Standard:JIS C 5101, IEC60384) No. 1 Rated Voltage Shown in Rated value. The rated voltage is defined as the maximum voltage which may be applied continuously to the capacitor. 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. 2 Appearance No defects or abnormalities. Visual inspection. 3 Dimension Shown in Rated value. Using Measuring instrument of dimension. 4 Voltage Proof No defects or abnormalities. Measurement Point : Between the terminations Test Voltage : 250% of the rated voltage Applied Time : 1s to 5s Charge/Discharge Current : 50mA max. 5 Insulation Resistance(I.R.) More than 50F Measurement Temperature: Room Temperature Measurement Point : Between the terminations Measurement Voltage : Rated Voltage Charging Time : 1min Charge/Discharge Current : 50mA max. 6 Capacitance Shown in Rated value. Measurement Temperature: Room Temperature Measurement Frequency : 1.0+/-0.1kHz Measurement Voltage : 1.0+/-0.2Vrms 7 Q or Dissipation Factor (D.F.) DF:0.1 max. Measurement Temperature : Room Temperature Measurement Frequency : 1.0+/-0.1kHz Measurement Voltage : 1.0+/-0.2Vrms 8 Capacitance No bias Within +22/-33% The capacitance change should be measured after 5 minutes at each specified temperature stage. Temperature (-55 to +125 ) Characteristics Capacitance value as a reference is the value in marked step.
