Rated for 140 mA continuous current with a 2.8 Ohm DC resistance, it is sized for low-power filtering and DC-DC converter output stages where the load current stays under 140 mA and the DCR drop is acceptable. ## NRND — plan the BOM migration now This means the part remains available for existing production runs but is no longer intended for new board spins. ## Temperature range and reflow reality The operating temperature range is -25°C to 105°C, which covers most indoor and industrial ambient conditions but not extended automotive or under-hood environments. The 1007 (2518 Metric) package is a standard two-pad footprint — no tombstoning risk with a typical reflow profile. Tape-and-reel packaging feeds directly into pick-and-place; no special bake is required for this part's moisture sensitivity level, though the reel label should be checked before the oven.","metaTitle":"Taiyo Yuden LBC2518T680M 68 µH Unshielded Inductor, 140 mA","metaDescription":"Taiyo Yuden LBC2518T680M 68 µH unshielded wirewound inductor, 140 mA rated current, 2.8 Ohm DCR, NRND status.
