Given the rated voltage, rated temperature, and 1,000 hours, the lifetime can be extended by derating the voltage and/or the operating temperature. The example here requires an ambient temperature of

Should a supercapacitor be used at a low temperature? As a result, it is recommended to use the supercapacitor at the lowest temperature possible to decrease internal degradation and ESR
Customer Service
10°C increase in operating temperature can reduce the lifespan of supercapacitors by half. Therefore, strive to operate them in cooler environments below the maximum rated temperature.
Customer Service
At present, com-mercially available non-aqueous superca-pacitors are rated for a minimum operat-ing temperature of –40 °C. A capability to operate at lower temperatures would be desirable for
Customer Service
Super capacitors are resistant to high temperatures and have low losses. They can be used in car recorders, smart instruments, vacuum switches, digital cameras, motors, UPS, electric toys, etc.
Customer Service
This temperature is measurable as core temperature in the center of a capacitor body. The higher the core temperature, the faster the evaporation, and the shorter the lifetime.
Customer Service
As a result, it is recommended to use the supercapacitor at the lowest temperature possible to decrease internal degradation and ESR increase. If this is not possible, decreasing the applied voltage to the
Customer Service
Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature.
