Shielded 15 µH power inductor with AEC-Q200 qualification
The Murata LQH3NPH150MMEL is a shielded drum-core wirewound inductor in the LQH3 series, rated 15 µH ±20% with a continuous current rating of 1.02 A and a saturation current of 660 mA. The shielded ferrite core construction contains the magnetic flux, reducing radiated EMI to adjacent traces and components — a design consideration for dense PCB layouts in engine control units or sensor modules.
Parametric fit for the BOM line
The 15 µH nominal inductance is tested at 1 MHz; the self-resonant frequency is 15 MHz, well above the switching frequencies of typical DC-DC converters in automotive power stages. Maximum DC resistance is 348 mOhm — at 1.02 A the I²R loss is about 0.36 W, which the 1212 (3030 Metric) package dissipates without exceeding the 125°C upper operating limit. The saturation current of 660 mA is the point where inductance drops by 30%; the continuous current rating of 1.02 A is thermally limited, so the application must stay below the lower of the two limits depending on whether the load is steady-state or transient.
Surface-mount package 1212 (3030 Metric), 3.00 mm x 3.00 mm footprint, seated height 1.50 mm — the low profile suits space-constrained automotive modules such as ADAS camera boards or keyless-entry receivers. Supplied in Tape & Reel (TR) or Cut Tape (CT) — the reel quantity is set by the manufacturer's standard packaging; confirm the reel count at RFQ for production volume.
AEC-Q200 qualification is the primary compliance marker; the part is designed for automotive PPAP-level documentation. RoHS and REACH compliance are standard for the LQH3 series but are not explicitly listed in the spec record — confirm at RFQ if a full compliance declaration is required.
