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. |
