3. Fail-safe
Failure of a capacitor may result in a short circuit. Be sure
to provide an appropriate fail-safe function such as a fuse
on your product to help eliminate possible electric shock,
fire, or fumes.
FUSE
AC IN
Please consider using fuses on each AC line if the
capacitors are used between the AC input lines and earth
(line bypass capacitors), to prepare for the worst case,
such as a short circuit.
4. Test Condition for AC Withstanding Voltage
(1) Test Equipment
Tests for AC withstanding voltage should be made with
equipment capable of creating a wave similar to a
50/60 Hz sine wave.
If the distorted sine wave or overload exceeding the
specified voltage value is applied, a defect may be
caused.
(2) Voltage Applied Method
The capacitor's leads or terminals 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 is applied
directly to the capacitor without raising it from near zero,
it 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 the capacitor's leads or terminals should be
taken off the output of the withstanding voltage test
equipment. If the test voltage is applied directly to the
capacitor without raising it from near zero, surge voltage
may occur and cause a defect.
Voltage sine wave
*ZERO CROSS is the point where voltage sine wave
passes 0V.
0V

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.
