15 µH, 700 mA — what the ratings mean for your rail
The LQH32PH150MNCL: The 15 µH inductance at 1 MHz test frequency is the value you design the LC filter or output choke around — the 20% tolerance means the actual inductance can drift enough to shift the cutoff frequency of a low-pass filter by about 20%, so budget the corner frequency with margin. 700 mA continuous current rating is the DC bias limit before self-heating raises the temperature above the 85°C ambient ceiling. The saturation current is 800 mA — only 100 mA above the rated current, so a transient that pushes the inductor into saturation will collapse the inductance and spike the ripple current through the downstream capacitor.
AEC-Q200 and the 85°C ceiling
The 570 mOhm max DCR at 700 mA produces an I²R loss of about 0.28 W — that heat must be conducted through the 1210 (3225 Metric) footprint into the PCB copper pour; a narrow trace under the pad will raise the local temperature above the 85°C limit.
