It delivers 2.2 µH ±20% with a continuous current rating of 2.3 A and a saturation current floor of 3.1 A. The 2.3 A current rating is the DC bias at which the inductance drop stays within the rated tolerance — above that the core begins to saturate, and the inductance rolls off. The 3.1 A saturation current is the hard ceiling where inductance falls by 30% typically, so this part is sized for rails that pull 1.5–2.0 A steady with a 3 A transient headroom. ## DCR and the thermal budget Maximum DC resistance is 97 mOhm. At 2.3 A the I²R loss is about 0.51 W, which the 1008 (2520 Metric) body dissipates into the PCB copper — the 1.00 mm seated height limits the air convection, so the pad footprint and via count under the part matter for keeping the temperature rise below the 125 °C upper operating limit. The iron powder core handles the saturation gracefully — no air-gap fringing, and the flat-wire winding reduces AC resistance at switching frequencies compared to round wire. Tested at 1 MHz, this inductor suits buck converters switching in the 500 kHz to 2 MHz range where the core loss stays manageable. ## Board-fit checklist for the 2520 footprint The shielded construction contains the flux within the core, so adjacent components on a tight layout — 0.5 mm spacing typical — see minimal coupling. ## Sourcing and lifecycle posture Murata lists this as Active — no NRND or EOL notice on file. It is a current-production part, sourced through authorized distribution and independent channels.","metaTitle":"Murata DFE252010F-2R2M=P2 Shielded Power Inductor, 2.2 µH","metaDescription":"Murata DFE252010F-2R2M=P2 drum core wirewound inductor, 2.2 µH, 2.3 A, 97 mOhm DCR, shielded, 1008 package.
