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
P-P
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
(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 insulation resistance should be measured with a DC
voltage not exceeding the rated voltage at 25°C and 75%RH
max. and within 2 minutes of charging.
The capacitance/Q/D.F. should be measured at 25°C at the
frequency and voltage shown in the table.

Characteristics
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 steps 1 through 5, 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 the
steps 1, 3 and 5 by the cap. value in step 3.

(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.
• Initial measurement for high dielectric constant type.
Perform a heat treatment at 150+0/-10°C for one hour and
then set for 24±2 hours at room temperature.
Perform the initial measurement.
For Bonding

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 10±1 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.
