HoLR2512D-24mR-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 Ni/Sn-plated end terminal of the 2512D alloy-plate resistor (0.85±0.25 mm terminal length C for 5mR~62mR); rated 3W, max rated current 109.54A (the datasheet lists 109.54A and 118.32A) for the 3W range. |
| 2 | 2 | passive | Second Ni/Sn-plated end terminal of the 2512D alloy-plate resistor, interchangeable with the first because the part is non-polarised; operating temperature -55℃ to +170℃. |
