The ferrite core and shielding contain the magnetic flux, reducing radiated EMI in power supply filtering and DC-DC converter output stages. Current handling is specified at 250 mA with a maximum DC resistance of 425 mOhm — the DCR sets the I²R loss and temperature rise in the winding, so a lower DCR is preferred for higher efficiency in battery-powered circuits. The self-resonant frequency is 75 MHz, which means the inductor behaves inductively well below that frequency — it is suitable for switching converters operating in the low-MHz range, such as 2–4 MHz buck regulators. ## AEC-Q200 qualification and temperature grade This inductor is AEC-Q200 qualified — the automotive-grade passive component stress test standard that covers thermal shock, vibration, solder heat resistance, and high-temperature storage. It is not just 'automotive-capable'; it carries the formal qualification an OEM auditor expects for under-hood or cabin electronics. That range suits engine-bay sensors, transmission controllers, and LED headlamp drivers that see sustained ambient heat. ## 1008 footprint and board integration The low profile suits space-constrained layouts on automotive PCBs where component clearance above the board is limited. Surface-mount termination; the tape-and-reel packaging supports automated pick-and-place assembly for volume production. The cut-tape option is available for prototyping or low-volume builds.","metaTitle":"Murata LQH2HNH3R9J03L Inductor, 3.9 µH, Shielded, AEC-Q200","metaDescription":"Murata LQH2HNH3R9J03L drum core wirewound inductor, 3.9 µH ±5%, 250 mA, shielded ferrite core.
