VPG PE Series

The PE ultra-precision power shunt resistor series from Alpha Electronics offers 4-terminal (Kelvin) connection for current sensing and a power rating of up to 10W on a heat sink or 1.5W in free air (at +70°C) over a resistance range of 0.5Ω to 500Ω. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to offer low temperature coefficients down to ±2.5 ppm/°C between the resistance range 5Ω and 500Ω as well as tight tolerances down to ±0.01% between 25Ω and 500Ω.
