The Murata LQH32NH271J23L is a drum-core, wirewound inductor from the LQH32 series, rated at 270 µH with ±5% tolerance and a current rating of 55 mA. With a self-resonant frequency of 5 MHz, the inductor maintains its inductive behavior up to that point; beyond 5 MHz the parasitic capacitance dominates and the impedance rolls off — a detail that matters when filtering switching noise from a 2.2 MHz DC-DC converter.
The part is AEC-Q200 qualified for automotive applications. RoHS and REACH compliance documentation is available from Murata upon request.
