FEATURES
This is a power supply circuit for SMD inductors using ferrite materials.
Large current and lower DCR were achieved by the connecting wire-less structure.
Direct current-sensing properties under high temperature conditions are good, too.
Operating temperature range: 40 to +125C (including self-temperature rise)
APPLICATION
Servers, BTS, VRM, others

Rated current: smaller value of either Isat or Itemp.
Isat: When based on the inductance change rate (20% below the nominal value)
Itemp: When based on the temperature increase (temperature increase of 40C by self heating)
