For a buck converter switching at 1–2 MHz, this part offers clean filtering headroom. A Q factor of 35 at 1 MHz indicates moderate energy storage efficiency at that frequency — adequate for general-purpose filtering and decoupling in power supplies and RF bias-T circuits where the operating frequency stays well below self-resonance. ## Unshielded construction and layout considerations This is an unshielded inductor, so its magnetic field radiates into the surrounding PCB area. Keep sensitive analog traces or high-impedance nodes at least two board-layer thicknesses away from the component to avoid coupling.","metaTitle":"Murata LQH43NN150K03L Inductor, 15 µH, 360 mA, 1812","metaDescription":"Murata LQH43NN150K03L drum core wirewound inductor, 15 µH ±10%, 360 mA, 730 mOhm DCR, 1812 SMD.
