Test Method(Ref. Standard:JIS C 5101, IEC60384）
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, V(peak to peak) or V(zero to peak),
whichever is larger, should be maintained within the rated voltage range.
