The rated voltage is defined as the maximum voltage that may
be applied continuously to the capacitor.

Rated Voltage
See the previous pages.
When AC voltage is superimposed on DC voltage, VP-P or VO-P
whichever is larger, should be maintained within the rated
voltage range.

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 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.

• 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.
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 10±1 sec.
