3.3 µH shielded wirewound for automotive power rails
The Murata LQH3NPZ3R3MGRL is a drum-core, wirewound shielded inductor in the LQH3 series, rated 3.3 µH ±20% at 1 MHz test frequency. Its 940 mA continuous current rating and 1.05 A saturation current (Isat) suit it for DC-DC converter input/output filtering in automotive body electronics, infotainment, and ADAS sensor modules where the inductor must hold inductance under peak load transients.
AEC-Q200 qualification and shielded construction
The ferrite core and full magnetic shield contain the flux field, reducing radiated EMI into nearby sensitive circuits — a requirement when the inductor sits adjacent to RF transceivers or high-speed data lines on the same PCB. Self-resonant frequency is 30 MHz, well above the 1–4 MHz switching frequencies typical of automotive buck converters, so the inductor behaves as a pure inductance in the passband.
Last-buy status — plan the BOM now
Murata has placed the LQH3NPZ3R3MGRL in Last Buy status — the manufacturer will accept final orders only during a defined window, after which the part is discontinued. For existing designs that require this exact inductance, current rating, and footprint, the last-time-buy is the only path to secure production inventory. Store the reels dry (MSL not stated, but standard moisture-barrier bagging is assumed for tape-and-reel product).
