Q factor is 35 at 1 MHz, measured at the test frequency — this is a moderate Q for a ferrite-core wirewound in this inductance range, adequate for general-purpose filtering and bias-tee circuits where low loss is not the primary constraint.","metaTitle":"Murata LQH43MN100J03L Inductor, 10 µH, 400 mA, 1812","metaDescription":"Murata LQH43MN100J03L drum core wirewound inductor, 10 µH ±5%, 400 mA, 560 mOhm DCR, 1812 SMD.
