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.

4. Test Condition for AC Withstanding Voltage

(1) Test Equipment

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.

*ZERO CROSS is the point where voltage sine wave

passes 0V.

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.

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.

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.
