The ±20% tolerance is typical for power inductors where the DC bias curve shifts the inductance anyway — the value at rated current will be lower than the open-circuit figure. Current rating is 720 mA continuous, with a maximum DC resistance of 200 mOhm. At full load the I²R loss is about 104 mW — negligible in most circuits, but if the part sits near a hot regulator the temperature rise adds to the ambient. The self-resonant frequency of 30 MHz means it behaves as an inductor well below that; above it the impedance turns capacitive, so keep the switching noise below 10 MHz for a clean filter. Unshielded construction means the magnetic field radiates — adjacent traces or components on the same layer may pick up noise. For a DC-DC input filter where the inductor is away from sensitive analog lines, the open-core design is fine; for a tight layout with an ADC or RF section nearby, a shielded part from the same LQH43 family would be the safer call. ## 1812 footprint and board integration The surface-mount pads follow the standard 1812 land pattern — no special thermal pad or via array needed. Reflow profile is standard for ferrite-core inductors; the core material is not moisture-sensitive, so no dry-bake step unless the reel has been exposed to high humidity for extended storage. Operating temperature range is -40°C to +85°C, which covers most commercial and industrial environments but not extended automotive under-hood duty. For engine-bay or high-temp applications, a grade with 125°C or 150°C rating would be needed. ## Active lifecycle and sourcing posture The base product number LQH43CN covers the full series, so if a different inductance value or tolerance is needed later, the footprint and package stay the same.","metaTitle":"Murata LQH43CN6R8M03L 6.8 µH Unshielded Inductor, 720 mA","metaDescription":"Murata LQH43CN6R8M03L 6.8 µH ±20% wirewound inductor, 720 mA, 200 mOhm DCR, 1812 SMD.
