JER1206F1R004 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 | First terminal electrode of the 4 mΩ (R004) 1% current-sense resistor, electrode width 0.50±0.20 mm, rated 1 W at up to 70 °C ambient and derated linearly above that to +170 °C. |
| 2 | 2 | passive | Second terminal electrode of the 4 mΩ (R004) 1% current-sense resistor, electrode width 0.50±0.20 mm, interchangeable with the first terminal, with TCR ±50 ppm/°C for 2 mΩ to 100 mΩ. |
