Part identity and key parametrics
The LQH31HZR88J03L is a drum-core wirewound inductor from Murata's LQH31 series, housed in a standard 1206 (3216 Metric) surface-mount package. Its 880 nH ±5% inductance is tested at 1 MHz, and the self-resonant frequency reaches 200 MHz — a useful ceiling for RF decoupling or filtering in that band. Rated for 180 mA continuous current with a maximum DC resistance of 1.118 Ohm. The Q factor is 60 at 100 MHz, indicating moderate selectivity in the VHF range.
AEC-Q200 qualified, meaning this inductor passed the automotive-grade stress tests for passive components — thermal shock, humidity bias, vibration, and solder heat resistance. The ferrite core material and unshielded construction mean the magnetic field extends beyond the component body. In a dense layout, keep sensitive traces or other inductors at least one package width away to avoid coupling.
