The rated voltage is defined as the maximum voltage that may
be applied continuously to the capacitor.
When AC voltage is superimposed on DC voltage, V

O-P
,
whichever is larger, should be maintained within the rated
voltage range.
Visual inspection
Using calipers
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.

Solder the capacitor to the test jig (glass epoxy board) in
the same manner and under the same conditions as (10). 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 minute. This motion should be
applied for a period of 2 hours in each of 3 mutually
perpendicular directions (total of 6 hours).
Immerse the capacitor in a solution of ethanol (JIS-K-8101) and
rosin (JIS-K-5902) (25% rosin in weight proportion). Preheat at
80 to 120°C for 10 to 30 seconds. After preheating, immerse in
eutectic solder solution for 2±0.5 seconds at 230±5°C, or
Sn-3.0Ag-0.5Cu solder solution for 2±0.5 seconds at 245±5°C.
Preheat the capacitor at 120 to 150°C for 1 minute. Immerse
the capacitor in a eutectic solder or Sn-3.0Ag-0.5Cu solder
solution at 270±5°C for 10±0.5 seconds. Let sit at room
temperature for 24±2 hours, then measure.
• Initial measurement.
Perform a heat treatment at 150+0/–10°C for one hour and
then let sit for 24±2 hours at room temperature. Perform the
initial measurement.

of Termination
No removal of the terminations or other defect should occur.
Solder the capacitor to the test jig (glass epoxy board) using a
eutectic solder. Then apply 10N* force in parallel with the test
jig for 10±1 sec. 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.
