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 85 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.
Capacitance change:

Shelf Life
The following specifications shall be satisfied when the capacitors are restored to 20 C after
exposing them for 1,000 hours at 85 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.
