JER2512F3R000 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 | First terminal electrode of the 2512 alloy current-sense resistor (JER2512F3R000, 3W, 1%, 3mΩ); 2512 electrode width is 2.20±0.20 mm (large electrode) or 0.90±0.20 mm (small electrode), and the resistor is non-polarized. |
| 2 | 2 | passive | Second terminal electrode of the 2512 alloy current-sense resistor (JER2512F3R000, 3W, 1%, 3mΩ); rated up to 3W with derating above 70°C and an operating range of -55°C to +170°C, and the resistor is non-polarized. |
