MINIATURE ALUMINUM ELECTROLYTIC CAPACITORS
MK
High Ripple Current
Series
Low Impedance
Solvent Proof
Ripple current compared with LK series
Enabled high ripple current by a reduction of impedance at high frequency
High reliability withstanding 5000 hours load life at 105 C
(2000 ~ 3000 hours for smaller case sizes as specified below)
Complied to the RoHS directive
