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.

Capacitance change:

≤ 20% of initial measured value

Tan

(DF)

:

≤ 150% of initial specified value

Leakage current

≤ initial specified value

Endurance

(Load Life)

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.
