HoLRS2512-3W-0.25mR-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 terminal (left copper end) of the 0.25 mΩ ±1% bare-alloy current-sense resistor, rated 3 W and 109.54 A, with the other terminal on the opposite end of the body. |
| 2 | 2 | passive | Second terminal (right copper end) of the 0.25 mΩ ±1% bare-alloy current-sense resistor, rated 3 W and 109.54 A, non-polarized and interchangeable with terminal 1. |
