Film capacitors play an important role in AC and DC applications due to their stable electrical characteristics and good temperature characteristics. A variety of film capacitors have been developed and employed for different applications. Among them, ECQ-P1H103GZW is one of the most important and widely used film capacitors, suitable for various electronic circuits.

Applications

ECQ-P1H103GZW is mainly used in fields such as high frequency circuit, audio circuit, electronic clock, communication, switch power supply, light dimmer, and the protection circuits of air conditioning and refrigerator. It is also used in power electronic magnetic components, such as filter, damper, and high frequency transformer.

This capacitor has an excellent overall performance, wide frequency bandwidth, high frequency characteristic impedance, and small pulse rise time. Especially, it is suitable for frequency up to 300kHz, and features a small size and light weight. It also provides a high insulation resistance of 10GΩ, so that it can effectively suppress interference and noise on the circuit.

Working Principle

The core structure of ECQ-P1H103GZW capacitor consists of a mylar film and two metal electrodes. The capacitor dielectric material is generally selected for its good insulation, good dielectric properties, and good temperature properties. Theuse of metal electrodes further enhances the electrical characteristics, thermal characteristics, insulation properties, and aging characteristics of the capacitors.

In addition, the use of metal electrodes ensures that the current flow is evenly distributed in the capacitor. This leads to low impedance and prevents decomposition or destruction of the metal electrodes. At the same time, the metal electrodes also enhance the capacitor\'s ability to resist mechanical and electrical vibration.

During the working process, the mylar film is inserted between the two metal electrodes and becomes an effective insulating barrier. As a result, the current between two electrodes passes through the mylar film and is limited by the small area between thefilm and the electrodes. This act constructs an electrical field between two electrodes and forms an equivalent capacitor.

In addition, the voltage is limited by the dielectric strength of the mylar film, thus making ECQ-P1H103GZW a high-voltage capacitor product. Meanwhile, the presence of small capacitors on the surface of the metal electrodes forms a distributed capacitance. This ensures that the electrical characteristics of the capacitors remain stable over temperature and time.

Conclusion

The ECQ-P1H103GZW is the most important and widely used film capacitor in modern circuit design. It is applicable to a variety of AC and DC applications due to its stable electrical and temperature characteristics. Its use of a mylar film and metal electrodes provides unmatched reliability and excellent electrical characteristics, making it the ideal choice for frequency up to 300 kHz.
