56 µH in an 0806 — what the ratings mean for the board
The Murata LQH2MCN560K02L is a 56 µH drum core wirewound inductor in the LQH2 series, housed in an 0806 (2015 Metric) surface-mount package. The ferrite core and wirewound construction give it a self-resonant frequency of 17 MHz, meaning it behaves as an inductor up to roughly that frequency — above 17 MHz the parasitic capacitance dominates and the impedance rolls off. The 110 mA current rating is the DC current at which the inductance typically drops by 10 % due to core saturation. With a maximum DC resistance of 7.41 Ohm, the I²R loss at full rated current is about 90 mW — modest for an 0806 body, but worth checking against the board's local heating budget if the inductor sits near a temperature-sensitive component.
Unshielded — plan the layout accordingly
This part is unshielded, so the magnetic field from the drum core radiates into the nearby PCB area. Keep sensitive analog traces, low-level signal lines, and other magnetics at least a few millimeters away, or place a ground plane beneath the inductor to contain the field.
