880 nH, 180 mA — what the ratings tell you
The LQH31HNR88K03L: Rated 880 nH ±10% at a test frequency of 1 MHz, with a maximum DC resistance of 860 mOhm and a continuous current rating of 180 mA. The DCR sets the self-heating floor: at full rated current, the I²R loss is about 28 mW, which is manageable in the 1206 footprint but limits the part to low-power filtering and decoupling roles. The self-resonant frequency is 200 MHz, and the Q factor is 60 at 100 MHz — these figures tell you the inductor behaves as an inductor up to roughly 200 MHz, above which parasitic capacitance dominates. For RF bias-T or impedance-matching networks in the VHF band, the Q of 60 at 100 MHz is a reasonable figure for a ferrite-core wirewound in this package.
Construction and board fit
Drum core wirewound construction on a ferrite core, unshielded — the magnetic field radiates from the open core, so adjacent traces and components need clearance to avoid coupling. Operating temperature range is -40°C to +85°C, which covers industrial and commercial environments but not extended automotive or under-hood applications. The ferrite core material has a Curie temperature well above the 85°C ceiling, so inductance stability across the rated range is typical for this class.
