SART Nanjing Sart Tech · Current Sense Resistors / Shunt Resistors · 1206

SMF12M1FR020T from SART Nanjing Sart 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 terminal of the 1206 metal-foil current sensing resistor (R020 = 20 mΩ, ±1%), with a termination length A of 0.50±0.20 mm; the datasheet recommends a separate voltage-sense trace from the land for Kelvin sensing.
2 2 passive Second terminal of the 1206 metal-foil current sensing resistor (R020 = 20 mΩ, ±1%), interchangeable with the first because the part is non-polarized, with a termination length A of 0.50±0.20 mm.
