Note
• Charge and discharge cycles at room temperature (RT) - maximal 50 000 cycles at room temperature allowed!
Notes
• Capacitor is polarized, product will be damaged if reverse charged
• Voltages higher than specified need to be avoided; otherwise reduction of life time, internal gas generation or damage of HVC hybrid
capacitor will occur
• For other operating temperatures, a temperature derating factor has to be considered for correct charging voltage
• Surge voltage is only allowed a few seconds per day, but not as a charging process

DERATING
Working voltage at temperatures above 60 °C should be below rated voltage U
R
. A derating-factor of -1.5 mV/°C per cell is
recommended.
