Rated for 270 mA continuous current with a saturation floor of 260 mA, the part suits low-to-moderate current DC-DC converter output stages or input pi-filters where the peak inductor current stays below the saturation knee. The 1.68 Ω maximum DCR sets the I²R conduction loss — at 270 mA the copper loss is roughly 122 mW, which the 105 °C temperature ceiling can dissipate without derating in still air. ## Shielded construction and self-resonant frequency The ferrite core and shielded winding contain the magnetic flux, reducing radiated EMI that would otherwise couple into adjacent signal traces or the ground plane — a practical advantage when the inductor sits near a sensitive ADC or RF front-end. Self-resonant frequency is 5 MHz, meaning the inductor behaves inductively up to roughly that point; above 5 MHz the parasitic capacitance dominates and the impedance rolls off, so this part is best suited for switching frequencies well below 5 MHz. Inductance is tested at 1 MHz, which is within the inductive region and gives a reliable nominal value for the design calculation.","metaTitle":"Murata LQH3NPN470MGRL Shielded Power Inductor, 47 µH","metaDescription":"Murata LQH3NPN470MGRL drum core wirewound inductor, 47 µH ±20%, 270 mA, shielded, 1212 package.
