Ordinary capacitors are a kind of static charge storage medium, and there may be charges. This is its characteristic. It has a wide range of uses. It is an indispensable electronic component in the fields of electronics and electricity. Farad capacitors are mainly used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, DC blocking and other circuits.

A supercapacitor is an electrochemical element that stores energy through polarized electrolytes. It can be used as a power source with special properties between traditional capacitors and batteries. The energy storage process is reversible and can be repeatedly charged and discharged. Hundreds of thousands of times.

When choosing the size of the capacitor, many factors need to be considered, among which the high working voltage, the working cut-off voltage, the average discharge current, and the discharge time are several factors that need to be considered in particular.

Although supercapacitors have relatively low internal resistance, compared with electrolytic capacitors, their internal resistance is still relatively large. When applied to pulsating current occasions, it is easy to cause internal heating of the capacitor. As a result, the electrolyte inside the capacitor is decomposed, the internal resistance increases, and the life of the capacitor is shortened. In order to ensure the service life of the supercapacitor, the supercapacitor manufacturer should ensure that the temperature rise on the surface of the capacitor does not exceed 5°C when it is used in pulsating occasions.

The use of supercapacitors in the supercapacitor module within the specified parameter range can effectively prolong the life of the supercapacitor. Usually, supercapacitors have a similar structure to ordinary electrolytic capacitors. The liquid electrolyte is sealed in an aluminum shell. After a few years, the electrolyte will gradually dry up. This is the same as ordinary electrolytic capacitors, which will lead to internal resistance of the capacitor. increase and make the capacitor completely ineffective.
