PEWF2512F3L00Q9

RESI · Current Sense Resistors / Shunt Resistors · 2512

PEWF2512F3L00Q9 from RESI, 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 copper electrode of the 3 mΩ ±1.0% pure-alloy current-sense resistor (6.3 x 3.0 mm body, rated 3 W per series table), connected to the resistive alloy by electron-beam weld; solder to the recommended pad (a=3.9, b=3.4, c=1.8 mm).
2 2 passive The other copper electrode of the same two-terminal resistor, interchangeable with the first; the part is for DC low-frequency sensing circuits only per the datasheet.
