The specifications listed at right shall be met when the
capacitors are restored to 20°Cafter the rated voltage is
applied for 2000 hours (160 to 400V : 3000hours) 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.
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.
