What this 2.2 µH shielded wirewound is for
The Murata LQH2HPN2R2MM0L is a 2.2 µH shielded wirewound inductor in the LQH2 series, housed in a 1008 (2520 Metric) surface-mount package. Its 1.25 A current rating and 176 mOhm max DCR suit it for DC-DC converter output filtering and power rail smoothing in portable or space-constrained designs.
Murata lists this part as Obsolete. The 1008 footprint and 2.2 µH value are common enough that a parametric search for a shielded 2.2 µH inductor in the same package may turn up an active alternative, but there is no pin-compatible drop-in from Murata's current catalog.
Inductance is 2.2 µH tested at 1 MHz. The self-resonant frequency of 10 MHz means the inductor behaves as an inductor well below that point — above it, parasitic capacitance dominates, so keep the switching frequency of your converter under a few MHz to stay in the inductive region. Rated current is 1.25 A with a max DCR of 176 mOhm. At full rated current, the DC loss is roughly 275 mW — check the temperature rise in your board's airflow. Shielding reduces radiated EMI into nearby traces or components — relevant when the inductor sits close to a sensitive analog or RF section on the board.
