Characteristics
-25 ~ +105 C
20% at 120Hz, 20 C
I=3 CV ( A) (after 5 minutes)
0.15 max. at 120Hz, 20 C
After an application of DC bias voltage plus the rated AC ripple current for 2000 hours at 105 C
The measurement shall meet the following limits.
Leakage current
Less than specified value
Capacitance change
Within 20% of initial value
tan
Less than 200% of specified value
After 1000 hours no load test, leakage current, capacitance and tan are same as load life value.
The measurement shall be performed at 20 C by the KS C 6503 clause 5.1.
The pressure relief vent will operate in normal conditions, with no dangerous conditions such as
flames, ignitions or dispersion of peaces of the capacitor and/or case
