The 130 mA current rating and 793mOhm max DCR set the conduction loss budget — at full rated current the I²R loss is about 13.4 mW, which is manageable for a 1206 footprint but worth checking against the board's thermal environment. Self-resonant frequency is 38 MHz, and the Q factor is 35 at 8 MHz — this inductor is usable in low-frequency filtering and DC-DC output smoothing up to a few MHz, but the unshielded construction means the flux couples into nearby traces; keep sensitive analog routing at least a few millimeters away. ## Last Buy — what that means for procurement Murata has placed the LQH31MN3R3K03L into Last Buy status — the manufacturer will not replenish stock after the final order window closes. For volume BOM positions already locked to this order code, the procurement strategy should secure the remaining lifetime quantity or qualify a drop-in alternative before the last-buy deadline passes. We source this part through independent distribution — availability and pricing are confirmed at RFQ, not assumed from a static stock figure. Operating temperature range is -40°C to +85°C, which covers most indoor and outdoor equipment but falls short of extended industrial or automotive under-hood grades — plan accordingly if the ambient near the inductor exceeds 85°C.","metaTitle":"LQH31MN3R3K03L Murata 3.3 µH Unshielded Wirewound Inductor","metaDescription":"LQH31MN3R3K03L from Murata Electronics, 3.3 µH ±10% wirewound inductor, 130 mA, 793mOhm DCR, 1206 package.
