1.5 µH, 2.45 A — the power rail filter choice
The LQH43CN1R5M33L is a drum-core wirewound inductor from Murata's LQH43 series, rated 1.5 µH at 2.45 A with a maximum DC resistance of 47 mOhm. That DCR at the rated current means the I²R loss stays under 0.3 W — manageable in a 1812 footprint for a buck converter output filter or a point-of-load input choke. The self-resonant frequency of 80 MHz places the usable inductance well above the switching frequency of most DC-DC converters (typically 300 kHz to 2 MHz), so the inductor behaves as a pure inductance in the power loop without capacitive coupling effects.
Ferrite core, unshielded — what it means for layout
The ferrite core material gives stable inductance over temperature and DC bias compared to powdered-iron cores, but the unshielded construction means the flux field extends beyond the part body. Keep sensitive traces or other magnetics at least one part-width away to avoid coupling. For a 1.5 µH output choke in a 1 A buck, the ripple current stays within the DC bias headroom.
