JER1206F1R000 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 resistor terminal of the 1206 alloy current-sense chip (3.20x1.60 mm body, 0.50±0.20 mm electrode width, 1W rated at 70°C ambient, derated linearly to 170°C). |
| 2 | 2 | passive | Other resistor terminal of the 1206 alloy current-sense chip (non-polarized, interchangeable with the other terminal; operating range -55°C to +170°C). |
