LRBM25GFER060

NCT · Current Sense Resistors/Shunt Resistors · 2512

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.
