HoCG251231m50F4 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 electrode of the 2512 (6.4±0.2 x 3.2±0.2 mm) metal alloy current-sense resistor, 0.5 mΩ ±1% in this MPN, non-polarized and interchangeable with the other terminal. |
| 2 | 2 | passive | Second end electrode of the 2512 (6.4±0.2 x 3.2±0.2 mm) metal alloy current-sense resistor, 0.5 mΩ ±1% in this MPN, non-polarized and interchangeable with the other terminal. |
