Q factor measures 40 at 796 kHz — a moderate figure that reflects the core and winding losses in this unshielded construction, acceptable for general-purpose DC-DC input/output filtering and low-frequency noise suppression.","metaTitle":"Murata LQH43NN271K03L 270 µH Unshielded Inductor, 100 mA","metaDescription":"Murata LQH43NN271K03L wirewound drum core inductor, 270 µH ±10%, 100 mA rated current, 6.8 Ohm DCR, 1812 SMD.
