No failure should be observed when 300% of the rated voltage
(5C) or 250% of the rated voltage (R7) is applied between the
terminations for 1 to 5 seconds, provided the charge/discharge
current is less than 50mA.

The capacitance change should be measured after 5 min. at
each specified temperature stage.
(1) Temperature Compensating Type
The temperature coefficient is determined using the capaci-
tance measured in step 3 as a reference. When cycling the
temperature sequentially from step1 through 5, the capacitance
should be within the specified tolerance for the temperature
coefficient and capacitance change as Table A.

(2) High Dielectric Constant Type
The ranges of capacitance change compared with the above
25°C value over the temperature ranges shown in the table
should be within the specified ranges.
No removal of the terminations or other defect should occur.
Solder the capacitor to the test jig (glass epoxy board) shown in
Fig.1 using a eutectic solder. Then apply 5N force in parallel with
the test jig for 10T1 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.
