With a self-resonant frequency of 2.5 MHz, this inductor is effective below that point; above it the component behaves capacitively. Q factor of 40 at 796 kHz indicates moderate AC losses at that test frequency — useful for tuned circuits or filter stages where the Q is a design input, not just a datasheet number. The 15.48 Ohm DCR produces roughly 46 mW of I²R loss at rated current — negligible in most circuits but a factor in ultra-low-power rails where every milliwatt is budgeted. ## AEC-Q200 and the 1812 footprint Active status means the manufacturer continues to produce and support this order code — no last-time-buy clock is running, and the part remains eligible for new designs that require a qualified inductor at this inductance and current.","metaTitle":"Murata LQH43NH681J03L 680µH Inductor, 55mA, AEC-Q200","metaDescription":"Murata LQH43NH681J03L wirewound drum core inductor, 680 µH ±5%, 55 mA, 15.48 Ohm DCR, AEC-Q200, 1812 package.
