Item Performance Characteristics
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
5000 hours at 105
°C
, the peak voltage shall not exceed the rated
voltage.
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 reguirements listed at right.
After an application of charge-discharge voltage for 50million times
(charge-discharge voltage difference(ΔV) = rated voltage
×
0.3, cycle 3Hz)
capacitors shall meet the characteristics requirement listed at right.
