LRBM25GFER050 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 | First terminal (electrode) of the 2512 current-sense resistor, 6.4±0.2 x 3.2±0.2 mm body, rated 3W maximum at 70°C with derating above, operating range -55 to +170°C. |
| 2 | 2 | passive | Second terminal (electrode) of the 2512 current-sense resistor, interchangeable with the first; resistance is measured 4-wire across the electrodes and the part has a maximum rated current of 38.73 A for LRB25* 3W 2~100 mΩ. |
