Supercapacitor (Electrical Doule-LayerCapacitor) is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection. 


Supercapacitor Usage Precautions
1. Supercapacitors have a fixed polarity. The polarity should be confirmed before use.
2. Supercapacitors should be used at nominal voltage:
When the capacitor voltage exceeds the nominal voltage, it will cause the electrolyte to decompose, while the capacitor will heat up, the capacity will decrease, and the internal resistance will increase, the life will be shortened, and in some cases, the performance of the capacitor will collapse.
3. Supercapacitors should not be used in high-frequency charging and discharging circuits. High-frequency rapid charging and discharging will cause internal heating of capacitors, capacity attenuation, internal resistance increase, and in some cases, capacitor performance will collapse.
4, the life of super capacitors:
The ambient temperature has an important influence on the life of the supercapacitor. Capacitors should be kept away from heat sources as much as possible.
5. Voltage drop when the supercapacitor is used as a backup power supply:
Since the supercapacitor has a large internal resistance, there is a voltage drop at the moment of discharge, ΔV=IR.
6, the use of ambient gases:
Supercapacitors should not be placed in locations where the relative humidity is greater than 85% or contain toxic gases, which can lead to corrosion of the leads and capacitor housings, resulting in open circuits.
