Q factor of 35 at 1 MHz indicates moderate losses at the test frequency — adequate for general-purpose filtering but not the lowest-loss choice for high-Q resonant circuits like tank filters.","metaTitle":"Murata LQH43MN150K03L Inductor, 15 µH, 360 mA, 1812","metaDescription":"Murata LQH43MN150K03L drum core wirewound inductor, 15 µH ±10%, 360 mA, 730 mOhm DCR, 1812 SMD.
