The following specifications shall be satisfied when the capacitors are restored to ؀25؇C
after subjecting them to the DC rated voltage for 2,000 hours at ؀150؇C with the rated ripple
current applied. The sum of the DC voltage and peak AC voltage must not exceed the full
rated voltage of the capacitors.
Capacitance change: ≤ 15% from initial measurement
ESR change
: ≤ 200% of initial specified limit
Impedance change : ≤ 200% of initial specified limit
Leakage current : ≤ initial specified limit
The following specifications shall be satisfied when the capacitors are restored to ؀25؇C after
exposing them for 1,000 hours at ؀150؇C without voltage applied. The rated voltage shall be
applied to the capacitors for a minimum of 30 minutes, at least 24 hours and not more than
48 hours before the measurements.
Capacitance change: ≤ 10% from initial measurement
ESR change
: ≤ 150% of initial specified limit
Leakage current : ≤ initial specified limit
