Rated for 80 mA continuous current, with a maximum DC resistance of 11.8 Ohm — the DCR at this inductance value is the limiting factor for I²R heating in the winding, so the 80 mA rating already accounts for the temperature rise at full load. The ferrite core and wirewound construction give a Q factor of 40 at 796 kHz, and the self-resonant frequency sits at 3 MHz — above that frequency the component behaves capacitively, so the inductor is best used in filtering or DC-bias circuits below the SRF. ## Sourcing and compliance Supplied in Tape & Reel (TR) or Cut Tape (CT) packaging, compatible with standard pick-and-place assembly for the 1812 footprint.","metaTitle":"Murata LQH43NN471K03L 470µH Unshielded Inductor, 80mA","metaDescription":"Murata LQH43NN471K03L wirewound ferrite-core inductor, 470 µH ±10%, 80 mA, 11.8 Ohm DCR, 1812 SMD.
