AEC-Q200 qualification and the Last Buy window
The LQH3NPZR47NGRL carries AEC-Q200 qualification, so it meets the passive-component stress and reliability test suite for automotive electronics — temperature cycling, moisture resistance, mechanical shock, and terminal strength are all documented per the standard. Its operating temperature range is -40°C to 105°C, which covers passenger-compartment and some underhood locations, though a 125°C-rated part would be needed for direct engine-bay mounting. The manufacturer has placed this part on Last Buy status — the order window is closing, and remaining inventory is being drawn down through distribution.
Current ratings and saturation headroom
Rated DC current is 1.52 A, with a saturation current (Isat) of 2.82 A — the inductor can handle nearly double its rated current before the inductance drops by 30%. Maximum DC resistance is 56.4 mOhm, so at the full 1.52 A the I²R loss is about 130 mW — a manageable thermal rise in the 1212 footprint.
Inductance, self-resonance, and shielding
The 470 nH value is tested at 1 MHz, and the self-resonant frequency is 180 MHz — well above the switching frequency of most automotive DC-DC converters (400 kHz to 2.2 MHz), so the inductor behaves as a pure inductive element in that band. The ferrite-core construction is fully shielded, which reduces radiated EMI into adjacent circuitry — a requirement for meeting CISPR 25 conducted and radiated emissions in automotive modules. Tolerance is ±30%, which is typical for power-grade shielded inductors; the saturation and DCR limits are the tighter constraints in a supply rail design, not the absolute inductance value.
