Rated for 100 mA continuous current, the inductor's 3.25 Ohm max DCR means I²R loss hits roughly 32 mW at full load — a figure that stays within the 1206 package's thermal budget at 85°C ambient. The 20 MHz self-resonant frequency sets the usable band: above that, the parasitic capacitance between windings dominates and the component behaves capacitively, not inductively. ## Last Buy — the sourcing window is closing Murata has flagged the LQH31MN100J03L as Last Buy — the manufacturer is no longer accepting ongoing production orders, and remaining stock is finite. For a BOM that depends on this exact 10 µH value in the 1206 footprint, the Last Buy status means procurement should lock in the required quantity now. Once the pipeline dries, the only channel is surplus or broker inventory. Any replacement will require requalifying a different inductor — same inductance, same package, but different DCR or current rating. ## 1206 footprint — board-fit checklist Unshielded construction means the magnetic field radiates into the surrounding PCB area; keep sensitive analog traces or other magnetics at least one package width away to avoid coupling.","metaTitle":"Murata LQH31MN100J03L 10 µH Inductor, 100 mA, 1206, Last Buy","metaDescription":"Murata LQH31MN100J03L drum core wirewound inductor, 10 µH ±5%, 100 mA, 3.25 Ohm DCR, 1206 package.
