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 300% of the rated voltage Applied Time 1s to 5s Charge/discharge current 50mA max. More than 10000M 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 Q 1000 Room Temperature (D.F.) Measurement Frequency 1.0+/-0.1kHz Measurement Voltage 1.0+/-0.2Vrms 8 Temperature No bias Nominal values of the temperature coefficientis is The capacitance change should be measured after 5 min at each specified temp. stage. Characteristics of shown in Rated value. But, the Capacitance Change Capacitance value as a reference is the value in marked step. Capacitance under Reference Temperature is shown inTable A. Capacitance Drift The capacitance drift is calculated by dividing the differences between the maximum and minimum Capacitance Drift: Within +/-0.2% or +/-0.05pF measured values in the step 1,3 and 5 by the cap. value in step 3. (Whichever is larger.) Measurement Voltage Less than 1.0Vrms (Refer to the individual data sheet) 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 GRM21B7U1H393JA01-01A 2
