In a dense mixed-signal layout, the stray field from the drum core can couple into adjacent traces or components — keep a keep-out zone around the part or route sensitive signals on the opposite layer. The self-resonant frequency of 21 MHz means the inductance holds its value up to roughly 7–10 MHz before parasitic capacitance starts to dominate; above that the impedance rolls off. Murata lists the LQH43NN120J03L as Active.","metaTitle":"Murata LQH43NN120J03L Drum Core Inductor, 12 µH, 380 mA","metaDescription":"Murata LQH43NN120J03L drum core wirewound inductor, 12 µH ±5%, 380 mA, 620 mOhm DCR, 1812 SMD, -40°C to 105°C.
