11 96 HVC ENYCAP CHARGING VOLTAGE AT DIERENT TEMPERATURES OPERATING TEMPERATURE RANGE C UP TO C C UP TO 6 C 6 C UP TO 7 C/8 C Charge voltage 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. or 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. () n... number of cells DERATING Working voltage at temperatures above 6 C should be below rated voltage U R. A deratingfactor of. mv/ C per cell is recommended. PRODUCT AND MOUNTING CHARACTERISTICS Attention: parts are precharged at delivery handle appropriate. At delivery products are precharged and voltage over terminals is near nominal voltage. Short circuiting of product terminals is permitted. Do not short circuit permanently. Short circuiting of charged cells may heat up the cells. Cells will fulfill UL T cell < C due to self heating in case of short circuiting. or printed circuit board mounting it has to be taken into account, that for certain form factors top and bottom of products may not be insulated. Capacitor disposal methods should be in accordance with local and state regulations. Table 6. Note () n... number of cells cell U R. V cells U R.6 V cells U R.9 V > cells U R.
