470 nH, 4.4 A — the power rail filtering envelope
The DFE252010F-R47M=P2: Rated for 4.4 A continuous current with a saturation current floor of 6.6 A, this inductor handles the ripple current of a point-of-load buck converter without saturating the iron powder core under transient loads. The 27 mOhm max DCR sets the I²R conduction loss — at 4.4 A the copper loss is about 0.52 W, which the 1008 package dissipates through the PCB copper plane under the part. Inductance is tested at 1 MHz, which matches the typical switching frequency band for DC-DC converters in this current class — the core material's permeability holds stable up through that frequency.
The shielded construction with iron powder core contains the magnetic field within the package — adjacent components on a dense board see minimal flux coupling, which matters for sensitive analog or RF circuitry sharing the same power rail.
