Load life with the rated ripple current applied After the capacitors are subjected to DC voltage with the rated ripple current applied for 2,000 hours at the maximum rated operating temperature, the following specifications should be satisfied when the capacitors are restored to 20ÞC

The sum of DC voltage and peak AC voltage must not exceedthe full rated voltage of the capacitor.
Capacitance Change =>+20% of the initial measured value
tan ð =< 200% of the initial specified value
Leakage current =< The initial specified value
Shelf Life The following specifications shall be satisfied when the capacitors are restored to 20ÞC after exposing them at maximum operating temperature for 1,000 hours without voltage applied.

The rate working voltage should 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 the initial measured value
tan ð =< 150% of the initial specified value
Leakage current =< The initial specified value
Others Satisfies characteristics W of JIS C 5141
