10 µH, 900 mA — the fit boundaries
The LQH32PH100MNCL: Rated 10 µH at 1 MHz test frequency with ±20% tolerance — the inductance tolerance is wide enough that a DC-DC converter's feedback loop must accommodate the full ±20% spread without stability shift. 900 mA continuous current rating with a 1 A saturation floor means the inductor can handle a 10 % overload above rated current before the inductance rolls off — useful headroom for transient load steps in a buck converter output stage. 354 mOhm maximum DCR sets the copper-loss floor: at 900 mA the I²R loss is 0.287 W, which the 1210 body must dissipate without exceeding the 85°C ambient ceiling. For a 12 V-to-3.3 V buck at 900 mA the inductor loss is roughly 3 % of the output power — acceptable for most automotive and industrial rails.
Shielded ferrite, 1210 footprint
Shielded ferrite core construction contains the magnetic flux within the package — adjacent traces on a dense PCB see less coupled noise than an unshielded drum core would radiate. The 30 MHz self-resonant frequency means the inductor looks inductive up through the switching harmonics of a 2-3 MHz DC-DC converter; above 30 MHz parasitic capacitance dominates and the impedance drops.
