The 80 mA current rating and 11.8 Ohm max DC resistance define the usable load range — above 80 mA the core saturates and inductance collapses, and the DCR sets the I²R heating that drives the temperature rise inside the 1812 package. ## Q factor and self-resonant frequency Q is 40 minimum at 796 kHz, which is a typical test point for medium-value inductors — adequate for filtering and tank circuits in that band. The self-resonant frequency is 3 MHz; above that the inductor behaves capacitively, so this part is not suitable for RF applications above a few MHz.","metaTitle":"Murata LQH43MN471J03L Drum Core Inductor, 470 µH, 80 mA","metaDescription":"Murata LQH43MN471J03L unshielded wirewound inductor, 470 µH ±5%, 80 mA, 11.8 Ohm DCR, 1812 SMD.
