YHR2512SE2WR210F4

Yohey · Current Sense Resistors / Shunt Resistors · 2512

YHR2512SE2WR210F4 from Yohey, 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 resistor electrode of the 2512 SE (short electrode, E 1.0±0.2 mm) alloy current-sense resistor; the pad drawing shows a separate sensing trace for Kelvin connection, and the part is non-polarized.
2 2 passive Second resistor electrode of the 2512 SE (short electrode, E 1.0±0.2 mm) alloy current-sense resistor; the pad drawing shows a separate sensing trace for Kelvin connection, and the part is non-polarized.
