After applying rated voltage for 1000 hours at 85℃,
the capacitor shall meet the following requirement.
Capacitance Change
Within±20% of the initial value
Dissipation Factor
Not more than 200% of the specified value
Leakage Current
Not more than the specified value
After placed at 85℃without voltage applied for 500 hours,
the capacitor shall meet the same requirement as load life.
