The ferrite core and wirewound construction deliver a Q factor of 40 at 796 kHz and a self-resonant frequency of 4.5 MHz, which sets the usable band for the inductor — above that frequency the component behaves capacitively. ## Package and sourcing posture The base product number LQH43NN allows cross-referencing within the same family for alternate inductance values or tolerances when the BOM requires a variant.","metaTitle":"Murata LQH43NN221K03L Inductor, 220 µH, 110 mA, 1812","metaDescription":"Murata LQH43NN221K03L drum core wirewound inductor, 220 µH, 110 mA, 5.4 Ohm DCR, unshielded, 1812 SMD.
