Current Sensing Precision Resistor

The CMS current sensing precision resistor series from Isabellenhütte has been developed to offer an outstanding price to performance ratio. This resistor series offers a resistance range of 0.01Ω to 0.5Ω with a temperature coefficient of below 50ppm/°C between (+20°C and +60°C) over the entire ohmic range, tolerances down to ±1% as well as excellent long term stability. The CMS model offers these capabilities in a 2512 chip size.
