1 µH, 500 mA drum core for power filtering
The Murata LQH43NN1R0M03L is a wirewound drum core inductor in the LQH43 series, offering 1 µH inductance with ±20% tolerance and a current rating of 500 mA. Its 200 mOhm maximum DC resistance keeps conduction losses manageable at rated current, while the unshielded construction means the magnetic field extends beyond the part — board layout should keep sensitive traces and other inductors clear of the flux path.
1812 footprint and self-resonant frequency
The self-resonant frequency of 120 MHz defines the upper usable band — above that point the component behaves capacitively, so for filtering or DC-DC converter applications keep the switching frequency well below 120 MHz to stay in the inductive region.
