No failure should be observed when 150% of the rated voltage
(200% of the rated voltage in case of rated voltage: DC250V,
120% of the rated voltage in case of rated voltage: DC1kV) is
applied between the terminations for 1 to 5 sec., provided the
charge/discharge current is less than 50mA.

Dielectric Strength No defects or abnormalities
The insulation resistance should be measured with DC500±50V
(DC250±25V in case of rated voltage: DC250V) and within 60±5
sec. of charging.

Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 1.
Then apply 10N force in the direction of the arrow.
The soldering should be done using the reflow method and
should be conducted with care so that the soldering is uniform
and free of defects such as heat shock.

Appearance No defects or abnormalities
Capacitance Within the specified tolerance
Solder the capacitor to the test jig (glass epoxy board).
The capacitor should be subjected to a simple harmonic motion
having a total amplitude of 1.5mm, the frequency being varied
uniformly between the approximate limits of 10 and 55Hz. The
frequency range, from 10 to 55Hz and return to 10Hz, should be
traversed in approximately 1 min. This motion should be applied
for a period of 2 hrs. in each of 3 mutually perpendicular
directions (total of 6 hrs.).
