Description

The CMK current sensing precision resistor series from Isabellenhütte has been developed to offer an outstanding price-performance ratio. With a resistance range of 0.01Ω to 0.1Ω, other specifications include a temperature coefficient of below 50ppm/°C (between +20°C and +60°C) over the entire ohmic range, tolerance options as low as ±1% as well as excellent long term stability. The CMK series offers these capabilities in a 1206 chip size.
