SPM-HZ series (for automotive)
AEC-Q200
SPM10054-HZ type
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. 40 to 125C (including self-tempera-
ture rise)
Metallic magnetic material is used, and the structure has an integrated molded coil, so hum noise is lower than with ferrite core adhesive coils.
Compliant with AEC-Q200
APPLICATION
Automotive-related equipment (Car navigation, car audio, electronic power steering, headlights, other)
Application guides: Automotive (xEV), Car Infotainment

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)
