47 µH, 90 mA — what the ratings mean for fit
The LBC2012T470M: The 47 µH inductance at 2.52 MHz test frequency is paired with a 90 mA continuous current rating. At that current, the 5.8 Ohm DCR drops about 0.52 V and dissipates 47 mW — enough to cause noticeable self-heating in the 0805 body if airflow is restricted. The unshielded drum-core construction means the magnetic field extends beyond the package; keep sensitive traces or other magnetics at least one package width away to avoid coupling. Self-resonant frequency is 11 MHz, so the inductor behaves as an inductor up to roughly that point. Above SRF the impedance becomes capacitive, limiting its use in high-frequency filtering above 10 MHz.
0805 footprint and temperature range
It is a surface-mount drum-core wirewound with a ferrite core, unshielded.
