Its self-resonant frequency of 40 MHz means it stays inductive well into the switching range of most buck converters operating at 1–2 MHz, where the SRF is typically 10–20× the switching frequency. The saturation current is specified at 1.3 A, 30% above the rated current — a healthy margin that keeps the inductance roll-off gradual under transient load steps. This is typical for a power-grade ferrite-core inductor designed for continuous conduction mode in a regulator output filter. ## Automotive qualification and operating envelope AEC-Q200 qualification means this inductor has passed the full suite of stress tests required for automotive-grade passive components: thermal shock, moisture resistance, mechanical shock, vibration, and solder heat resistance. ## Board-fit and footprint The shielded ferrite core construction contains the magnetic flux, reducing radiated EMI into adjacent traces or sensitive analog circuits on the same board layer. Surface-mount termination with a ±20% inductance tolerance is standard for power inductors used in output filter applications, where the closed-loop regulator compensates for the inductance spread. The 1 MHz test frequency is the industry-standard condition for measuring inductance in the 1–10 µH range.","metaTitle":"Murata LQH3NPZ4R7MMEL 4.7 µH Shielded Inductor, 1 A","metaDescription":"Murata LQH3NPZ4R7MMEL, 4.7 µH shielded wirewound inductor, 1 A rated, 120 mOhm DCR, AEC-Q200.
