The specifications listed at right shall be met
when the capacitors are restored to 20°C
after the rated voltage is applied for 7000
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.
