Film capacitors are commonly used in electrical and electronic circuits to store and release energy. They are one of the most widely used capacitor types due to their superior characteristics when compared to traditional capacitor types. ECW-H20242HV is a type of film capacitor specifically designed for applications in high voltage circuits. The ECW-H20242HV application field and working principle are discussed in this article.

Construction

The ECW-H20242HV is a multi-layered film capacitor constructed from high-density polyethylene (HDPE) film. It has a flat housing, dielectric materials, terminal pins, and an overvoltage protection layer. The HDPE film provides superior construction durability and low dielectric absorbability. The overvoltage protection layer can help protect the capacitor from dielectric breakdown due to voltage spikes or overvoltages.

Application Field

The ECW-H20242HV is designed for applications in high-voltage circuits. It is the ideal capacitor for applications with drive currents up to 5000A rms, voltage ratings up to 700V DC, and operating temperatures ranging from –25°C to +85°C. Applications include electrical motor controllers, industrial servo motor controllers, welders, power converter circuits, backlighting inverters, DCDC converters, and power modules. It is also suitable for use in applications in the automotive industry.

Working Principle

The ECW-H20242HV operates by storing energy in the form of an electrical field. When current passes through the capacitor, a charge is stored between two metallic plates, separated by an insulating material. The charge builds up until it is discharged, when the energy stored is released. The ECW-H20242HV has a dielectric absorption rate of 0.4 and a dielectric resistance of 5 x 10⁸Ω. This makes it highly effective at storing energy and discharging it safely and quickly.

Leakage Current and Heat Dissipation

The ECW-H20242HV has a low leakage current of only 20% of rated capacitance and rated voltage. This ensures efficient operation and minimizes power loss. Heat dissipation is also low, with a maximum surface temperature of T110°C. This provides additional protection against over-heating and helps ensure stable performance during operation.

Conclusion

The ECW-H20242HV is a high-voltage film capacitor designed for use in motor controllers, servo controllers, welders, inverters, power converters, and other power electronics applications. It features good construction durability, low dielectric absorbability, and a low leakage current. It is capable of handling up to 5000A rms, 700V DC, and an operating temperature range of –25°C to +85°C. The ECW-H20242HV is an effective and reliable choice for power module applications.
