Rated for 60 mA with a maximum DC resistance of 22.1 Ohm, this unshielded inductor suits low-current filtering and decoupling applications where board space is tight. The self-resonant frequency of 5 MHz defines the upper frequency limit for effective inductive behaviour — above this point parasitic capacitance dominates and the component behaves capacitively. ## Parametric fit and temperature envelope The 22.1 Ohm DCR at 60 mA produces a self-heating I²R loss of roughly 80 mW — negligible in most circuits, but the temperature rise should be checked against the 85°C ceiling in high-density layouts. Inductance is tested at 1 MHz, confirming the component's performance in the low-MHz switching range common to DC-DC converters and EMI filters.","metaTitle":"Murata LQH32CN391K23L Drum Core Inductor, 390 µH, 60 mA","metaDescription":"Murata LQH32CN391K23L wirewound drum core inductor, 390 µH ±10%, 60 mA rated current, 22.1 Ohm DCR, 1210 package.
