The following specifications shall be satisfied when the capacitors are restored to 20 C after
subjecting them to DC voltage for 2,000 hours 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.

Shelf Life
The following specifications shall be satisfied when the capacitors are restored to 20 C after
exposing them for 1,000 hours at 105 C without voltage applied. The rated voltage shall be
applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than
48 hours before the measurements.
