47 µH in an 0806 footprint
The Murata LQH2MCN470K02L is a 47 µH drum core wirewound inductor in the LQH2 series, built on a ferrite core and housed in an 0806 (2016 Metric) surface-mount package. Rated for 120 mA continuous current with a maximum DC resistance of 6.63 Ω, this part suits low-power filtering and decoupling roles where board space is tight.
What the ratings mean on the bench
The 47 µH inductance is tested at 1 MHz; the self-resonant frequency of 18 MHz sets the upper bound for effective filtering — above that the part behaves capacitively. A 120 mA current rating at 6.63 Ω DCR means the I²R loss at full load is about 95 mW — fine for signal-line filtering but not for power rail bulk storage where a lower DCR part would be needed. Unshielded construction means the magnetic field extends beyond the core — keep it 2–3 mm away from sensitive analog traces or other magnetics to avoid coupling.
