This combination of inductance and current rating places it in the power-supply filtering and DC-DC converter output roles where the load draws under half an amp and the switching frequency stays below the 33 MHz self-resonant point. The 470 mOhm DCR means the I²R loss at full rated current is about 118 mW — a figure that stays within the 105°C operating ceiling without forced airflow, but one that should be factored into the thermal budget when the inductor sits near other heat sources on a dense board. ## Unshielded construction and board layout This is an unshielded drum core inductor — the magnetic field radiates from the open side of the core. On a mixed-signal board, keep a clearance of at least one part width (4.5 mm) between this inductor and sensitive analog traces or low-noise amplifier inputs to avoid coupling switching ripple into the signal path. The 1812 (4532 Metric) footprint is a standard SMD size that reflows reliably with a typical lead-free profile. The 2.80 mm seated height fits within most low-profile enclosure constraints, but the unshielded top means a metal shield can or enclosure lid close to the component will shift the inductance value — account for proximity effects if the assembly has a cover within 3 mm of the part. ## Active lifecycle — no end-of-line pressure The base product number LQH43NN covers the unshielded variants in the 1812 package; the full suffix (5R6M03L) encodes the 5.6 µH inductance, ±20% tolerance, and packaging code. When ordering, confirm the reel quantity for the Tape & Reel option — the Cut Tape variant is available for prototype quantities.","metaTitle":"Murata LQH43NN5R6M03L 5.6 µH Wirewound Inductor, 500 mA","metaDescription":"Murata LQH43NN5R6M03L drum core wirewound inductor, 5.6 µH ±20%, 500 mA rated current, 470 mOhm DCR, 1812 SMD.
