It is rated for 130 mA continuous current with a maximum DC resistance of 2.86 Ohm — the DCR figure sets the I²R heating floor for the winding, so the 130 mA rating already accounts for self-heating at the top of the -40 to +105 °C operating range. The self-resonant frequency is 12 MHz, measured at 1 MHz test frequency. Above 12 MHz the inductor behaves capacitively, so this part suits switching regulators and filter stages where the fundamental ripple or signal frequency stays well below that threshold — typical for buck converter output chokes or EMI line filters in the 100 kHz to few MHz band. ## 1210 footprint and board-fit constraints The unshielded construction means the magnetic field extends beyond the package — adjacent traces carrying sensitive analog signals or high-speed edges should be kept at least one body width away to avoid coupling. The ±10 % tolerance on 68 µH is standard for power-stage inductors where the closed-loop control compensates for the inductance spread. If the design requires tighter tolerance for a resonant tank or tuned filter, a ±5 % or ±2 % part from the same LQH32 family would be the next step up.","metaTitle":"Murata LQH32DN680K23L 68 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH32DN680K23L drum core wirewound inductor, 68 µH ±10%, 130 mA, 2.86 Ohm DCR, 12 MHz SRF, -40 to +105 °C.
