Parametric fit for a 2.2 µH rail
The Murata DFE201610R-H-2R2M=P2 is a shielded drum-core wirewound inductor in the DFE201610R series, rated 2.2 µH ±20% with a continuous current rating of 1.4 A and a saturation current floor of 2 A. The 168 mOhm max DCR sets the I²R conduction loss — at 1.4 A the copper loss alone is about 330 mW, which the 0806 body dissipates into the board copper without exceeding the 125 °C rated ceiling.
Board-fit and construction details
The iron-powder core and full magnetic shield mean the inductor's stray field does not couple into adjacent traces or components, a consideration when the inductor sits near a sensitive analog front-end or a PLL loop filter.
