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,
P-P O-P
V or V , whichever is larger, should be maintained
within the rated voltage range.
Visual inspection.
Using calipers. (GRM02 size is based on Microscope)

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.
(1)Temperature Compensating Type
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.

· Initial measurement for high dielectric constant type
Perform a heat treatment at 150+0/-10°C for 1h and then
let sit for 24+/-2h at room temperature, then measure.
Solder the capacitor on the test substrate shown in Fig.3.
