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.

| Series / Model |
Resistance value, in ohms, is expressed by a series of 4 or 5 characters, where the character R (ohms) designates the location of the decimal point.
Due to the technical complexity nature of these components, complete specifications, performance data, dimensional information and configuration options are provided within the product datasheet.
