Core construction and the 62 MHz ceiling
The LQH43MN2R2M03L is a drum-core, wirewound inductor on a ferrite core — unshielded, so stray field couples into adjacent traces if the layout crowds the magnetic path. The self-resonant frequency of 62 MHz sets the usable ceiling: above that the inductance rolls off and the part behaves capacitively. For a 2.2 µH value, that SRF is typical of a wirewound in this footprint; a multilayer ceramic would push SRF higher but saturate at a fraction of the current. Rated 500 mA continuous with a maximum DC resistance of 300 mOhm. At full rated current the I²R loss is 75 mW — negligible in free air but worth a quick thermal check if the inductor sits next to a hot regulator or in a 85°C ambient. The ferrite core saturates gradually; the 500 mA figure is the heating limit, not the saturation knee.
1812 footprint and board-fit note
The unshielded construction means the inductor radiates a fringe field; keep sensitive analog traces or high-impedance nodes at least one package width away. The ferrite core material is standard for this inductance and frequency band; no special handling beyond normal SMT reflow.
