1 µH, 1.8 A — the parametric anchor
The DFE18SBN1R0ME0L is a 1 µH ±20% shielded wirewound inductor from Murata's DFE18SBN series, rated for 1.8 A continuous current with a saturation current floor of 1.9 A.
Shielded metal-core construction
The metal composite core and full magnetic shield contain the flux within the package — adjacent traces on a dense 0603 layout see minimal eddy-current coupling, which matters when the inductor shares a 1.6 mm x 0.8 mm footprint with a switching regulator's input capacitor. The 1.9 A saturation current is specified at the inductance-drop threshold; below 1.9 A the core retains its nominal 1 µH value, so the inductor supports the full 1.8 A rated current without entering hard saturation.
Active — no LTB clock ticking
The 0603 footprint and 1 µH / 1.8 A rating are standard enough that a second-source cross-reference exists within the same package class if a BOM hedge is needed.
