Endurance
After an application of DC voltage (in the range of rated
DC voltage even after over-lapping the specified ripple
current) for 2000 hours at 105°C, capacitors meet
the characteristic requirements listed at right.
Capacitance change Within ±20% of initial value
tan δ
200% or less of initial specified value
Leakage current
Initial specified value or less
Shelf Life
After storing the capacitors under no load at 105°C for 1000
hours, and after performing voltage treatment based on JIS C
5101-4 clause 4.1 at 20°C, they will meet the requirements
listed at right.
Capacitance change Within ±15% of initial value
tan δ
150% or less of initial specified value
