The rated voltage is defined as the maximum voltage that may
be applied continuously to the capacitor.
When AC voltage is superimposed on DC voltage, V
P-P
or V
O-P
,
whichever is larger, should be maintained within the rated voltage
range.
Visual inspection
Using calipers
No failure should be observed when a voltage of 250% of the
rated voltage is applied between the both 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 normal temperature
and humidity and within 2 minutes of charging.
The capacitance/D.F. should be measured at reference
temperature at the frequency and voltage shown in the table.

MIL-STD-883 Method 2011 Condition D
Mount the capacitor on a gold metallized alumina substrate with
Au-Sn (80/20) and bond a 25µm (0.001 inch) gold wire to the
capacitor terminal using an ultrasonic ball bond. Then, pull wire.
MIL-STD-883 Method 2019
Mount the capacitor on a gold metallized alumina substrate
with Au-Sn (80/20). Apply the force parallel to the substrate.
Ramp frequency from 10 to 55Hz then return to 10Hz all within
1 minute. Amplitude: 1.5 mm (0.06 inch) max. total excursion.
Apply this motion for a period of 2 hours in each of 3 mutually
perpendicular directions (total 6 hours).
The capacitor should be set for 24±2 hours at room
temperature after one hour of heat treatment at 150+0/–10°C,
then measure for the initial measurement. Fix the capacitor to
the supporting jig in the same manner and under the same
conditions as (11) and conduct the five cycles according to the
temperatures and time shown in the following table. Set it for
24±2 hours at room temperature, then measure.
