150 µH wirewound in a 1812 body with AEC-Q200
The Murata LQH43NH151J03L is a drum-core wirewound inductor from the LQH43 series, offering 150 µH inductance with ±5% tolerance in a standard 1812 (4532 Metric) surface-mount package. Rated for 120 mA DC with a maximum DC resistance of 3.6 Ω, this part is sized for power-supply filtering, DC-DC converter output chokes, and noise suppression in automotive or industrial circuits where the AEC-Q200 qualification certifies reliability under thermal and mechanical stress per the automotive-grade IC qualification standard.
Frequency response and self-resonance limits
With a self-resonant frequency of 5.5 MHz and a Q factor of 40 at 796 kHz, the LQH43NH151J03L maintains inductive impedance up to several megahertz — above SRF the component becomes capacitive, so the usable filter band stops well before 5.5 MHz.
