•Initial measurement for high dielectric constant type
Perform a heat treatment at 150 +0/–10°C for one hour and
then set for 24±2 hours at room temperature.
Perform the initial measurement.
Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 1a using a 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.
*1N: GRM02, 2N: GRM03, 5N: GRM15/GRM18
No removal of the terminations or other defects should occur.

Solder the capacitor on 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
