P-P O-P When AC voltage is superimposed on DC voltage, V or V , whichever is larger, should be maintained within the rated voltage range. 3 Appearance No defects or abnormalities. Visual inspection. 4 Dimension Within the specified dimensions. Using calipers. 5 Dielectric Strength No defects or abnormalities. No failure should be observed when 300% of the rated voltage is applied between the terminations for 1 to 5 seconds, provided the charge/discharge current is less than 50mA. 6 Insulation More than 10,000M or 500 F . The insulation resistance should be measured with a DC Resistance (hichever is smaller) voltage not exceeding the rated voltage at 25 and 75%RH max. and within 2 minutes of charging. 7 Capacitance Within the specified tolerance. The capacitance/Q should be measured at 25 at the frequency and voltage shown in the table.
