FOJAN · Current Sense Resistors / Shunt Resistors · 2512

FRM252WJR300TK from FOJAN, 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 alloy current-sense resistor (300mΩ part, Sn-plated terminal); rated 2 W at 70°C, 63 A rated current for the 2512 type.
2 2 passive Second end electrode of the 2512 alloy current-sense resistor; Kelvin four-terminal sensing points (V and A) are on the bottom of each electrode, 5.6±0.25 mm apart (dimension A).
