Within the specified dimension
No failure should be observed when 300%(*) of the rated volt-
age is applied between the terminations for 1 to 5 seconds,
provided the charge/discharge current is less than 50mA.

Dielectric Strength No defects or abnormalities
The insulation resistance should be measured with a DC
voltage not exceeding the rated voltage at 25D and standard
humidity and within 2 minutes of charging.

Capacitance
Change
The temperature coefficient is determined using the
Within the specified tolerance (Table A-6)
Within the specified tolerance (Table A-6)
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.
The capacitance drift is calculated by dividing the differences
between the maximum and minimum measured values in steps
1, 3 and 5 by the capacitance value in step 3.

No removal of the terminations or other defects should occur.
Solder the capacitor on the test jig (glass epoxy board) shown
in Fig. 1 using an 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.
