Rated at 70 mA continuous current with a maximum DC resistance of 14.5 Ohm, the I²R loss at full load reaches roughly 71 mW — within the thermal budget of the 1812 package in still air. The unshielded construction means the magnetic field radiates; keep sensitive traces or low-impedance loops at least one part width away in layout. ## Self-resonant frequency and Q factor define the usable band With a self-resonant frequency of 2.7 MHz, the inductor behaves inductively from DC up to roughly one decade below that point; above ~2 MHz the impedance becomes capacitive and the part loses its filtering function. A Q factor of 40 at 796 kHz means the inductor stores 40 times more energy than it dissipates per cycle at that frequency — adequate for resonant tank circuits or EMI filters in the 100 kHz to 1 MHz range.","metaTitle":"Murata LQH43NN561K03L Inductor, 560 µH, 70 mA, 1812","metaDescription":"Murata LQH43NN561K03L drum core wirewound inductor, 560 µH ±10%, 70 mA rated current, 14.5 Ohm DCR, 1812 SMD.
