1 Rated Voltage Shown in Rated value. The rated voltage is defined as the maximum voltage
which may be applied continuously to the capacitor.
When AC voltage is superimposed on DC voltage,
VP-P or VO-P, whichever is larger, should be maintained
within the rated voltage range.

Nominal values of the temperature coefficient is shown in Rated value.
The capacitance change should be measured after 5 min
Characteristics at each specified temp. stage.
of Capacitance
But,the Capacitance Change under 25℃is shown in Table A. In case of applying voltage, the capacitance change should be
measured after 1 min with applying voltage in equilibration of
Capacitance Drift each temp. stage.
Within +/-0.2% or +/-0.05pF Capacitance value as a reference is the value in step 3.
(Whichever is larger.) The capacitance drift is calculated by dividing the differences
between the maximum and minimum measured values in the
step 1,3 and 5 by the cap. value in step 3.
