This combination suits it for signal-line filtering, DC-DC converter output smoothing at low load, or decoupling in circuits where the current draw stays under the 100 mA ceiling. ## Unshielded drum-core construction — layout considerations Built on a ferrite core with an unshielded drum-core winding, this inductor does not contain a magnetic shield. The unshielded construction means the external magnetic field extends beyond the component body — adjacent traces or other magnetics on the board should be spaced to avoid coupling. The self-resonant frequency is 20 MHz, and the Q factor is 35 at 5 MHz, giving a usable range up to the low tens of MHz for tuned or filter applications. ## Last Buy — final order window open Murata has classified the LQH31MN100K03L as Last Buy. This is the final opportunity to secure stock before production ceases. For new designs or long-term BOM stability, evaluate a current-production 10 µH shielded or unshielded inductor in the same 1206 footprint as a replacement path. ## 1206 SMT — footprint and temperature envelope Available on tape and reel for volume production.","metaTitle":"Murata LQH31MN100K03L 10 µH Unshielded Inductor, 100 mA","metaDescription":"Murata LQH31MN100K03L 10 µH wirewound inductor, 100 mA, 3.25 Ohm DCR, 1206 SMT.
