Rated at 1 A with a saturation current of 1.6 A, the 4.7 µH inductance holds up under the ripple current of a buck converter output stage — the 340 mOhm max DCR sets the copper loss floor for the thermal budget. The 1008 (2520 metric) footprint and 0.80 mm seated height fit tight PCB stack-ups where a taller winding would block a backside component or a chassis wall. ## Current handling and saturation margin Shielding contains the magnetic flux within the core, which keeps the inductor from coupling noise into adjacent traces or a nearby RF front-end — important when the inductor sits close to a sensitive analog rail. Flat-wire construction reduces the DC resistance per volume compared to round wire, so the 340 mOhm DCR is the figure to use for I²R loss calculation in the power-stage efficiency model. ## Package and board integration Supplied on tape and reel in both cut-tape and full-reel quantities, so it feeds into a standard pick-and-place line without a feeder change.","metaTitle":"Murata DFE252008U-4R7M=P2 Shielded Power Inductor, 4.7 µH","metaDescription":"Murata DFE252008U-4R7M=P2 shielded wirewound inductor, 4.7 µH ±20%, 1 A rated, 1.6 A saturation, 340 mOhm DCR.
