Reference Temperature : 25D
(B1, B3, F1 : 20D)
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
whichever is larger, should be maintained within the rated
voltage range.
Visual inspection
Using calipers
No failure should be observed when 250% of the rated voltage
is applied between the terminations for 1 to 5 seconds,
provided the charge/discharge current is less than 50mA.
The insulation resistance should be measured with a DC voltage
not exceeding the rated voltage at Reference Temperature and
75%RH max. and within 1 minutes of charging, provided the
charge/discharge current is less than 50mA.
The capacitance should be measured at Reference
Temperature at the frequency and voltage shown in the table.
The D.F. should be measured at Reference Temperature at the
frequency and voltage shown in the table.
The capacitance change should be measured after 5min. at
each specified temp. stage.
The ranges of capacitance change compared with the
Reference Temperature value over the temperature ranges
shown in the table should be within the specified ranges.
In case of applying voltage, the capacitance change should be
measured after 1 more min. with applying voltage in
equilibration of each temp. stage.

#Initial measurement for high dielectric constant type
Perform a heat treatment at 150 W0/Y10°C for one hour and
then set for 48T4 hours at room temperature.
Perform the initial measurement.
