Applications

The SMT 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 0.004Ω to 4.7Ω, TCR of <50 ppm/°C for values ≥0.010Ω and <100 ppm/°C for values <0.010Ω (between +20°C and +60°C) and offers excellent long term stability. The SMT model offers these capabilities in a 2817 chip size.
