HoYLR2512-2W-25mR-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 25 mΩ ±1% 2 W alloy current-sense resistor (terminal width C 0.9±0.2 mm, recommended pad 4.0±0.1 × 2.1±0.1 mm). |
| 2 | 2 | passive | Second end terminal of the 25 mΩ ±1% 2 W alloy current-sense resistor, interchangeable with the first (max rated current 8.94 A, operating -55 to +170 °C). |
