RALEC · Current Sense Resistors / Shunt Resistors · 0805

LRE0805-2CR050F5 from RALEC, in a 0805. 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 of the two terminals (MPN code 2 = 2 terminals) of the 0805 metal-alloy low-resistance resistor; the bottom electrode has a current terminal and a voltage terminal measurement point on this end, spaced 1.65±0.05 mm (A) from the other end.
2 2 passive The other terminal of the 2-terminal 0805 resistor, interchangeable with the first terminal; the datasheet gives it a current and a voltage measurement point, with 0.70±0.05 mm (B) between them, and matte Sn plating over Ni.
