The Taiyo Yuden LBC2518T151K is a 150 µH wirewound inductor in the LB, C Type series, packaged for surface mount in a 1007 (2518 Metric) footprint. Its unshielded construction means the magnetic field radiates outside the core — a consideration when placing it near sensitive traces or other magnetics on the board.
This is the official lifecycle signal that the part is still available for existing production but is not intended for new board spins. For a BOM already qualified with this inductor, the NRND status means the supply window is finite — plan for a last-time-buy or identify a drop-in alternative before the transition to full EOL.
Parametric fit for a power rail
Rated for 95 mA continuous current with a DC resistance of 6.1 Ohm, this inductor suits low-current filtering or energy storage in a DC-DC converter output stage where the load stays under 100 mA. The self-resonant frequency of 7 MHz and test frequency of 796 kHz place it in the range for switching regulators switching in the hundreds of kHz to low MHz band — the inductance holds up until the SRF, above which the component behaves capacitively. Operating temperature spans -25°C to 105°C, covering most indoor and industrial enclosure environments but not extended automotive under-hood duty. The unshielded construction keeps the part cost lower than a shielded equivalent, but the radiated field may couple into adjacent traces — layout separation or a ground plane under the inductor mitigates this.
Package and placement
Tolerance is ±10% on the 150 µH nominal value.
