RLS12FTCR020 from TA I Tech, 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 end terminal (copper-plated electrode, C = 0.50±0.30 mm) of the RLS12 1206 metal-foil current sensing resistor; rated 1 W (code C), 5 to 40 mΩ, -55°C to +155°C. |
| 2 | 2 | passive | Second end terminal of the RLS12 1206 current sensing resistor, interchangeable with the first (non-polarized); the resistive element lies between the two terminals, with the sensing trace taken from the pads per the recommended layout on page 4. |
