JER2512F2R001L

jieerrui · Current Sense Resistors / Shunt Resistors · 2512

JER2512F2R001L 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 One terminal electrode of the 2512 alloy current-sense resistor (1 mΩ, 2 W per part code; electrode width E 2.20±0.20 mm for the large-electrode type); the element is non-polarized so terminals are interchangeable.
2 2 passive Other terminal electrode of the 2512 alloy current-sense resistor (1 mΩ, 2 W per part code; electrode width E 2.20±0.20 mm for the large-electrode type); the element is non-polarized so terminals are interchangeable.
