No Item Specification
(Ref. Standard:JIS C 5101, IEC60384
1 Rated Voltage Shown in Rated value. The rated voltage is defined as the maximum voltage
which may be applied continuously to the capacitor.
When AC voltage is superimposed on DC voltage,
P-P O-P
V or V , whichever is larger, should be maintained
within the rated voltage range.
2 Appearance No defects or abnormalities. Visual inspection.
3 Dimension Within the specified dimensions. 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 5 s
Charge/discharge current : 50mA max.
5 Insulation Resistance(I.R.) More than 10,000M Measurement Point : Between the terminations
Measurement Voltage : DC Rated Voltage
Charging Time : 2 min

6 Capacitance
Shown in Rated value. Measurement Temperature : Room Temperature
Capacitance Frequency Voltage
7 Q 30pF and over : Q 1400
C1000pF 1.0+/-0.1MHz 0.5 to 5.0Vrms
30pF and below : Q 800+20C
C:Nominal Capacitance(pF)
8 Temperature Characteristics Nominal values of the temperature coefficient is shown in The capacitance change should be measured after 5 min
of Capacitance Rated value. at each specified temp. stage.
But,the Capacitance Change under 20/25 is shown in Table A. Capacitance value as a reference is the value in step 3.
Capacitance Drift The capacitance drift is calculated by dividing the differences
Within +/-0.2% or +/-0.05pF between the maximum and minimum measured values in the
(Whichever is larger.) step 1,3 and 5 by the cap. value in step 3.
