Rated for 130 mA continuous current with a maximum DC resistance of 3.5 Ohm, this part suits low-current filtering and decoupling roles where the inductance value matters more than the current capacity. ## Self-resonant ceiling at 5.5 MHz The self-resonant frequency of 5.5 MHz sets the upper bound for effective inductive behaviour — above this, parasitic capacitance dominates and the component behaves capacitively. Inductance is tested at 1 MHz, so the part is characterised in the mid-range of its usable band, not at DC or near resonance.","metaTitle":"Murata LQH43CN151K03L Inductor, 150 µH, 130 mA, 1812","metaDescription":"Murata LQH43CN151K03L drum core wirewound inductor, 150 µH, 130 mA, 3.5 Ohm DCR, 1812 package.
