The rated voltage is defined as the maximum voltage that may
be applied continuously to the capacitor.
When AC voltage is superimposed on DC voltage, V

or V
O-P
,
whichever is larger, should be maintained within the rated
voltage range.
Visual inspection
Using calipers
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.

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.

Capacitance

Characteristics Capacitance
Drift
The capacitance change should be measured after 5 min. at
each specified temperature stage.
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.

The insulation resistance should be measured with a DC

max. and within 2 minutes of charging.
