Shelf Life The following specifications shall be satisfied when the capacitors are restored to
20C after
exposing them for 1,000 hours at
85C 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.
Dissipation Factor (Tan )At
20C, 120Hz
When nominal capacitance exceeds 1,000F, add 0.02 to the values above for each 1,000F increase.
