Film capacitors, as a type of electrical component, are widely used in various industries, especially for electronic applications. Their superior characteristics, such as excellent stability in environmental conditions, low losses and excellent insulation, make them ideal candidates for some applications. In this article, we will focus on the application field and working principle of ECW-H16473HV film capacitors.

Application field

ECW-H16473HV film capacitors are widely used in AC/DC power supply, energy storage system, UPS, LED lamps and other electronic appliances. They offer excellent stability, high cycle life and low ESR that meet the requirements of switching power supply applications. Besides, these capacitors also keep high safety margin and respect high-power operation as well as large current spikes.

Working principle

The working principle of ECW-H16473HV film capacitors is based on an electrical field established between the capacitors’ separated electrodes. The electrostatic field is created by the separation of the two electrodes as they are separated by an insulating material. This electrostatic field allows electricity to flow from one electrode to the other, while the voltage across the capacitor is determined by the ratio of the capacitance to the dielectric value. The dielectric material contained in the capacitor gives it its distinct capacitance value that determines the capacitance of the capacitors.

When AC voltage is applied to the capacitor, the voltage changes the capacitance of the capacitor. As the voltage increases, the electric charge between the two electrodes increases, causing the capacitance of the capacitor to increase. At the same time, the electric current also increases as the amount of charge increases. The current flowing through the capacitor depends mainly on the capacity of the capacitor, its value, and the frequency of the voltage source.

The current passing through the capacitor causes an electrical field to be generated in the dielectric material, which acts to oppose the applied voltage. This opposition is what is referred to as the capacitance of the capacitor. The opposition to the applied voltage decreases as the applied voltage increases, resulting in a diminished amount of current passing through the capacitor. This phenomenon is also referred to as capacitive reactance.

The ECW-H16473HV film capacitors are designed to offer great stability in environmental conditions. They have high insulation, high power, and high cycle life. They also feature lower ESR and improved stability even in demanding conditions.

In summary, the ECW-H16473HV film capacitors are widely applied in AC/DC power supply, energy storage systems, LED lamps and other electronic applications. The working principle of the capacitor depends on electric field that is created when the two electrodes of the capacitor becomes separated by an insulating material. The capacitance value of the capacitor is determined by the ratio of the capacitance to the dielectric value. The appreciable features such as high insulation, high power, and high cycle life make these capacitors ideal candidates for some applications.
