The saturation current of 2.8 A is the hard ceiling where inductance falls off sharply; a short-circuit or inrush event that pushes current past 2.8 A will cause the inductor to act like a short until the fault clears. ## Shielded construction and core material for EMI-sensitive circuits The iron-powder core with flat-wire winding and full magnetic shielding contains the flux within the package — this keeps the inductor from coupling switching noise into nearby traces or sensitive analog circuits on the same board. Flat-wire construction also reduces AC winding losses at higher switching frequencies compared to round-wire windings of the same cross-section. Reflow profile follows standard lead-free soldering with a peak temperature of 260°C — the iron-powder core handles the thermal shock without cracking, unlike some ferrite-core inductors. ## Lifecycle and supply posture The part carries full RoHS compliance documentation and AEC-Q200 test reports from the manufacturer.","metaTitle":"Murata DFE252012PD-2R2M=P2 Shielded Power Inductor, 2.2 µH","metaDescription":"Murata DFE252012PD-2R2M=P2 shielded wirewound inductor, 2.2 µH ±20%, 2.2 A rated, 2.8 A Isat, AEC-Q200 qualified.
