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. Before the measurement, the capacitor shall be preconditioned by applying voltage according to Item 4.1 of JIS C 5101-4.

The endurance of capacitors is reduced with internal heating produced by ripple current at the rate of halving the lifetime with every 5C rise.
When long life performance is required in actual use, the rms ripple current has to be reduced.
