FEATURES
Magnetic shield type wound inductor for power circuits using a metallic magnetic material.
Compared to ferrite wound type inductors, it is possible to achieve large current, low Rdc, and compactness.
Low inductance variance in high-temperature environments with good DC superimposition characteristics.
Metallic magnetic material is used, and the structure has an integrated molded coil, so hum noise is lower than with core adhesive coils.
APPLICATION
Note PCs, HDDs, servers, VRMs, compact power supply modules, other

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