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,

at each specified temp. stage.

of Capacitance

But,the Capacitance Change under 20℃ is shown in Table A.

In case of applying voltage, the capacitance change should be

measured after 1 min with applying voltage in equilibration of

each temp. stage.

Within +/-0.2% or +/-0.05pF

Capacitance value as a reference is the value in step 3.

(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.
