Parametric fit and core material
The DFE252010R-H-1R0M=P2 is a 1 µH shielded wirewound inductor in the DFE252010R series, rated for 2.7 A continuous with a saturation current of 3 A. The iron powder core gives it a soft saturation characteristic — inductance rolls off gradually past Isat rather than collapsing abruptly, which matters for DC-DC converter loops where the inductor sees transient current spikes above the rated average. The 68 mOhm max DCR sets the I²R loss at full load: at 2.7 A the copper loss is roughly 0.5 W, which the 1008 package must dissipate through the board copper. The low profile (1.0 mm seated height) and 2.5 × 2.0 mm footprint suit it for space-constrained POL regulators on portable or embedded boards.
When sourcing an obsolete shielded 1 µH inductor in the 1008 footprint, the key parametrics to match are the 2.7 A current rating, 3 A saturation floor, and 68 mOhm DCR ceiling.
