These three numbers — inductance, current, and DCR — define its role in a buck converter's output filter or a point-of-load input stage: the inductance sets the ripple current, the current rating must exceed the peak inductor current with margin, and the DCR contributes to the I²R conduction loss that drives the temperature rise. The saturation current is 1.52 A, providing about 32 % headroom above the rated current before the inductance begins to roll off. This margin is typical for a power inductor designed to handle transient load steps without saturating the ferrite core. ## 1212 (3030 Metric) footprint The shielded construction contains the magnetic flux within the core, reducing radiated EMI into adjacent traces or components — relevant when the inductor sits near a sensitive analog or RF section on the same board. The self-resonant frequency is 55 MHz, well above the typical 1–4 MHz switching frequency of a DC-DC converter using a 3.3 µH inductor, so the inductor behaves as a pure inductive element in the switching band.","metaTitle":"Murata LQH3NPZ3R3MMEL 3.3 µH Shielded Inductor, 1.15 A","metaDescription":"Murata LQH3NPZ3R3MMEL drum core wirewound inductor, 3.3 µH ±20%, 1.15 A, 100.8 mOhm DCR, AEC-Q200, shielded, 1212 package.
