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).

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. *5N (LLL18 and LLA/LLM Series)

The capacitance change should be measured after 5 min. at
each specified temperature stage.
The ranges of capacitance change compared with the 25°C
value over the temperature ranges shown in the table should
be within the specified ranges.
• Initial measurement.
Perform a heat treatment at 150+0/-10°C for one hour and then

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, VP-P or VO-P,
whichever is larger, should be maintained within the rated
voltage range.
