Datasheet

Low impedance compared with WL series
Enabled high ripple current by a reduction of impedance at high frequency
High reliability withstanding 5000 hours load life at 105 C
(2000 ~ 4000 hours for smaller case sizes as specified below)
For switching power supplies, noise filter, adaptor, charger
