The 110 mA current rating is the DC bias current at which the inductance drops by the specified amount — push past that and you lose inductance fast. The 2.6 Ohm max DCR means at full rated current the copper loss is about 31 mW, which is manageable in a 1206 body but adds up if you have several on a rail. With a self-resonant frequency of 25 MHz, this part is useful for filtering and DC-DC output chokes up to roughly 5-10 MHz before the parasitic capacitance starts to dominate. The ferrite core and ±5% tolerance make it a decent choice for tuned circuits or timing applications where inductance stability matters. ## Last Buy — what it means for procurement This part is in Last Buy status per Murata's lifecycle designation. That means the manufacturer has stopped taking new orders for ongoing production, and only remaining inventory or last-time-buy allocations are available through distribution. If you have an active BOM line using this inductor, now is the time to secure your lifetime buy quantities or qualify a replacement. No official successor is listed for the LQH31MN6R8J03L. For a new design, look at current-production 1206 wirewound inductors from the same series or a cross from a competitor — just watch the DCR and self-resonant frequency. ## Board-fit and handling in a 1206 footprint The unshielded construction means you want to keep sensitive traces or other magnetics at least a couple of millimeters away to avoid coupling. No polarity to worry about, which is one less thing to get wrong on a rework. The tape-and-reel packaging (Cut Tape also available) means it feeds into standard pick-and-place without special handling.","metaTitle":"Murata LQH31MN6R8J03L 6.8 µH Inductor, 110 mA, 1206","metaDescription":"Murata LQH31MN6R8J03L drum core wirewound inductor, 6.8 µH ±5%, 110 mA, 2.6 Ohm DCR, 1206 package.
