Its 65 mA current rating is the DC current at which the inductance typically drops by 10% — above that the core saturates and the effective inductance falls off. The 10.2 Ohm maximum DCR means the DC voltage drop across the part at full rated current is about 0.66 V, which matters for low-voltage supply rails where the series resistance eats into the headroom. The self-resonant frequency is 6 MHz. Above that the inductor behaves capacitively, so this part is suited for filtering and energy storage in DC-DC converters and signal circuits switching below a few megahertz. The Q factor of 40 at 796 kHz indicates moderate AC losses in that band — adequate for general-purpose filtering but not for high-Q tank circuits. ## Unshielded 1210 footprint — layout and coupling The ferrite core is open, so magnetic flux radiates from the component — adjacent traces and components should be kept at least one package width away to avoid inductive coupling. The nonstandard package code means the pad geometry follows the 1210 footprint per EIA-481, but the winding axis orientation may differ from standard chip inductors; verify the pad layout against the Murata drawing for the LQH32 series.","metaTitle":"Murata LQH32MN181K23L Inductor, 180 µH, 65 mA, 1210","metaDescription":"Murata LQH32MN181K23L drum core wirewound inductor, 180 µH, 65 mA, 10.2 Ohm DCR, unshielded, 1210 package.
