High Dielectric
Constant Type
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.

Characteristics
of Capacitance
In case of applying voltage, the capacitance change should be
measured after 1 min with applying voltage in equilibration of
each temp. stage.
