JER2512F3R040

jieerrui · Current Sense Resistors / Shunt Resistors · 2512

JER2512F3R040 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 (R040 = 40mΩ, 1%, 3W rated, small-electrode type with 0.90±0.20mm electrode width); the resistor is non-polarized so the terminals are interchangeable.
2 2 passive Second terminal of the 2512 alloy current-sense resistor (40mΩ, 1%, 3W rated, operating temperature -55°C to +170°C with power derating above 70°C); the resistor is non-polarized so the terminals are interchangeable.
