Withstanding 2000 hours application of rated ripple current of 105
°C
.
Extended voltage range at 200V, 220V and 400V.
Smaller case sizes and higher ripple current than LAK.
Improved safety features for abnormally excessive voltage.
Ideally suited for the equipment used at voltage fluctuating area.
Compliant to the RoHS directive (2011/65/EU).

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 2000 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 requirements listed at right.
