JER2512F3R180 from jieerrui, in a 2512. 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 end electrode of the 2512 (6.40x3.20 mm) alloy current-sense resistor; small electrode width 0.90±0.20 mm, 180 mΩ ±1%, rated up to 3 W (derated above 70 °C), operating range -55 °C to +170 °C. |
| 2 | 2 | passive | Other end electrode of the 2512 alloy current-sense resistor; non-polarized and interchangeable with the opposite electrode, with the resistive element between the two electrodes. |
