Visual inspection
Using calipers and micrometers
No failure should be observed when voltage in the table is
applied between the terminations for 1 to 5 sec., provided the
charge/discharge current is less than 50mA.
Rated Voltage
DC250V

The inslation resisitance should be measured with
DC500V±50V (DC250V±25V in case of rated Voltage:
DC250V, DC450V) and within 60±5 sec. of charging.
The capacitance/D.F. should be measured at a frequency of
1±0.2kHz and a voltage of AC1±0.2V (r.m.s.).
The capacitance measurement should be made at each step
specified in the table.

In accordance with item No.7
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 defects such as heat shock.

Glass Epoxy Board
Fig. 1
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.).
