The Murata DFE201610E-2R2M=P2 is a 2.2 µH shielded power inductor in the DFE201610E series, built with a metal core that handles 1.7 A continuous and saturates at 2.4 A — the saturation current is the hard ceiling where inductance drops off, so the 1.7 A rated current is the figure to size the DC-DC converter's output filter for continuous operation.
The saturation current (Isat) is 2.4 A — this is the current at which the inductance drops by a specified percentage (typically 30% for power inductors). For a buck converter output filter, the peak inductor current must stay below this value to maintain regulation; the 1.7 A rated current is the continuous DC level, while the 2.4 A saturation ceiling handles transient load steps.
