Its 68 µH inductance at 1 MHz test frequency targets DC-DC converter output filtering, power line smoothing, and signal conditioning where moderate current and a compact footprint are required. The unshielded construction means magnetic flux radiates into the surrounding board area; keep sensitive analog traces or ferrite antennas at least one part-width away to avoid coupling. The self-resonant frequency of 8.4 MHz sets the upper bound for effective filtering — above this frequency the inductor behaves capacitively, so it is best suited for switching frequencies below 2-3 MHz where the impedance remains inductive. The Q factor of 35 at 1 MHz indicates moderate efficiency; for higher-Q requirements in tuned circuits, consider a shielded or air-core alternative. ## Active production — sourcing and lifecycle posture The 1812 footprint and ±5% tolerance are consistent across the LQH43 series, so a parametric search on 68 µH / 180 mA / 1812 will surface this exact variant.","metaTitle":"Murata LQH43NN680J03L 68 µH Unshielded Inductor, 180 mA","metaDescription":"Murata LQH43NN680J03L drum core wirewound inductor, 68 µH ±5%, 180 mA, 1.9 Ohm DCR, 1812 SMD.
