When we think about electrical resistors and their properties, the primary characteristics that come to mind are case size, resistance value, TCR, tolerance, and rated power. For many applications, these characteristics are sufficient to define the resistor that is needed. When it comes to analog precision circuits, however, we need to look deeper at the behavior of the resistors throughout their intended lifetime. For feedback circuits and voltage dividers, the parameters mentioned above, as well as a stable divider ratio, have a decisive impact on the accuracy of the circuit. This application note will explore how the behavior and stability of electronic circuits can be optimized by using thin film chip resistor arrays.
