Its 240 mA continuous current rating and 220 mA saturation current define the usable load range — the inductor stays within its linear region as long as the peak current stays below the saturation floor. The 3.48 Ω maximum DC resistance sets the I²R copper loss budget at full current: at 240 mA the winding dissipates roughly 200 mW. For a 4.5 mm × 3.2 mm shielded ferrite-core part seated at 2.8 mm, that heat is manageable in still air but should be checked against the local board temperature rise in a dense power supply layout. ## AEC-Q200 qualification and the operating envelope Rated AEC-Q200, this inductor meets the automotive-grade stress tests for temperature cycling, mechanical shock, vibration, and solder heat resistance. ## Shielded construction and board-fit note The shielded ferrite core contains the magnetic flux, reducing radiated emissions into nearby traces or sensitive analog circuits. This matters when the inductor sits next to a DC-DC converter switching at 1–2 MHz — the self-resonant frequency of 2 MHz means the inductor is inductive up to roughly 1.5 MHz, after which parasitic capacitance dominates and filtering effectiveness drops. Packaged on tape and reel with cut-tape option, the nonstandard 4.50 mm × 3.20 mm footprint is the same as the industry-common 4.5×3.2 mm shielded inductor land pattern.","metaTitle":"Murata LQH43PH221M26L 220µH Shielded Inductor, AEC-Q200","metaDescription":"Active Murata LQH43PH221M26L drum-core wirewound inductor, 220 µH ±20%, 240 mA, shielded, AEC-Q200 qualified.
