The ferrite core and unshielded construction mean the magnetic field extends beyond the component body — keep adjacent traces and other magnetics at least one package width away to avoid coupling. ## Self-resonant frequency and temperature envelope The self-resonant frequency is 7 MHz, tested at 1 MHz. Above that frequency the inductor behaves capacitively, so this part suits filtering and DC-DC conversion up to a few MHz where the impedance curve is still inductive. The ferrite core's permeability changes with temperature, but the inductance tolerance (±10%) covers the drift across this range. ## Last-buy lifecycle — plan the BOM line Murata has placed the LQH31CN101K03L in Last Buy status. That means the manufacturer has announced end-of-life; the remaining production window is finite. Once that window closes, the part moves to discontinued and only surplus inventory will be available. For a BOM that depends on this exact inductance and footprint, the prudent move is to secure the last-time-buy quantity now or qualify a drop-in alternative while the original is still orderable.","metaTitle":"Murata LQH31CN101K03L 100 µH Inductor, 80 mA, 1206, Last Buy","metaDescription":"Murata LQH31CN101K03L drum core wirewound inductor, 100 µH, 80 mA, 15.6 Ohm DCR, 1206 package.
