Its 160 mA DC current rating is the continuous load limit before self-heating from the 8.04 Ohm max DCR shifts the inductance outside the tolerance band. The saturation current of 230 mA is the hard ceiling where the ferrite core begins to saturate and inductance drops by at least 10% — stay below this for any transient or inrush condition, not just steady-state DC. ## Self-resonant frequency and usable bandwidth With a self-resonant frequency of 7 MHz, this inductor behaves inductively up to roughly 7 MHz; above that the parasitic capacitance between windings dominates and the impedance becomes capacitive. For a buck converter switching at 2 MHz, the 68 µH value is well within the inductive region, but a 10 MHz switching regulator would see the inductor start to look like a capacitor at the fundamental. The ferrite core material sets the frequency-dependent loss profile — at 1 MHz the Q factor is dominated by core loss, not DCR. For filter applications above 1 MHz, verify the impedance roll-off against the circuit's noise bandwidth. ## 0806 footprint and reflow profile The shielded construction contains the magnetic field within the ferrite shield, reducing radiated EMI to adjacent traces and components on a dense PCB. No derating is required below 105°C ambient, but above that the DCR increases with temperature and the saturation current derates per the ferrite's Curie characteristics. ## Active lifecycle and sourcing posture The base product number LQH2MPN covers the full inductance range in this series; the 680 suffix encodes 68 µH.","metaTitle":"Murata LQH2MPN680MGRL 68 µH Shielded Inductor, 160 mA","metaDescription":"Murata LQH2MPN680MGRL 68 µH ±20% shielded wirewound inductor, 160 mA rated, 8.04 Ohm DCR, 0806 package.
