Load life
After an application of DC bias voltage plus the rated AC ripple current for 3000 hours at 125 C
( 10 : 2000 hours). The measurement shall meet the following limits.
Less than specified value
Leakage current
Within 20% of initial value
Capacitance change
Less than 200% of specified value
tan
After 1000 hours no load test, leakage current, capacitance and tan are same as load life value.
The measurement shall be performed after exposure for 24 hours at room temperature after
application of DC rated voltage to the capacitors for 30 minutes.
