1 Rated Voltage
Specification
Shown in Rated value.
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.

The capacitance change should be measured after 5 minutes at each specified temperature stage.
Capacitance value as a reference is the value in "*" marked step.
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 capacitance
value in step 3.
