JER2512F3R2R5L

jieerrui · Current Sense Resistors / Shunt Resistors · 2512

JER2512F3R2R5L 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 terminal of the 2512 alloy current-sense resistor (6.40±0.20 mm long body, 3.20±0.20 mm wide, 3W rated power, operating range -55°C to +170°C, power derated above 70°C).
2 2 passive Second terminal of the 2512 alloy current-sense resistor, interchangeable with the first (electrode width 2.20±0.20 mm for large electrode or 0.90±0.20 mm for small electrode).
