Parametric profile and fit
The DFEG7030D-4R7M=P3 is a shielded power inductor from Murata's DFEG7030D series, wound on an iron powder core. It delivers 4.7 µH ±20% inductance with a continuous current rating of 4.2 A and a saturation current floor of 5.6 A — the saturation point sits above the rated current, so the inductance holds flat across the full operating range up to 4.2 A. DC resistance is 41 mΩ max, which sets the I²R conduction loss at full load to about 0.72 W — within the thermal budget of the 7.00 mm × 6.60 mm × 3.00 mm surface-mount package. The iron powder core keeps core losses low at switching frequencies typical of automotive DC-DC converters.
This means the part remains available for existing production but is not intended for new BOM entries — a last-time-buy window may apply. No official successor order code is recorded in the lifecycle data. For existing designs that already qualify this inductor, sourcing is available through independent distribution channels.
