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.","metaTitle":"Murata LQH32NZ3R3K23L Inductor, 3.3 µH, 300 mA, AEC-Q200","metaDescription":"Murata LQH32NZ3R3K23L drum core wirewound inductor, 3.3 µH, 300 mA, 1210 SMD, AEC-Q200.
