Isabellenhütte SMP Series

The SMP 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 has a resistance range of 0.005Ω to 1Ω, TC of below 50 ppm/°C over the temperature range of +20°C to +60°C and offers excellent long term stability. The SMP model offers these capabilities in a 2010 chip size.
