4.7 µH drum core for power-line filtering
The Murata LQH43CN4R7M03L is a drum-core wirewound inductor in the LQH43 series, rated 4.7 µH ±20% with a 750 mA current rating and 150 mOhm max DCR. The unshielded ferrite core suits DC-DC converter input/output filtering and power-supply decoupling where the inductor sits away from sensitive analog traces.
1812 footprint and board integration
The tape-and-reel delivery (cut tape also available) feeds standard pick-and-place lines; the 1812 footprint is a common size for power inductors, so the pad layout is shared across multiple suppliers.
Self-resonant frequency and test conditions
Self-resonant frequency is 35 MHz, well above the 1 MHz test frequency used for the inductance measurement. The 150 mOhm max DCR at 750 mA means the I²R loss is roughly 84 mW at full rated current — the part stays cool in most power rail applications without forced airflow.
