The 2.5 Ohm max DCR sets the copper loss at full load — at 160 mA the I²R loss is 64 mW, which drives the temperature rise above ambient. For a filter or DC-DC output stage, the self-resonant frequency of 6.8 MHz defines the upper bound of usable frequency; above that the impedance turns capacitive and the inductor no longer performs as intended. ## 1812 footprint and reflow assembly The unshielded construction means the magnetic field extends beyond the package — keep a clearance of at least one part width to adjacent traces or components to avoid coupling noise into the signal path.","metaTitle":"Murata LQH43NN101J03L 100 µH Unshielded Inductor, 160 mA","metaDescription":"Murata LQH43NN101J03L drum core wirewound inductor, 100 µH ±5%, 160 mA, 2.5 Ohm DCR, 1812 package.
