ECW-F4154HL

Film Capacitors

Film capacitors, also known as plastic film capacitors or film dielectric capacitors, are components with a dielectric material depending on dielectric plastic film. They are both used for electronic decoupling, energy storage and signal filtering. ECW-F4154HL is one type of film capacitor, specifically designed for motor control applications.

Application Field

ECW-F4154HL film capacitors are ideal for power supply decoupling, bypass, and start-up in various motor applications, such as motors for evaporative coolers, cooling fans for air conditioning system, power-assisted door, electronic trimming and control equipment, pumps, compressors, fitness equipment and energy-saving lamps.

In addition, they can be used in switching power supplies, transportation, emergency lighting, lighting and other small power DC/DC converters, buses and airlines’ lighting, fleet management and location monitoring, PFC enhancers, high-efficiency and high-power audio equipment and other applications.

Working Principle

ECW-F4154HL capacitor consists of two electrodes separated by a dielectric plastic film, both of which conduct electricity. When an electric current passes through the film, an electric field is generated, providing energy storage. The energy stored in the film capacitor decreases as the frequency of the applied current decreases, while the energy stored increases as the frequency of the current increases. This means that the film capacitor can be used to reduce high frequency noise and increase low frequency noise, and the film capacitor works typically as a filter.

The working principle of the ECW-F4154HL film capacitor is similar to that of other film capacitors available on the market, but its unique design means it is more resistant to high temperature operating environments. It is durable, and can operate at temperatures up to 155℃, while also providing stability and good performance over the operating temperature range.

Conclusion

ECW-F4154HL film capacitor is an ideal choice for various motor applications, such as motors for evaporative coolers, cooling fans for air conditioning system, and power-assisted doors. Its working principle is based on a dielectric plastic film which generates an electric field when an electric current passes through it, providing energy storage. Its unique design allows it to operate at high temperatures, and provide stability and good performance over the operating temperature range.
