Rated for 140 mA continuous current with a DC resistance of 2.8 Ohm, this part suits low-to-medium current rails in DC-DC converters, input/output filters, and noise suppression circuits where the DCR-induced voltage drop and I²R loss are acceptable at the rated load. The unshielded construction means the magnetic field radiates beyond the core — board placement should keep sensitive traces or adjacent magnetics at a distance to avoid coupling. ## Frequency ceiling and temperature envelope Self-resonant frequency is 9.5 MHz — above this point the inductor behaves capacitively, so the switching frequency of the converter should stay well below that ceiling to maintain inductive impedance. Operating temperature spans -25°C to 105°C, covering most indoor and industrial ambient ranges but not extended automotive or high-temp environments. Inductance is tested at 2.52 MHz with ±10% tolerance, meaning the actual value at DC or at the circuit's operating frequency will shift — account for the tolerance band in the filter cutoff or ripple current calculation. ## Active production — stable supply for BOM planning Supplied in tape-and-reel packaging for automated pick-and-place assembly, consistent with high-volume SMT lines.","metaTitle":"Taiyo Yuden LBC2518T680K 68µH Wirewound Inductor, 140mA","metaDescription":"Taiyo Yuden LBC2518T680K, 68 µH ±10% wirewound inductor, 140 mA rated current, 2.8 Ohm DCR, 1007 package.
