With a maximum DC resistance of 392.4 mOhm, the I²R loss at 780 mA is about 240 mW — this self-heating raises the internal temperature above the 85°C ambient ceiling, so a derating check against the actual load current is needed for high-density boards. ## Shielding and frequency response The shielded ferrite core contains the magnetic field lines, reducing radiated EMI that would otherwise couple into adjacent signal traces or the ground plane — important when the inductor sits near a sensitive ADC or RF section on the same PCB. The self-resonant frequency of 15 MHz sets the upper bound for the inductor's impedance peak; above this frequency the component behaves capacitively, so it should not be used as a filter element in switching converters switching above a few megahertz.","metaTitle":"Murata LQH43PH220M26L 22 µH Shielded Power Inductor, 780 mA","metaDescription":"Murata LQH43PH220M26L drum core wirewound inductor, 22 µH, 780 mA, shielded, AEC-Q200.
