Item
Rated Voltage
Specification
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.

Temperature Characteristics
of Capacitance
Nominal values of the temperature coefficient is shown in Rated value. The capacitance change should be measured after 5 minutes
But,the Capacitance Change under 20℃ is shown in Table A.
at each specified temp. stage.
Capacitance value as a reference is the value in step 3.
Capacitance Drift
Within +/-0.2% or +/-0.05pF
(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.
