HoYLR2512-3W-60mR-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 (2512 two-terminal alloy current-sense resistor, 60 mΩ ±1%, 3 W rated power at 70°C ambient, max rated current 7.07A); the datasheet prints no pin numbers, terminals are interchangeable. |
| 2 | 2 | passive | Second resistor terminal (60 mΩ, 3 W, ±50ppm/°C, operating range -55°C to +170°C); the datasheet prints no pin numbers, terminals are interchangeable. |
