Load life
After an application of DC bias voltage plus the rated AC ripple current for 10000 hours at 105 C.
The measurement shall meet the following limits. The DC voltage plus the peak AC voltage
combined must not exceed the rated voltage.
Less than specified value
Leakage current
Within 20% of initial value
Capacitance change
