Rated for 40 mA DC with a maximum DC resistance of 37 Ohm, this part suits low-current filtering, bias-T decoupling, and signal-path chokes where the 1.6 MHz self-resonant frequency sets the usable band ceiling. ## Ferrite core and Q factor at 252 kHz The ferrite core material delivers a Q factor of 40 at 252 kHz, indicating moderate AC loss at that frequency — useful for tuned circuits or EMI suppression in the low hundreds of kHz. ## 1812 footprint and reel packaging Supplied on tape and reel (cut tape available), the package supports automated handling for volume production.","metaTitle":"Murata LQH43MN152K03L Inductor, 1.5 mH, 40 mA, 1812","metaDescription":"Murata LQH43MN152K03L drum core wirewound inductor, 1.5 mH, 40 mA, 37 Ohm DCR, 1812 package.
