introduction to Film Capacitors

A film capacitor is a type of capacitor designed to store and release electric energy. They use a thin film of conductive material such as plastic or metal to insulate and separate two metal plates, each attached to one end of the same film. This way, electrical charge is stored inside the film. These capacitors have several advantages, including high capacitance per unit volume, low electrical losses, low temperaturecoefficient, and low parasitic elements like inductance or resistance. They are also much smaller than comparable electrolytic capacitors.

Applications of Film Capacitors

Film capacitors are commonly used for power conditioning and supply, as well as filtering and bypassing. In electronic equipment, such as amplifiers and audio circuits, they are used to reduce supply rail ripple. In industrial applications, like motor control, they can be used to reduce voltage surges. Film capacitors can also be used for timing applications such as switching circuits, and for light dimming and flicker control in fluorescent ballasts.

ECW-H10393HVB

The ECW-H10393HVB is a high voltage, medium capacitance film capacitor, specifically designed for the purpose of protecting AC LED drivers from extreme supply voltage fluctuations. It is rated at 1000 volts DC and has a capacitance of 2.2 microfarads. The capacitor is constructed with two opposing layers of highly capacitive, ultra-thin metallic films and dielectric protection coating.

Working Principle of ECW-H10393HVB

When extreme voltage is applied to the capacitor, the opposing layers become charged up, producing an internal electric field between them. The stored energy holds the two layers apart, preventing them from coming in contact with each other. The capacitance is then responsible for smoothing out supply line noise, while also absorbing any voltage spikes that may occur. The ECW-H10393HVB is designed to handle these extreme voltages without damaging the sensitive components inside AC LED drivers. The ultra-thin films and dielectric protection also help to prevent any failure or breakdown, while ensure long service life.

Conclusion

Film capacitors are used in a wide variety of applications where their small size, high performance, and reliability are seen as important factors. The ECW-H10393HVB is a specific type of film capacitor that offers excellent protection for AC LED drivers against supply line noise and voltage spikes. Its high voltage rating and high capacitance give it the ability to absorb shocks and prevent breakdowns, all while offering long service life.
