Endurance
The specifications listed at right shall be met when the
capacitors are restored to 20˚C after D.C. bias plus rated ripple current is applied for 8000 hours (2000 hours for φD=4, 5 and 6.3, 3000 hours for φD=8, 5000 hours for φD=10, 7000 hours for φD=12.5) at 105˚C, the peak voltage shall not exceed the rated voltage.
Capacitance change Within ±20% of the initial capacitance value
tan δ
200% or less than the initial specified value
Leakage current
Less than or equal to the initial specified value
Shelf Life
After storing the capacitors under no load at 105˚C for 1000 hours and then performing voltage treatment based on JIS C 5101-4 clause 4.1 at 20°C, they shall meet the specified values for the endurance characteristics listed above.
