LRAM12CFTR003 from NCT, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | First electrode of the 3.2 x 1.6 mm 1206 alloy current-sense resistor (LRA12* series, 1 mΩ for R003 suffix variants per the part-number code), with 4-wire measurement taken on the back electrode. |
| 2 | 2 | passive | Second electrode of the 3.2 x 1.6 mm 1206 alloy current-sense resistor, non-polarized and interchangeable with the first electrode. |
