That inductance-current combination slots it into low-power DC-DC converter output filters, signal-line chokes, and noise suppression where the load stays under 200 mA and the board can tolerate an unshielded magnetic field. ## Self-resonant frequency and Q — the frequency ceiling Self-resonant frequency is 9.3 MHz, meaning above that the part looks capacitive. For a switching regulator switching at 1–2 MHz, the inductor still behaves inductively with margin. The Q factor is 35 at 1 MHz — moderate for a wirewound drum core; adequate for general-purpose filtering but not for narrowband tuned circuits where a higher-Q ferrite or air-core would be needed. ## Unshielded — placement matters This is an unshielded inductor. The magnetic flux radiates from the drum core, so keep it away from sensitive analog traces, other magnetics, or RF sections on the same layer. In a mixed-signal board, a shielded inductor would contain the field — here the layout has to do the work. ## 1812 footprint — field-swappable with tweezers The large rectangular terminations make it easy to hand-place and rework with a soldering iron and tweezers, no hot-air station required. That is a plus for field repairs or prototype spins. ## Active lifecycle — no rush to redesign Murata lists this part as Active.","metaTitle":"Murata LQH43MN560J03L 56 µH Unshielded Inductor, 200 mA","metaDescription":"Murata LQH43MN560J03L wirewound drum-core inductor, 56 µH ±5%, 200 mA, 1.7 Ohm DCR, 9.3 MHz SRF, 1812 SMD.
