Q factor is 30 at 1 MHz test frequency, typical for a ferrite-core wirewound in this footprint. The Q peak sits well below the SRF, so this part suits narrowband filtering below 10 MHz. 450 mA DC current rating with a maximum DCR of 560 mOhm. ## 1812 SMD — footprint and reflow fit The unshielded drum-core construction means the magnetic field extends beyond the package—adjacent traces and components need clearance to avoid eddy-current losses. The ferrite core is not mechanically pre-stressed by the reel carrier; no special bake-out beyond the standard MSL handling is required. ## Active production — no near-term EOL concern The Murata LQH43MN8R2K03L carries an active product status on the manufacturer's records. No last-time-buy or end-of-life notice has been issued for this LQH43 series variant. For a BOM line already qualified on the 1812 footprint, this part is a stable source.","metaTitle":"Murata LQH43MN8R2K03L 8.2 µH ±10% Inductor, 1812","metaDescription":"Murata LQH43MN8R2K03L drum core wirewound inductor, 8.2 µH ±10%, 450 mA, 560 mOhm DCR, 1812 SMD.
