Its 230 mA current rating and 450 mOhm DCR set the DC bias limit and conduction loss for the trace or supply rail it feeds. ## Self-resonant frequency and Q — where this inductor stops being an inductor With a self-resonant frequency of 250 MHz and a Q of 30 at 25 MHz, this part behaves as a pure inductance up to roughly 200 MHz. Above SRF the impedance turns capacitive, so it suits low-pass filter stages and DC-DC converter snubbers operating in the VHF band, not UHF. ## Unshielded construction — placement matters on a mixed-signal board The unshielded ferrite core means magnetic flux couples into nearby traces and components. On a board with sensitive analog or RF front-ends, keep a keep-out zone of at least 2–3 mm around the part, or switch to a shielded variant in the same LQH31 family if cross-talk becomes an issue. ## Temperature range and board-fit reality The 1206 footprint reflows on standard FR-4 with no special paste or profile adjustments.","metaTitle":"Murata LQH31MNR33K03L 330 nH Inductor, 230 mA, 1206","metaDescription":"Murata LQH31MNR33K03L drum core wirewound inductor, 330 nH ±10%, 230 mA, 450 mOhm DCR, 250 MHz SRF, 1206 package.
