2 Rated Voltage See the previous pages. 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.
3 Appearance No defects or abnormalities. Visual inspection.
4 Dimension Within the specified dimensions. Using calipers.
5 Dielectric Strength No defects or abnormalities. 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.

10 Adhesive Strength of No removal of the terminations or other defect should occur. Solder the capacitor on the test jig (glass epoxy
Termination board)shown in Fig.3 using an eutectic solder. Then apply
10N* force in parallel with the test jig for 10+/-1sec.
The soldering should be done either with an iron or using the
reflow method and should be conducted with care so that the
soldering is uniform and free of defects such as heat shock.
