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.

Using calipers (GRM02 size is based on Microscope)
No failure should be observed when 250% of the rated voltage
is applied between the terminations for 1 to 5 seconds,
provided the charge/discharge current is less than 50mA.

Dielectric Strength No defects or abnormalities
The insulation resistance should be measured with a DC voltage
not exceeding the rated voltage at reference temperature and
75%RH max. and within 1 minutes of charging, provided the
charge/discharge current is less than 50mA.
