The common capacitor is a kind of static charge storage medium, which may exist charge. This is its feature. It has a wide range of applications. It is an indispensable electronic component in the field of electronics and power. Farad capacitor It is mainly used in power filter, signal filter, signal coupling, resonance, filter, compensation, charge discharge, energy storage, DC isolation and other circuits.

Supercapacitor is an electrochemical element that stores energy through polarized electrolyte. It can be used as a power supply with special performance between traditional capacitors and batteries. The energy storage process is reversible and can be recharged and discharged hundreds of thousands of times repeatedly.

When selecting the capacitor size, many factors need to be considered, including high operating voltage, operating cut-off voltage, average discharge current, discharge time, etc.

Although supercapacitor has relatively low internal resistance, its internal resistance is relatively large compared with electrolytic capacitor. When it is used in the situation of pulsating current, it is easy to cause internal heating of capacitor. As a result, the electrolyte inside the capacitor is decomposed, the internal resistance is increased, and the life of the capacitor is shortened. Super capacitor manufacturer In order to ensure the service life of the capacitor, the temperature rise on the surface of the capacitor shall not exceed 5 ℃ when it is applied to pulsating occasions.

Super capacitor module Using supercapacitors within the specified parameters can effectively extend the life of supercapacitors. Generally, supercapacitors have a structure similar to that of ordinary electrolytic capacitors. They are sealed with liquid electrolyte in an aluminum shell. After several years, the electrolyte will gradually dry up, which is the same as that of ordinary electrolytic capacitors. This will increase the internal resistance of the capacitor and make the capacitor completely invalid.
