Unshielded construction means the magnetic field extends beyond the core — keep sensitive traces or other magnetics at least one body width away to avoid coupling. ## Self-resonant frequency and test conditions Self-resonant frequency is 100 MHz, well above the 1 MHz test frequency used for the inductance measurement — the part behaves as a pure inductor up to roughly 10 MHz, after which parasitic capacitance starts to dominate. Q factor is 20 at 1 MHz, typical for a ferrite-core wirewound at this inductance value — adequate for filtering in DC-DC converter output stages where Q matters less than DCR. Cut Tape suits prototype or low-volume builds.","metaTitle":"Murata LQH32MN1R0M23L Inductor, 1 µH, 445 mA, 1210","metaDescription":"Murata LQH32MN1R0M23L drum core wirewound inductor, 1 µH ±20%, 445 mA, 500 mOhm DCR, 1210 package.
