150 µH at 80 mA — the load-current ceiling
The LQH32NH151J23L is a drum core wirewound inductor from Murata's LQH32 series, rated 150 µH ±5% at 1 MHz with a maximum DC resistance of 5.82 Ohm. The 80 mA current rating sets the continuous load limit — exceeding it drives the core into saturation and pushes the DCR loss above the self-heating budget. Unshielded construction means the magnetic field radiates beyond the component body — keep sensitive traces or other magnetics at least one body width away to avoid coupling.
AEC-Q200 and the automotive bill-of-material
AEC-Q200 qualification means this inductor passed the stress tests for automotive-grade passive components — thermal shock, vibration, solder heat, and biased humidity. It suits under-hood or cabin electronics where the part must survive the engine-bay thermal profile and the supply chain demands PPAP-ready documentation. Production status is active per Murata's current lifecycle designation.
Self-resonant frequency and filter placement
The self-resonant frequency is 8 MHz — above this the inductor behaves capacitively. For a DC-DC filter or EMI suppression stage, the switching noise must fall below 8 MHz to stay in the inductive region. The Q factor of 40 at 1 MHz gives a reasonable selectivity for bandpass or resonant tank circuits in that band. Tape-and-reel and cut-tape options are available for prototyping or volume pick-and-place. The nonstandard case footprint matches the LQH32 series land pattern — confirm the pad geometry against your PCB layout before committing.
