Unshielded construction means the magnetic field extends beyond the component body; keep a clearance zone around the part in layout to avoid coupling into adjacent traces or sensitive analog loops.","metaTitle":"Murata LQH31MN2R7K03L Inductor, 2.7 µH, 135 mA, 1206","metaDescription":"Murata LQH31MN2R7K03L drum core wirewound inductor, 2.7 µH, 135 mA, 715 mOhm DCR, 1206 package.
