Standard:JIS C 5101, IEC60384 Shown in Rated value. The rated voltage is defined as the maximum voltage which may be applied continuously to the capacitor. 1 Rated Voltage When AC voltage is superimposed on DC voltage, V(peak to peak) or V(zero to peak), whichever is larger, should be maintained within the rated voltage range. 2 Appearance No defects or abnormalities. Visual inspection 3 Dimension Shown in Dimension. 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. More than 500 F Measurement Temperature Room Temperature 5 Insulation Resistance(I.R.) Measurement Point Between the terminations (Room Temperature) Measurement Voltage Rated Voltage Charging Time 2min 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 Measurement Temperature 7 Q or Dissipation Factor DF 0.025 Room Temperature (D.F.) Measurement Frequency 1.0+/-0.1kHz Measurement Voltage 1.0+/-0.2Vrms 8 Temperature No bias Shown in Rated value. The capacitance change should be measured after 5 min at each specified temp. stage. Characteristics of Capacitance value as a reference is the value in marked step. Capacitance Measurement Voltage Less than 1.0Vrms (Refer to the individual data sheet) Pre-treatment Heat treatment:Perform a heat treatment at 150+0/-10C for 1hour and then let sit for 24+/-2hours at room temperature, then measure. Temperature Step No removal of the terminations or other defect should occur. Mounting method Solder the capacitor on the test substrate 9 Adhesive Strength of Termination Applied Force 10N Holding Time 10+/-1s Applied Direction In parallel with the test substrate and vertical with the capacitor side GRM21BR71E474MA01-01A 2
