Unshielded construction means the magnetic field extends beyond the component body — keep sensitive traces or other magnetics at least a part-width away on the layout to avoid coupling. ## Q factor and self-resonant frequency Q factor is 40 at 2.5 MHz, and the self-resonant frequency sits at 14 MHz. Above that frequency the inductor behaves capacitively — the 22 µH rating holds only below SRF, so filter designs should stay well under 14 MHz. Operating temperature range is -40°C to 85°C, which covers most indoor and automotive-cabin environments but not under-hood or high-temp industrial zones. ## Last Buy — sourcing window is open Murata has marked the LQH31MN220K03L as Last Buy. This means the manufacturer has announced end-of-life and is accepting final orders — once that window closes, the only source will be surplus or broker inventory. For a BOM that already qualifies this inductor, now is the time to secure lifetime buy quantities or identify a drop-in replacement. No official successor is listed in Murata's LQH31 family.","metaTitle":"Murata LQH31MN220K03L 22 µH Wirewound Inductor, 85 mA","metaDescription":"Murata LQH31MN220K03L 22 µH wirewound inductor, 85 mA, 4.03 Ohm DCR, 1206 package.
