12 µH in a 1210 footprint
The Murata LQH32MN120J23L is a drum core wirewound inductor from the LQH32 series, delivering 12 µH at 180 mA in a standard 1210 (3225 Metric) surface-mount package. With a DC resistance of 2 Ohm max and a self-resonant frequency of 18 MHz, it's sized for power-supply filtering and decoupling in low-to-moderate current rails where the 180 mA rating sets the load ceiling.
What the ratings mean on the bench
The 180 mA current rating is the DC bias current at which the inductance typically drops by 10% — stay under that for the nominal 12 µH value. The 2 Ohm DCR means a 180 mA load drops 360 mV across the winding, so factor that into the rail budget if the inductor sits in a low-voltage path. The unshielded construction means the magnetic field radiates — keep sensitive traces or other magnetics at least one part-width away on the layout.
Package and placement
The nonstandard case designation just means it's a Murata-specific body outline within the 1210 land pattern; the solder pads follow the usual 1210 IPC footprint. Tape-and-reel packaging (Cut Tape also available) means it feeds into a standard 8 mm pick-and-place carrier. No special moisture sensitivity level is noted, so standard MSL 1 handling applies.
