Handling Precautions and Guidelines
For safety application, please contact Shandong Godencell directly for any technical specifications, handling precautions and guidelines critical to application.
1. Polarity and voltage of supercapacitor
(1) Supercapacitor have polarities
Do not apply a reverse or AC voltage. If a reversed voltage is applied to a capacitor for a long period of time, then its life will be reduced and critical failures such as electrolyte leakage may occur.
(2) Do not apply an over-voltage (a voltage exceeding the rated voltage )
If voltage exceeding the rating is applied to the capcacitor for a long time, then its life will be reduced and critical failures such as electrolyte leakage or physical damage due to gas generated by electrochemical reaction or explosion may occur.
2. Circuits through which ripple currents pass
When using a supercapacitor in a circuit through which ripple currents pass, monitor the allowable temperature rang. The internal resistance of electric supercapacitors is higher than that of electrolytic capacitors. Supercapacitors may generate heat due to ripple currents.
3. Effect of ambient temperature on the supercapacitor
Supercapacitor life is affected by usage temperatures. Generally speaking, supercapacitor life is approximately doubled when the temperature is decreased by 10 oC. Therefore, lower the usage temperature as much as possible. Using supercapacitors beyond the guaranteed range may cause rapid deterioration of their characteristics and cause them to break down. The temperature referred to here includes the ambient temperature within the equipment, the heat prouduced by heat generating devices (power transistor, resistors, etc.), self-heating due to ripple currents, etc. Take all of these factors into consideration when checking the supercapacitor’s temperature. Do not place any heat generating devices on the back of the supercapacitor.
