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.
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.
