The saturation point is below the rated current — a 60 mA headroom — so in a buck converter the inductor sees the peak current at the valley of the ripple, not the DC average. If the load transient pushes the peak above 390 mA, the inductance rolls off and the ripple current climbs, which the downstream capacitor must absorb. DC resistance is 636 mOhm max, which at 450 mA produces a 129 mW I²R loss. In a compact 3×3 mm package with a 1 mm seated height, that heat conducts into the PCB copper — the board plane is the heatsink, not the component body. Self-resonant frequency is 10 MHz, tested at 1 MHz. Above 10 MHz the inductor behaves capacitively — the impedance drops and the filtering stops. This part fits switching converters running below 2–3 MHz, where the SRF gives at least a 3× margin. ## Last-buy status and sourcing Murata has marked the LQH3NPZ220MGRL as Last Buy. That means the manufacturer has stopped taking new orders for this order code — the remaining inventory in the distribution channel is the final supply. For a BOM that already qualifies this part, the procurement action is to secure the remaining available units before the channel dries. ## Footprint and board integration Package is 1212 (3030 Metric) — 3.00 mm × 3.00 mm footprint with a 1.00 mm seated height. Surface-mount, shielded construction. The ferrite core and the shield reduce magnetic flux leakage into adjacent traces, which matters when the inductor sits next to a sensitive analog front-end or a feedback resistor divider.","metaTitle":"Murata LQH3NPZ220MGRL 22 µH Shielded Inductor, 450 mA","metaDescription":"Murata LQH3NPZ220MGRL 22 µH shielded wirewound inductor, 450 mA, 636 mOhm DCR, AEC-Q200.
