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.","metaTitle":"Murata LQH43CN4R7M03L Drum Core Inductor, 4.7 µH, 750 mA","metaDescription":"Murata LQH43CN4R7M03L drum core wirewound inductor, 4.7 µH ±20%, 750 mA, 150 mOhm DCR, 1812 SMD.
