The ferrite core and unshielded construction keep the self-resonant frequency at 75 MHz, so it works for DC-DC converter switching frequencies up to a few megahertz before parasitic capacitance starts to roll off the impedance. ## 1812 footprint and board-fit The surface-mount terminations are compatible with reflow soldering; the tape-and-reel packaging suits automated pick-and-place for volume assembly. Q factor is specified at 20 @ 1 MHz — a moderate value typical for ferrite-core wirewound inductors in this inductance range. The unshielded construction means the stray field may couple into adjacent traces or components; layout should keep sensitive signal routing clear of the inductor's magnetic axis.","metaTitle":"Murata LQH43NH1R8J03L 1.8µH Wirewound Inductor, 1.05A","metaDescription":"Murata LQH43NH1R8J03L drum core wirewound inductor, 1.8 µH ±5%, 1.05 A, 51.6 mOhm DCR, AEC-Q200, 1812 SMD.
