The following specifications shall be satisfied when the capacitors are restored to ؀20؇C

after subjecting them to DC voltage for the specified test time at ؀105؇C with the rated ripple

current applied. The sum of the DC voltage and peak AC voltage must not exceed the full

rated voltage of the capacitors.
