68 µH, 140 mA — where this unshielded drum core fits
The Taiyo Yuden LBC2518T680M is a 68 µH unshielded wirewound inductor in the LB, C Type series, built on a ferrite drum core. 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.
