Load Life
After 2000 hours application of W.V. and +105°C ripple current value , the capacitor shall meet
the following limits. ( DC + ripple peak voltage ≤ rated working voltage )
Capacitance Change ≤ ±20% of initial.
Dissipation Factor ≤ 200% of initial specified value
Leakage Current
≤ initial specified value
Shelf Life
At +105°C no voltage application after 1000 hours the capacitor shall meet the limits for load life
characteristics. ( with voltage treatment )
