Additionally, the ECW-H8242HL is ideal for battery-powered appliances such as portable televisions, CD players, and radio receivers.

Working Principle

The ECW-H8242HL uses a dielectric film, made of polypropylene, which is sandwiched between two metal plates. The dielectric film is resistant to temperature effects and is able to dissipate heat quickly. An AC voltage is applied across the device, and the electric field generated by the voltage causes the electric charges in the dielectric film to move, generating electric current in the metal plates.

The ECW-H8242HL has high dielectric strength, meaning that the device can withstand high voltages without breaking down. The device is also designed with a high degree of capacitance and low loss values, which means that it can hold a charge for a long time and dissipate less energy. Additionally, the capacitor is designed with a large surface area, which helps to reduce the inductance and increase the current capacity.

Common Electrical Characteristics

The ECW-H8242HL has a capacitance range of 2.2 µF to 10µF and a rated voltage of 800V DC. The Rated temperature of the capacitor is -25°C to +90°C. The self-resonance frequency of the device is greater than 500KHz and the maximum permissible ripple current at 25°C is 150mA. The capacitor has a dielectric strength of 5kV (60Hz, 1 minute).

The ECW-H8242HL has a wide range of electrical characteristics, including low ESR values (Equivalent Series Resistance) which make the capacitor a good choice for applications that require low power consumption. Additionally, the ECW-H8242HL has a low dissipation factor (DF) rating which makes it suitable for high-frequency applications.

In summary, the ECW-H8242HL is a polypropylene film capacitor suitable for a range of applications, including DC-DC converters, switch-mode power supplies, and electronic lamps. The capacitor is designed with a high dielectric strength, low ESR values, and low dissipation factor, making it an ideal choice for applications that require low power consumption. Additionally, the capacitor can withstand a wide range of temperatures and has high capacitance and low loss values, making it suitable for long-term, temperature-sensitive applications.
