See the previous pages.
When AC voltage is superimposed on DC voltage, V or V ,
whichever is larger, should be maintained within the rated
voltage range.

Within the specified dimensions
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.

Dielectric Strength No defects or abnormalities
The insulation resistance should be measured with a DC
voltage not exceeding the rated voltage at 25D and 75%RH
max. and within 2 minutes of charging.

Temperature Compensating Type
The temperature coefficient is determined using the
capacitance measured in step 3 as a reference.
When cycling the temperature sequentially from step 1 through
5, (5C: W25 to 125D: other temp. coeffs.: W20 to 125D) the
capacitance should be within the specified tolerance for the
temperature coefficient and capacitance change as in 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.

Solder the capacitor to the test jig (glass epoxy board) shown in
Fig. 1 using a eutectic solder. Then apply a 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.
