INDUCTORS

Inductors for power circuits

Wound metal

SPM-DZ series (for automobiles)

SPM4020-DZ type

FEATURES

Metal composite type wound inductor for power circuits using a metallic magnetic material.

Compared to ferrite wound type inductors, low Rdc and miniaturization can be realized due to superior DC superimposition characteris-

tics of metallic magnetic materials.

Operating temperature range: –55 to +155°C (including self-temperature rise)

Compliant with AEC-Q200

APPLICATION

Automotive-related equipment (ADAS, ECM, BCM)

PART NUMBER CONSTRUCTION

CHARACTERISTICS SPECIFICATION TABLE

Isat: Based on the rate of change from the initial value of the inductance with DC current

Itemp: Based on self-temperature rise due to DC current (rated current)
