“ELECTRICAL CHARACTERISTICS” are available when capacitors’ capacitance values are as shown
above. Since the characteristics may vary with the maximum load current, the working environment,
applicable parts, etc., however, evaluate the characteristics for each application and check the capaci-
tance values.
