680 nH shielded power inductor for DC-DC converter rails
The Murata DFE201610P-R68M=P2 is a shielded wirewound drum-core inductor in the DFE201610P series, rated 680 nH ±20% with a continuous current rating of 2.7 A and a saturation current floor of 3.6 A. The 48 mOhm max DCR keeps I²R losses low enough that the part can handle the 2.7 A rating without exceeding the 125°C upper operating limit in a typical 85°C ambient power supply.
Current handling and saturation margin for point-of-load designs
The 2.7 A rated current is the DC bias at which the temperature rise stays within the component's self-heating budget; the 3.6 A saturation current is the DC bias at which inductance drops by 30% — a 33% margin above rated current means the inductor holds its value through load transients typical of processor core rails. Iron powder core material gives the DFE201610P-R68M=P2 a flat inductance-vs-DC-bias curve compared to ferrite alternatives, so the 680 nH value is maintained closer to the saturation knee — useful when the load current peaks above the continuous rating for short durations. The 0806 (2016 metric) footprint with a 1.00 mm seated height fits into low-profile portable device power stages where board-side clearance is under 1.2 mm.
Active production status and procurement posture
No single-source risk — the DFE201610P series has multiple qualified production sites.
