The shield contains the flux field so the inductor can sit next to sensitive analog or RF circuitry without coupling noise into adjacent traces — a common headache in dense mixed-signal boards. Rated at 47 µH ±20% with a continuous DC current of 520 mA, it handles moderate power-supply filtering and DC-DC converter output ripple roles. The saturation current is 470 mA, meaning the inductance starts to roll off above that point — keep the peak inductor current below that figure to stay in the linear region. The self-resonant frequency is 8 MHz, which sets the upper bound for useful filtering — above that frequency the inductor behaves capacitively, so it is best suited for switching regulators switching in the hundreds-of-kHz range. ## AEC-Q200 qualification and automotive-grade reliability This inductor carries AEC-Q200 qualification, the passive-component stress-test standard for automotive electronics. For engine-bay or high-ambient applications above 85°C, you would need a wider-temperature-grade part. ## Package and board-fit details The footprint is not a standard 1812 or 1212 — verify the land pattern against the manufacturer's recommended pad layout before committing the PCB. Available in Tape & Reel (TR) or Cut Tape (CT) packaging. The TR option is the production-friendly reel for pick-and-place; CT is for prototyping or small-batch builds. The base product number is LQH43PH, so the full 14-character code LQH43PH470M26L encodes the inductance, tolerance, and packaging variant.","metaTitle":"Murata LQH43PH470M26L Shielded Power Inductor, 47 µH, 520 mA","metaDescription":"Murata LQH43PH470M26L drum core wirewound inductor, 47 µH ±20%, 520 mA, shielded, AEC-Q200, -40 to +85°C.

Above this current the ferrite core begins to saturate, causing the inductance to drop sharply. For a 520 mA rated current part, the saturation margin is tight — the peak inductor current in the circuit must stay below 470 mA to maintain the full 47 µH value."},{"question":"What compliance documentation is available for this inductor?","answer":"Murata provides RoHS and REACH compliance declarations for the LQH43PH series.
