HoLRMC2512-2W-1mR-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 plated end terminal of the 2512 alloy current-sense resistor (1 mΩ, 1%, 2 W at 70℃, max rated current 44A); the part is non-polarized and interchangeable with the other terminal. |
| 2 | 2 | passive | Second plated end terminal of the 2512 alloy current-sense resistor (1 mΩ, 1%, 2 W at 70℃, max rated current 44A); the recommended pad is A 4.0 mm, L 4.1 mm, B 2.1 mm with separate sensing traces. |
