Description

Technical Field

[0002] Capacitors play a variety of important roles in electronic circuits and systems. They can be used to store electrical energy: capacitors can store charge and electrical energy. This property allows capacitors to release energy when needed, such as in flash lamps, pulse forming circuits, and some power supply circuits. And filtering: in power supply circuits, capacitors are often used as filtering elements to reduce the ripple voltage in the power supply and provide a stable operating voltage for the circuit. Capacitors usually consist of two conductive plates (or electrodes) separated by a layer of insulating medium. This insulating medium can be solid, gas, or liquid. For some types of capacitors (such as electrolytic capacitors or wet capacitors), the insulating medium is a liquid electrolyte. However, when the capacitor is placed inside the casing, the poured liquid electrolyte solidifies and has a small contact area with the capacitor, making the fixed installation effect poor.
