Its 25 mA current rating and 53 Ohm maximum DC resistance suit low-current filtering and decoupling roles where board space is tight. The ferrite core and wirewound construction deliver a self-resonant frequency of 1.2 MHz and a Q factor of 40 at 252 kHz, making it a reasonable fit for LC tank circuits or noise suppression below 1 MHz. The 1812 footprint and standard tape-and-reel packaging mean it integrates into existing pick-and-place setups without a process change. ## What the ratings mean for the BOM The 25 mA current rating is the DC bias current at which the inductance typically drops by 10% — stay below this to avoid saturation in a choke or filter. The 53 Ohm DCR means the DC voltage drop at full rated current is about 1.3 V, so this part is best suited to signal-path or low-power bias lines rather than power rails. The ±5% tolerance holds the inductance value across the range, important for tuned circuits where frequency stability matters.","metaTitle":"Murata LQH43NN242J03L Inductor, 2.4 mH, 25 mA, 1812","metaDescription":"Murata LQH43NN242J03L drum core wirewound inductor, 2.4 mH ±5%, 25 mA rated current, 53 Ohm DCR, 1812 SMD.
