Dielectric Strength
No failure should be observed when 300% of the rated
voltage is applied between the terminations for 1 to 5
seconds, provided the charge/discharge current is less
than 50mA.

Characteristics
The temperature coefficient is determind using the
capacitance measured in step 3 as a reference.
When cycling the temperature sequentially from step 1
through 5 the capacitance should be within the specified
tolerance for the temperature coefficient and capacitance
change as Table A-1.

Coefficent
The capacitance drift is caluculated by dividing the
differences betweeen the maximum and minimum measured
values in the step 1,3 and 5 by the cap. value in step 3.

Adhesive Strength of
Termination
Solder the capacitor on the test jig (glass epoxy
board)shown in Fig.3 using an eutectic solder. Then apply
10N* force in parallel with the test jig for 10+/-1sec.
10
No removal of the terminations or other defect should occur.
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(GQM188)
Solder the capacitor on the test jig (glass epoxy board) in the
same manner and under the same conditions as (10).

Appearance No defects or abnormalities.
Capacitance Within the specified tolerance.
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

30pFmax.: Q≧800+20C
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 3
mutually perpendicular directions(total of 6 hours).
Solder the capacitor on the test jig (glass epoxy board)
shown in Fig.1 using an eutectic solder. Then apply a force
in the direction shown in Fig 2. The soldering
should be done by the reflow method and should be
conducted with care so that the soldering is uniform and free
of defects such as heat shock.
