Rated for 390 mA continuous current with a maximum DC resistance of 360 mOhm, this part suits power-supply filtering and DC-DC converter output stages where the current draw stays under the rating. ## Frequency response and AC losses The self-resonant frequency of 19 MHz sets the upper bound for inductive behaviour — above this frequency the part looks capacitive, so keep the switching or ripple frequency below 19 MHz to maintain the intended filtering action. A quality factor (Q) of 35 at 1 MHz indicates moderate AC loss at that frequency; for resonant tank circuits or RF bias feeds, the Q figure helps estimate the insertion loss and bandwidth. The ferrite core material and unshielded construction mean the inductor radiates a small magnetic field — keep sensitive traces or other magnetics at least a few millimetres away on the PCB to avoid coupling.","metaTitle":"Murata LQH43NH150J03L 15 µH Wirewound Inductor, AEC-Q200","metaDescription":"Murata LQH43NH150J03L drum core wirewound inductor, 15 µH ±5%, 390 mA, 360 mOhm DCR, AEC-Q200 qualified, 1812 SMD.
