What AEC-Q200 means for this inductor
Murata LQH43PH1R0N26L is a shielded drum-core wirewound inductor rated for 1 µH at 3.3 A, with a DCR of 31.2 mOhm max. For applications that see sustained 105°C, a higher-temperature-grade variant would be needed.
Shielded construction and board-fit note
The shielded ferrite core reduces radiated EMI — important when the inductor sits near sensitive analog or RF paths on a densely populated PCB. The self-resonant frequency of 100 MHz means the inductance remains stable well into the tens of MHz, covering DC-DC converter switching frequencies up to around 2 MHz with margin. The saturation current (3.4 A) is just above the rated current, so the inductor can handle brief overloads without hard saturation.
