3 Appearance
No defects or abnormalities.
Test Method
Standard Temperature:20℃
(R6,R7,R9,C7,C8,F5,L8:25℃)
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, VP-P or VO-P,
whichever is larger, should be maintained within the rated voltage range.
Visual inspection.
4 Dimension
Within the specified dimensions.
Using calipers. (GRM02 size is based on Microscope)
5 Dielectric Strength
No defects or abnormalities.
No failure should be observed when 300% of the rated voltage
(temperature compensating type) or 250% of the rated voltage
(high dielectric constant type) is applied between the
terminations for 1 to 5 seconds, provided the charge/discharge
current is less than 50mA.
6 Insulation
Resistance
C≦0.047μ F:More than 10000MΩ
C>0.047μ F:More than 500Ω·F
C:Nominal Capacitance
The insulation resistance should be measured with a DC voltage
not exceeding the rated voltage at 20℃/25℃ and 75%RH max.
and within 2 minutes of charging, provided the charge/discharge
current is less than 50mA.
7 Capacitance
Within the specified tolerance.
The capacitance/D.F. should be measured at 20℃/25℃ at the
