Specification
Test Method
(Ref. Standard:JIS C 5101, IEC60384）
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,
V
P-P
or V
O-P
, whichever is larger, should be maintained
within the rated voltage range.

Characteristics
of Capacitance
But,the Capacitance Change under 25℃ is shown in Table A.
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.
No bias
Nominal values of the temperature coefficient is shown in Rated value. The capacitance change should be measured after 5 min
at each specified temp. stage.
In case of applying voltage, the capacitance change should be
measured after 1 min with applying voltage in equilibration of
each temp. stage.
Capacitance value as a reference is the value in step 3.
