Endurance
The specifications listed at right shall be met
when the capacitors are restored to 20°C after
the rated voltage is applied for 2000 hours at
85°C.
Shelf Life
After storing the capacitors under no load at 85°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.
Resistance to soldering
heat
The capacitors are kept on a hot plate for 30 seconds, which is
maintained at 250°C. The capacitors shall meet the
characteristic requirements listed at right when they are
removed from the plate and restored to 20°C.
Marking
Black print on the case top.
