4.7 µH at 580 mA — DC-bias tradeoff for power rails
The LQH2MPN4R7MGRL is a Murata LQH2-series shielded wirewound inductor offering 4.7 µH inductance with a ±20% tolerance. Rated current is 580 mA, with a saturation current of 870 mA — the DC-bias headroom means the inductance holds within tolerance up to the saturation limit, important for power rail filtering where the load current varies.
DCR and self-resonant frequency
Self-resonant frequency is 40 MHz, setting the upper bound for effective filtering before the component transitions to capacitive behavior.
Shielded ferrite construction for EMI-sensitive layouts
The shielded ferrite core construction reduces magnetic flux leakage, making this inductor suitable for dense PCB layouts where crosstalk to adjacent traces or components must be minimized.
