The 220 mA current rating and 1.7 Ohm max DCR set the DC loss and saturation floor — at full rated current, the resistive drop is 0.37 V, which matters for low-voltage rails where every millivolt counts. The self-resonant frequency of 8.4 MHz means it behaves as an inductor well below that point, making it a fit for switching regulators switching in the hundreds of kHz range or for LC filtering up to a few MHz. ## Rework and board-fit: the 1812 package under the hot air The 1812 body (4.50 mm x 3.20 mm, seated height 2.80 mm) is a two-terminal ferrite-core drum — no exposed pad, no thermal relief needed beyond the standard footprint. The unshielded construction means the magnetic field fringes into the board; keep sensitive traces or other magnetics at least one part-width away to avoid coupling.","metaTitle":"Murata LQH43CN680K03L 68 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH43CN680K03L 68 µH ±10% wirewound inductor, 220 mA, 1.7 Ohm DCR, 1812 SMD, active production.
