(2) Voltage Applied Method
When the withstanding voltage is applied, the capacitor's
lead or terminal should be firmly connected to the output
of the withstanding voltage test equipment, and then the
voltage should be raised from near zero to the test
voltage.
If the test voltage without the raise from near zero voltage
would be applied directly to capacitor, test voltage should
be applied with the zero cross.* At the end of the test
time, the test voltage should be reduced to near zero,
and then capacitor's lead or terminal should be taken off
the output of the withstanding voltage test equipment.
If the test voltage without the raise from near zero voltage
would be applied directly to capacitor, the surge voltage

may rise, and therefore, a defect may be caused.
*ZERO CROSS is the point where voltage sine wave
passes 0V. See the figure at right.
4. Fail-Safe
When the capacitor is broken, failure may result in a short
circuit. Be sure to provide an appropriate fail-safe
function like a fuse on your product if failure could result
in an electric shock, fire or fuming.
FAILURE TO FOLLOW THE ABOVE CAUTIONS MAY
RESULT, WORST CASE, IN A SHORT CIRCUIT
AND CAUSE FUMING OR PARTIAL DISPERSION
WHEN THE PRODUCT IS USED.
