Drum core wirewound construction, 150 µH at 95 mA
The Taiyo Yuden LBC2518T151M is a drum core, wirewound inductor built on a ferrite core, delivering 150 µH ±20% at a rated current of 95 mA. The wirewound construction gives it a self-resonant frequency of 7 MHz, above which the part behaves capacitively — a consideration for filter designs operating near that boundary. DC resistance is 6.1 Ohm, producing an I²R conduction loss of roughly 55 mW at the rated current. That loss limits the continuous current in free-air mounting on a standard PCB — thermal rise above ambient must be budgeted into the power dissipation. The unshielded construction means the magnetic field radiates from the core.
Board-fit footprint and reflow assembly
Tape-and-reel or cut-tape packaging options suit both prototyping and production volumes. Operating temperature spans -25°C to 105°C, which covers most indoor and industrial environments but does not meet automotive-grade (AEC-Q200) requirements. The ferrite core material is specified for this temperature band, with inductance stability typical of unshielded ferrite drum cores.
Sourcing is straightforward through authorized distribution and independent channels. No direct second-source cross-reference is recorded, but the 1007 footprint is a standard size carried by multiple manufacturers.
