What the 2.2 µH and 7.1 A ratings mean for your power rail
The DFEG7030D-2R2M=P3 is a 2.2 µH shielded power inductor from Murata's DFEG7030D series, rated for 7.1 A continuous DC current with a saturation floor of 9.2 A — the point where the iron-powder core loses inductance and the rail starts to droop. The 18 mOhm max DCR translates to about 0.9 W of I²R loss at full rated current — a figure that drives the copper-fill area on the PCB and the airflow budget in a sealed enclosure.
NRND — what it means for your BOM line
For a prototype or a repair run, the part is still orderable; for a fresh layout, a designer would typically look at the active DFEG7030D variants or the next-generation DFEG series with the same 7.00 mm x 6.60 mm footprint.
Board-fit and soldering note
The nonstandard 7.00 mm x 6.60 mm body with a 3.00 mm seated height is a common power-inductor footprint — the pad layout matches many 7030-size parts from other manufacturers, so a second-source swap is feasible without a board spin. Shielded construction with an iron-powder core means the inductor radiates less magnetic field into nearby sense traces or RF sections than an unshielded drum core would.
