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.
