The following specifications shall be satisfied when the capacitors are restored to ؀20؇C after
subjecting them to DC voltage for 5,000 hours at ؀105؇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: ≤ ؓ20% of initial measured value
Tan ␦ ( DF )
: ≤ 200% of initial specified value
Leakage current : ≤ initial specified value
The following specifications shall be satisfied when the capacitors are restored to ؀20؇C after
exposing them for 1,000 hours at ؀105؇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: ≤ ؓ20% of initial measured value
Tan ␦ ( DF )
: ≤ 150% of initial specified value
Leakage current : ≤ initial specified value
