Its 125 mA current rating is the continuous DC current at which the temperature rise stays within the part's limits — but the real constraint for a BOM engineer is the 4.81 Ohm max DCR. At 125 mA, copper loss is I²R = 0.125² × 4.81 ≈ 75 mW, which is manageable in the 1007 package; at lower currents the loss drops proportionally, so the DCR figure is the one to budget against the thermal environment. Unshielded construction means the magnetic field is not contained within a ferrite shield — keep this inductor at least a few millimetres from sensitive analog traces, other magnetics, or low-level signal paths to avoid coupling. The self-resonant frequency of 9 MHz marks the upper bound for inductive behaviour; above that the parasitic winding capacitance dominates and the part looks capacitive. For typical DC-DC converter or filter applications, stay well below 9 MHz. ## Industrial temperature range and surface-mount footprint The supplier device package is the same 1007 (2518 Metric) footprint, so no extra land-pattern guesswork. Inductance is tested at 796 kHz, a common test frequency for power inductors in this range. The ±10% tolerance is standard for general-purpose filtering and energy storage; if your design requires tighter inductance tolerance (e.g. for resonant circuits), consider a ±5% or ±2% grade. Taiyo Yuden lists the LBC2518T101KV as Active.","metaTitle":"Taiyo Yuden LBC2518T101KV 100 µH Wirewound Inductor, 125 mA","metaDescription":"Taiyo Yuden LBC2518T101KV wirewound inductor, 100 µH ±10%, 125 mA, 4.81 Ohm DCR, unshielded, 1007 (2518 Metric) package.

This sets the copper loss (I²R) at the rated current — at 125 mA the loss is about 75 mW, which the 1007 package can dissipate without exceeding the temperature rating.
