NRND — what it means for your BOM line
The LBC2518T150M: That means the manufacturer still supports existing production runs, but the part is on a known end-of-life trajectory.
15 µH, 285 mA — the fit decision
15 µH ±20% at 2.52 MHz test frequency, rated for 285 mA continuous with a DCR of 650 mOhm. The 650 mOhm DCR translates to about 53 mW of copper loss at full rated current; in a 1007 package that heat must dissipate through the board copper, not free air. Unshielded drum core construction with a ferrite core — the open magnetic path means the inductor radiates a fringe field. Keep sensitive analog or RF traces at least one package width away to avoid coupling. The self-resonant frequency is 23 MHz; above that the part behaves capacitively and loses its inductive impedance.
1007 (2518 metric) surface-mount footprint, 2.50 mm x 1.80 mm body, 2.00 mm seated height. Tape-and-reel packaging for automated pick-and-place.
