It carries a rated current of 1.4 A and saturates at 1.7 A, making it sized for the output filter of a buck converter or POL regulator drawing up to about 1.2 A continuous with margin. ## DC resistance and thermal budget in the 1008 footprint Maximum DCR is 216 mOhm. ## Shielded construction with iron powder core Shielding contains the magnetic flux, so the inductor can sit adjacent to other magnetic components or a ground plane without coupling noise into nearby traces. The iron powder core material handles the DC bias without the hard saturation knee of ferrite — the inductance rolls off gradually as current approaches 1.7 A Isat, which gives the downstream regulator a softer current-limit response. ## Obsolete — sourcing through independent channels Murata lists this part as obsolete. No official successor order code is recorded. For existing BOM positions, the part is available through independent surplus and broker channels; quantities and pricing are confirmed at RFQ.","metaTitle":"Murata DFE252012R-H-4R7M=P2 4.7 µH Shielded Inductor, 1.4 A","metaDescription":"Obsolete Murata DFE252012R-H-4R7M=P2 drum core wirewound inductor, 4.7 µH ±20%, 1.4 A rated, 216 mOhm DCR, 1008 shielded.
