JER2512F2R001L 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 terminal electrode of the 2512 alloy current-sense resistor (1 mΩ, 2 W per part code; electrode width E 2.20±0.20 mm for the large-electrode type); the element is non-polarized so terminals are interchangeable. |
| 2 | 2 | passive | Other terminal electrode of the 2512 alloy current-sense resistor (1 mΩ, 2 W per part code; electrode width E 2.20±0.20 mm for the large-electrode type); the element is non-polarized so terminals are interchangeable. |
