jieerrui · Current Sense Resistors / Shunt Resistors · 1206

RE1206F1R040 from jieerrui, 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 One terminal of the 40 mΩ (R040) 1% alloy current-sense resistor, rated 1 W for the 1206 size, operating from -55°C to +170°C.
2 2 passive Second terminal of the non-polarized 40 mΩ (R040) alloy current-sense resistor, interchangeable with the other terminal, with 1206 solder pad guidance of a=1.8 mm, b=1.7 mm, L=1.6 mm.
