Get help specifying or customising the right product for your application.
Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
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.
