HoLLR2512-3W-80mR-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 resistor terminal (end electrode, C = 0.9±0.2 mm) of the 80 mΩ ±1% element, rated 3 W maximum at up to 70°C, 77.50 A maximum rated current, with the recommended pad A = 4.0±0.1 mm, L = 4.1±0.1 mm, B = 2.1±0.1 mm. |
| 2 | 2 | passive | Second resistor terminal (end electrode) of the 80 mΩ ±1% element, with a Kelvin sensing trace taken from the inner pad edge for resistance measurement, operating from -55 to +170°C. |
