After 2000 hours application of W.V. and +125C ripple current value , the capacitor shall meet
the following limits. ( DC + ripple peak voltage  rated working voltage )
Capacitance Change
 25% of initial.
Dissipation Factor
 200% of initial specified value
Leakage Current
 initial specified value
At +125C no voltage application after 1000 hours, the capacitor shall meet the limits for load life
characteristics. ( with voltage treatment )
