Power rail filtering with a 4.7 µH shielded inductor
The Murata DFE201610E-4R7M=P2 is a 4.7 µH shielded wirewound inductor in the 0806 (2016 Metric) footprint, rated for 1.1 A continuous with a saturation current of 1.6 A. This combination suits it for DC-DC converter output filters and input pi-filters where the inductor must handle the full load current without saturating and radiate minimal flux into nearby traces or components.
DCR, saturation margin, and thermal budget
The 288 mOhm maximum DC resistance sets the I²R conduction loss — at 1.1 A the self-heating is roughly 350 mW, which the metal-core construction and 125°C rating absorb without derating the current below the ambient ceiling. The 1.6 A saturation current provides 45% headroom above the rated current, so the inductance holds stable through load transients up to that peak.
0806 footprint and 1.0 mm profile for dense boards
The surface-mount 0806 pad layout is standard; the shielded metal core means the inductor can be placed near sensitive analog or RF circuitry without coupling noise into adjacent traces.
