Isabellenhütte SMK Series

The SMK current sensing precision resistor series from Isabellenhütte offers the designer higher power ratings and low internal temperature rises due to the larger pad termination sizes. The MANGANIN® alloy resistance element with a resistance range of 0.008Ω to 0.5Ω, has a TC of below 50ppm/°C over the temperature range of between +20°C and +60°C for resistance values of 0.015Ω or more and offers excellent long term stability. The SMK model offers these capabilities in a 1206 chip size.
