The RBH ultra-precision current sense resistor series from Alpha Electronics offers low resistances of between 0.01ฮฉ and 1ฮฉ all in a small 4-terminal (Kelvin connection) flip-chip package. By utilising Alphaโs Bulk Metalยฎ foil resistor technology, they are able to offer low tolerances down to ยฑ0.5% as well as a low TCR of ยฑ10 ppm/ยฐC between -25ยฐC and +125ยฐC.
The RBH ultra-precision current sense resistor series offer ultra-precision thanks to Alphaโs Bulk Metalยฎ foil resistor technology, making them suitable for the most demanding precision applications.
Temperature rise of resistor surface can be optimised by using a board made of metal. This keeps the temperature rise very low allowing increased power rating of the parts i.e. 2W at +70ยฐC. Please keep the temperature of board less than +90ยฐC when using glazed epoxy board.
