JER2512F3R012

jieerrui · Current Sense Resistors / Shunt Resistors · 2512

JER2512F3R012 from jieerrui, 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 terminal (electrode, E = 0.90±0.20 mm on the small-electrode 2512 body); the 2512 part is rated up to 3 W, and power derates linearly above +70 °C to zero at +170 °C.
2 2 passive Second resistor terminal (electrode, E = 0.90±0.20 mm on the small-electrode 2512 body); the element is non-polarized and the two terminals are interchangeable.
