470 µH wirewound in the 1812 footprint
The Murata LQH43NN471K03L is a drum-core wirewound inductor in the LQH43 series, delivering 470 µH ±10% in an unshielded 1812 (4532 Metric) SMD package. 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
