It is unshielded, so the magnetic field extends beyond the component body — keep a clearance zone around it on the PCB to avoid coupling into adjacent traces or other inductors. The self-resonant frequency is 11 MHz, which means this inductor behaves as an inductor up to roughly that point. Above 11 MHz, parasitic capacitance dominates and the impedance rolls off — use it in DC-DC converter output filters or low-frequency EMI suppression where the switching fundamental stays well below 11 MHz. ## 1210 footprint and surface-mount fit The ferrite core and wirewound construction give it a Q factor of 40 at 1 MHz — decent for a general-purpose power inductor in this footprint. The ±10% tolerance on 39 µH is standard for power-grade inductors; if your design needs tighter inductance tolerance for a tuned filter, this part is not the right pick. ## Active production, available to order No stock-holding claim — we quote to order.","metaTitle":"Murata LQH32MN390K23L 39 µH Unshielded Inductor, 110 mA","metaDescription":"Murata LQH32MN390K23L drum core wirewound inductor, 39 µH ±10%, 110 mA, 3.9 Ohm DCR, 1210 package.
