Rated for 1.4 A continuous with a saturation current floor of 2 A, the part provides headroom for transient loads — the inductor will not saturate until the peak current exceeds 2 A, which is the point where inductance drops sharply. The 200 mOhm maximum DCR sets the I²R conduction loss at 0.4 W at full rated current, a figure the 1008 (2520 metric) package can dissipate in still air with reasonable PCB copper. The shielded construction contains the magnetic field within the core, reducing radiated EMI into adjacent traces and components. Listed as Active in production by Murata.","metaTitle":"Murata DFE252012P-4R7M=P2 Shielded Power Inductor, 4.7 µH","metaDescription":"Murata DFE252012P-4R7M=P2 shielded wirewound inductor, 4.7 µH ±20%, 1.4 A rated, 2 A saturation.
