HoLLRX2512-2W-1.5mR-1% from Milliohm, 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 end terminal of the 2512 alloy current-sense resistor (electrode width C 0.9±0.2 mm); the recommended pad is 4.0 mm (A) by 4.1 mm (L) with a separate sensing trace for Kelvin connection. |
| 2 | 2 | passive | Second end terminal of the 2512 alloy current-sense resistor (electrode width C 0.9±0.2 mm); rated 2 W, 0.5~500 mR range, with the same pad geometry and sensing trace for Kelvin connection. |
