Parametric fit for a 5.6 µH power rail
The Murata DFEH7030D-5R6M=P3 is a 5.6 µH shielded power inductor in the DFEH7030D series, rated for 3.8 A continuous with a saturation current floor of 5.4 A at 100 kHz test frequency. Its 54 mOhm max DCR sets the copper loss at 0.78 W at full rated current — a figure that factors into the thermal budget for a 7.0 x 6.6 mm footprint. The iron powder core and full shield contain the field, so adjacent passives on a dense automotive ECU layout see less EMI coupling than an unshielded drum core would allow.
Automotive temperature grade and derating
AEC-Q200 qualified and rated from -40°C to 155°C, this inductor is specced for under-hood and engine-bay environments where the ambient sees 125°C and the part's own self-heating pushes the hotspot higher. The ±20% tolerance on 5.6 µH is typical for power-grade ferrite and iron-powder cores — the inductance drop at the saturation current limit (5.4 A) is already baked into the 20% band at 100 kHz. Seated height of 3.00 mm keeps the inductor under a 4-layer board's component-height ceiling for a sealed ECU housing.
NRND lifecycle and sourcing posture
For a production board that already qualifies this inductor, the NRND flag means the supply window is finite; securing inventory through independent distribution against an RFQ is the standard path.
