Rated for 45 mA DC current with a maximum DC resistance of 15.6 Ohm — at full rated current the I²R loss is about 31.6 mW, which is within the self-heating budget for this ferrite-core part in still air. The self-resonant frequency of 7 MHz sets the upper bound for inductive behaviour; above this frequency the part becomes capacitive, so it is best suited for filtering and decoupling in circuits operating below a few MHz. Unshielded construction means the magnetic field radiates — adjacent traces carrying sensitive analog signals should be spaced at least one package width away to avoid coupling. The ferrite core material maintains stable inductance across this range, though the DCR will increase with temperature at roughly 0.4%/°C — at 85°C the winding resistance is about 19.5 Ohm, raising the I²R loss to roughly 39 mW at 45 mA.","metaTitle":"Murata LQH31MN101K03L 100 µH Inductor, 45 mA, 1206, Last Buy","metaDescription":"Murata LQH31MN101K03L drum core wirewound inductor, 100 µH ±10%, 45 mA, 15.6 Ohm DCR, 1206 package.
