2.2 µH drum core, 0806 footprint
The Murata LQH2MCN2R2M02L is a 2.2 µH unshielded wirewound inductor in the LQH2 series, built on a ferrite drum core and housed in an 0806 (2016 Metric) surface-mount package. Rated for 425 mA continuous current with a maximum DC resistance of 624 mOhm, this part suits low-to-moderate current rails where the DCR-induced conduction loss stays within the thermal budget of the 0806 body. The self-resonant frequency of 70 MHz defines the upper bound of the usable frequency range — above this the inductive impedance rolls off and the component behaves capacitively.
Unshielded construction and board-fit considerations
Unshielded construction means the magnetic field radiates into the surrounding PCB area — adjacent traces carrying sensitive analog signals or high-impedance nodes should maintain a keep-out zone around the inductor footprint to avoid coupling.
