The specifications listed at right shall be
met when the capacitors are restored to
20°C after the rated voltage is applied for
1000 hours at 105°C.
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.
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.
