What the 110 mA rating means for your filter
The LQH31MN6R8K03L is a 6.8 µH drum-core wirewound inductor in the LQH31 series, rated for 110 mA continuous current with a 2.6 Ohm max DCR. That DCR means at full rated current the inductor drops about 286 mV and dissipates roughly 31 mW as heat — fine for low-power DC-DC or signal filtering, but the voltage drop eats into your rail margin if the load is sensitive. The self-resonant frequency is 25 MHz, so it behaves as an inductor up to about that point; above it the parasitic capacitance takes over. For a buck converter switching at 1-2 MHz, the 25 MHz SRF gives plenty of headroom.
Last-buy lifecycle — what it means for procurement
No official successor is recorded in the lifecycle data. For a BOM line that depends on this exact inductance, current rating, and 1206 footprint, the replacement path may require re-qualifying a similar-value inductor from the same or another series.
Package and rework — 1206 hand-solder friendly
It is a standard two-terminal chip inductor — easy to hand-solder or reflow. No hidden thermal pad, no orientation issues; pin 1 is not a concern on a two-terminal part. Operating temperature range is -40°C to +85°C, which covers most indoor and automotive cabin environments but not under-hood or high-temp industrial zones.
