The 470 mOhm max DCR means the I²R loss hits 118 mW at full rated current—enough to raise the core temperature above ambient in a compact 1812 package. Unshielded construction with a ferrite core: the stray magnetic field couples into nearby PCB traces, so the layout should keep sensitive analog or high-impedance nodes at least a few millimeters away from the inductor body. ## Industrial temperature grade and package The tape-and-reel packaging (Cut Tape also available) suits pick-and-place assembly for medium-volume production runs. ## Self-resonant frequency and Q factor Self-resonant frequency is 33 MHz; above that the inductor behaves capacitively. The Q factor is 30 at 1 MHz—moderate for a drum-core wirewound, adequate for DC-DC converter output chokes and general filtering where the Q is not the primary selection axis.","metaTitle":"Murata LQH43MN5R6K03L 5.6 µH 500 mA Unshielded Inductor","metaDescription":"Murata LQH43MN5R6K03L drum-core wirewound inductor, 5.6 µH ±10%, 500 mA, 470 mOhm DCR, 1812 SMD.
