Its 460 mA continuous current rating and 440 mA saturation current (Isat) define the usable load — the inductor remains within its linear region up to the saturation limit, after which inductance drops sharply and ripple current rises. A 660 mOhm maximum DC resistance sets the I²R conduction loss; at 460 mA the self-heating from DCR alone is roughly 140 mW, which must be factored into the ambient temperature derating for the 105°C maximum operating limit. ## Shielded ferrite core construction for EMI-sensitive circuits The drum-core ferrite construction with magnetic shielding contains the flux field, reducing radiated emissions into adjacent traces and components — important for automotive ECU layouts where switching noise couples into sensor signal chains. The 8 MHz self-resonant frequency (SRF) means this inductor behaves inductively well below 8 MHz; above SRF the impedance becomes capacitive, so it is suited for switching frequencies up to roughly 2-3 MHz where the margin to SRF is adequate. Inductance is tested at 1 MHz, which matches common DC-DC switching frequencies in automotive and industrial power stages. ## Surface-mount footprint and temperature grade Supplied in tape-and-reel packaging (Cut Tape also available), compatible with standard pick-and-place assembly for high-volume production.","metaTitle":"Murata LQH3NPZ330MMEL 33 µH Shielded Inductor, AEC-Q200","metaDescription":"Murata LQH3NPZ330MMEL, 33 µH shielded wirewound inductor, AEC-Q200 qualified, 460 mA, 660 mOhm DCR.

Above this current the ferrite core saturates, inductance drops rapidly, and the ripple current in a DC-DC converter increases — the effective usable current is the lower of the 460 mA rated current and the 440 mA saturation current."},{"question":"What compliance documentation does Murata provide for LQH3NPZ330MMEL?","answer":"As a standard Murata component with AEC-Q200 qualification, RoHS and REACH compliance declarations are available.
