Its unshielded ferrite-core construction and 23 MHz self-resonant frequency suit it for low-current filtering, decoupling, or resonant tank circuits on a 1206 footprint. ## Last Buy — what it means for your BOM Murata has marked this part Last Buy — the manufacturer's last production run is in progress or has closed, and remaining inventory is finite. For a repair bench or a production line that still needs this exact inductance value in a 1206 package, the window to secure stock is now. ## Parametric fit — what the ratings mean The Q factor of 35 at 8 MHz and self-resonant frequency of 23 MHz tell you the inductor behaves as an inductor up to roughly 23 MHz; above that, parasitic capacitance dominates. For a tuned circuit at 10 MHz, the Q is adequate; for a 50 MHz filter, the part is outside its useful band.","metaTitle":"Murata LQH31MN8R2J03L 8.2 µH Inductor, 105 mA, Last Buy","metaDescription":"Murata LQH31MN8R2J03L drum core wirewound inductor, 8.2 µH, 105 mA, 1206 package.
