15 µH shielded inductor with AEC-Q200 qualification
The Murata LQH3NPZ150MGRL is a 15 µH ±20% drum core wirewound inductor in the LQH3 series, rated for 540 mA continuous current with a saturation current floor of 480 mA. Shielded ferrite core construction contains the magnetic field, reducing radiated EMI into adjacent traces and components — a design consideration for dense automotive or industrial PCBs where crosstalk budgets are tight.
DC resistance maxes at 468 mOhm — at 540 mA the I²R loss is roughly 136 mW, a figure to account for in the local thermal budget, especially in enclosed or high-ambient environments.
Automotive-grade reliability and temperature range
Self-resonant frequency of 15 MHz sets the upper bound for effective filtering — above this frequency the parasitic capacitance across the winding dominates and the inductor behaves capacitively.
Last Buy — sourcing window is closing
Murata has classified the LQH3NPZ150MGRL as Last Buy, meaning the manufacturer has ceased regular production and only remaining factory inventory or surplus-channel stock is available.
