This qualification means the part is released for use in under-hood and passenger-cabin ECUs without additional PPAP documentation from the inductor supplier. ## 2.2 µH at 610 mA — DC-DC filter fit Rated 2.2 µH ±5% at 1 MHz test frequency, with a 610 mA continuous current rating and 116.4 mOhm max DCR. The 610 mA ceiling sets the load current the inductor can carry before core saturation or thermal runaway — for a buck converter output, this limits the downstream load to roughly 0.5 A at typical switching frequencies, assuming 20-30% ripple current. Self-resonant frequency is 75 MHz — above this point the impedance becomes capacitive, so the inductor is usable for filtering up to the low tens of MHz. The Q factor of 20 at 1 MHz is moderate; adequate for power rail smoothing but not for narrowband resonant tank circuits where a higher Q (50+) would be needed to limit insertion loss. ## Unshielded construction — layout coupling risk The part is unshielded — the ferrite drum core leaves the winding exposed. Magnetic flux radiates from the sides and top of the body. In a dense PCB layout, keep a clearance of at least one part width (3.2 mm) from sensitive analog traces, high-impedance nodes, or adjacent inductors to avoid crosstalk. Operating temperature range is -40°C to 125°C, covering automotive Grade 1 ambient. The ferrite core material maintains inductance stability across this band; the DCR will increase with temperature per the copper winding's positive temperature coefficient, roughly 0.4%/°C.","metaTitle":"Murata LQH32NH2R2J23L Inductor, 2.2 µH, 610 mA, AEC-Q200","metaDescription":"Murata LQH32NH2R2J23L drum core wirewound inductor, 2.2 µH, 610 mA, 116.4 mOhm DCR, AEC-Q200 qualified.
