ECW-H12104HVB

Film capacitors are widely used in the modern electronics industry because of their small size, high insulation, low electrical loss, and their low self-induction. They are typically used in wide variety of commercial and industrial applications such as power supplies, DC-DC converters, low-voltage converters, AC/DC rectifiers, UPS, motors, and switch-mode power supplies. The ECW-H12104HVB is from the ECW family of film capacitors, and is specifically designed for applications requiring a high-performance dielectric.

The ECW-H12104HVB is a four-terminal, high-frequency, polypropylene film capacitor designed specifically for low-voltage power supplies. It offers a high-current rating of 10A and a low-temperature operating range of -40°C to +105°C. The component features a Hermetically Sealed construction which ensures the safety and reliability of the application. The capacitor also offer a low-impedance rating of 5mOhms which helps to reduce external noise interference.

The application field of this capacitor includes automotive, industrial, and consumer electronics. In automotive applications, the ECW-H12104HVB is ideal for use in power driver modules, ECUs, and other low-voltage power supplies, allowing for optimal system performance and reliability. In industrial applications, the capacitor is used in high-frequency switching power supplies, AC/DC rectifiers, and UPS applications. This capacitor offers extended lifetime to meet the demanding operational requirements of these applications. Finally, in consumer electronics, the film capacitor is used in portable power supplies, such as laptops and portable chargers, and in power systems for home and commercial appliances.

The working principle of the ECW-H12104HVB is based on the principle of dielectric material. The capacitor is a non-polarized device, whereby the alternate layers of NPO (nickel ferrite oxide) and PP (polypropylene) dielectric create a barrier for the current to flow across the capacitor. This barrier limits the current from passing through, creating an electrical field which stores energy. This stored energy can then be used by electrical circuits for applications such as decoupling, passing and filtering signals, and protecting electronic circuits from surges and spikes.

The ECW-H12104HVB is hermetically sealed, meaning that the capacitor does not need to be re-filled with fluid, and the dielectric is permanently sealed. The device also contains a self-healing mechanism, which prevents the capacitor from failing due to voltage overstress. This self-healing is enabled by the NPO layer that reacts to voltage spikes and repairs itself. The capacitor also offers a high-value rating of 200μF, which is ideal for applications requiring high-energy storage and high-current ratings.

In conclusion, the ECW-H12104HVB is a four-terminal, high-frequency polypropylene film capacitor designed specifically for low-voltage power supplies. Its hermetically sealed construction ensures reliable operation and the self-healing capability gives additional protection against external power fluctuations. The capacitor offers high-current ratings, a low-temperature operating range, and an extended lifetime, making it ideal for automotive, industrial, and consumer electronic applications.
