Film capacitors, also known as film dielectric capacitors, are capacitors with a thin insulating plastic film as the dielectric material, which is mainly used for AC circuit and pulse circuit. The application field and working principle of ECQ-P1H681JZ belong to this type.

The ECQ-P1H681JZ film capacitor, which is a kind of capacitance element used in AC circuit, is a temperature compensation polymer film capacitor. It is featured by high accuracy, stability, low dissipation factor and good frequency characteristic. The capacitance range of the film capacitor is 0.47uF-1.0uF, and the voltage range is 400VAC. The outer cover of the capacitor is made of non-flammable plastic material, with high temperature resistance and small ripple current. Also, it is compact in structure and easy to install.

In terms of working principle, film capacitors are formed by coating the surface of insulating film with electrodes. When there is excess voltage on the capacitor as a result of current being applied to the circuit, electric charges which are positive and negative from the circuit accumulate on the capacitor plates, forming an electric field between them. The insulating film of the capacitor has the property of resisting the flow of electrons, and therefore, the capacitance of the capacitor changes. In this way, the electric energy is stored in the capacitor.

Due to its excellent performance, film capacitors are used in many applications, such as AC circuit, DC circuit, low frequency, power frequency, stabilization and strengthening, filtering and so on. In AC circuits, the capacitor can act as a current limiter to prevent damage to circuit components when voltage surges. In DC circuits, the capacitor can filter the ripple current and ensure the stability of the entire circuit. In low frequency circuits, the capacitor can improve the response of circuit waveforms, and in power frequency circuits, it can improve the resonance of the circuit.

The application and working principle of ECQ-P1H681JZ are typical for film capacitors. Thanks to its advantages such as high accuracy, good stability, low dissipation factor and frequency characteristics, it is an ideal choice for AC, DC, low frequency and power frequency circuit. And with its compact structure and easy installation, it is extensively used in all kinds of electronic equipment.
