Active production, AEC-Q200 qualified
The LQH32NZ3R3K23L: AEC-Q200 qualification certifies this inductor for automotive-grade stress testing — temperature cycling, humidity bias, and mechanical shock per the passive-component reliability standard.
3.3 µH, 300 mA, 1 Ohm DCR — the power-stage choke profile
3.3 µH inductance at 1 MHz test frequency with a 300 mA continuous current rating and 1 Ohm max DCR places this squarely as a DC-DC converter output inductor or input-line filter choke for low-power rails. The 300 mA ceiling is the saturation-limited current; the DCR contributes a 90 mW I²R loss at full load — negligible in most designs but worth budgeting in a thermally constrained 1210 footprint. Self-resonant frequency of 38 MHz means the inductive impedance dominates well above the 1-2 MHz switching frequencies common in automotive-grade converters. The Q factor of 20 at 1 MHz indicates moderate AC losses — acceptable for power filtering, not a tuned tank circuit.
Unshielded drum core — placement matters
Drum core, wirewound construction with a ferrite core and no magnetic shield means the inductor radiates a fringe field. In a dense 1210 layout, keep sensitive analog traces or low-level sensor inputs at least two part-widths away — the unshielded field couples into adjacent loops. The 3.20mm x 2.50mm footprint with 2.20mm seated height fits standard 1210 pads; no special land pattern required.
