LRBM25GFER060 from NCT, 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 | One end electrode of the 2512 (6.4x3.2 mm) LRB25* current-sense resistor; non-polarized, 3W rated at 70°C with derating above, 4-wire measurement on the back electrodes. |
| 2 | 2 | passive | Other end electrode of the 2512 LRB25* current-sense resistor; non-polarized and interchangeable with the first terminal, with the 4-wire measurement points 5.60 mm apart. |
