The 85 mA rating is the saturation or thermal limit — for a 27 µH part in a 1206 footprint, the DCR is the dominant loss term at this current, so the voltage drop across the inductor at full load is roughly 0.38 V. That matters when the downstream rail has tight tolerance. ## 1206 footprint and unshielded construction Unshielded construction means the magnetic field radiates — keep sensitive traces or other inductors at least one part-width away to avoid coupling. The ferrite core material is standard for this inductance range and gives a self-resonant frequency of 13 MHz; above that the part behaves capacitively. ## Active production, reel supply Supplied on tape & reel — the reel quantity is the standard MOQ for this series. No second-source or pin-compatible alternative is documented from Murata, but the 1206 footprint is common across multiple vendors if a BOM hedge is needed.","metaTitle":"Murata LQH31MN270K03L 27 µH Unshielded Inductor, 85 mA","metaDescription":"Murata LQH31MN270K03L drum core wirewound inductor, 27 µH ±10%, 85 mA, 4.42 Ohm DCR, 1206 SMD.
