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 5000 hours (3000
hours for
φD=8,
4000 hours for
φD=10)
at 105˚C, the
peak voltage shall not exceed the rated voltage.
Within ± 20% of the initial capacitance value (6.3V, 10V : ± 30%)
200% or less than the initial specified value (6.3V, 10V : 300%)
Less than or equal to the initial specified value
Shelf Life
Marking
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.
