Wirewound 220 µH in a 1007 footprint
The LBC2518T221KV is a 220 µH wirewound inductor from Taiyo Yuden's LB, C Type series, unshielded, in a 1007 (2518 Metric) surface-mount package. Rated for 80 mA continuous current with a maximum DC resistance of 10.92 Ohm — the DCR dominates the I²R loss at this inductance value, so the 80 mA ceiling is set by the winding temperature rise, not the magnetic core. Self-resonant frequency is 5.5 MHz, tested at 796 kHz; above that frequency the inductor behaves capacitively and loses its inductive impedance.
NRND — sourcing posture
Taiyo Yuden lists this part as Not Recommended for New Designs (NRND) — it remains available for existing BOM positions but is not intended for new product introductions. For a replacement, parametric matching (same 220 µH, 80 mA, 1007 footprint, unshielded) is the route; a board spin may be needed if the DCR or self-resonant frequency must be identical.
