Its 165 mA current rating and 370 mOhm DCR define the DC loss and load ceiling for filtering and DC-DC output stages. ## Frequency response and Q factor The self-resonant frequency of 90 MHz sets the upper bound for inductive behaviour; above this frequency the component acts capacitively. A Q of 35 at 10 MHz is typical for a ferrite-core wirewound in this inductance range, adequate for general-purpose filtering but not for narrowband resonant circuits that require a higher Q. The unshielded construction means magnetic flux couples into nearby traces and components — layout should keep sensitive signal paths at least a component width away.","metaTitle":"Murata LQH31MN1R2J03L Inductor, 1.2 µH, 165 mA, 1206","metaDescription":"Murata LQH31MN1R2J03L drum-core wirewound inductor, 1.2 µH ±5%, 165 mA, 370 mOhm DCR, 1206 SMT.
