1 µH shielded inductor with AEC-Q200 qualification
The Murata LQH3NPZ1R0MGRL is a drum-core, wirewound inductor in the LQH3 series, shielded and rated for 1 µH ±20% at 1 MHz test frequency. The current rating of 2.08 A and saturation current of 1.7 A mean this part handles the full DC bias without a steep inductance roll-off up to about 1.7 A; beyond that the ferrite core saturates and the inductance drops sharply.
Last-buy lifecycle — what it means for your BOM
Murata has marked the LQH3NPZ1R0MGRL as Last Buy, meaning this exact order code is no longer in continuous production and a final purchase window is open. For a design already qualified on this inductor, the last-buy status means you should secure lifetime buy quantities now.
DC resistance and power loss at 2.08 A
The self-resonant frequency is 100 MHz, which is well above the switching frequency of most automotive buck converters (typically 400 kHz to 2.2 MHz), so the inductor behaves as a pure inductance in that band and the SRF does not limit the design.
