The 200 mA current rating is the continuous DC bias limit at 25°C ambient — exceeding this saturates the ferrite core and collapses the inductance. The 1.7 Ohm DCR produces a 68 mV voltage drop at full rated current, which factors into the downstream rail budget. ## Unshielded ferrite core — layout matters This is an unshielded inductor on a ferrite core. Magnetic flux radiates from the component body, so keep it 2–3 mm away from sensitive analog traces, shielded inductors, or low-level signal paths on the same layer. The self-resonant frequency of 9.3 MHz sets the upper useful band — above that the inductor behaves capacitively. Q factor is 35 at 1 MHz, adequate for tank circuits and resonant converters in that range.","metaTitle":"Murata LQH43NN560J03L 56µH Inductor, 200mA, 1812","metaDescription":"Murata LQH43NN560J03L drum-core wirewound inductor, 56 µH ±5%, 200 mA rated current, 1.7 Ohm DCR max, 1812 SMD package.
