The specifications listed at right shall be met when the
capacitors are restored to 20°C after D.C. bias plus rated
ripple current is applied for 3000 hours at 125°C or 135°C,
the peak voltage shall not exceed the rated voltage.
Endurance
Leakage current
After storing the capacitors under no load at 125˚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.
