The third set of user inputs is titled Characteristics of Fixed Resistors. For the fixed resistor network, the user has some degrees of freedom, but the mechanical execution has been restricted to one of VISHAY’s thin film high stability precision resistors, namely the TNPW series. Within this series, the user can first select the preferred case size. Secondly, the user must select the desired E-series option. Depending on which E-series is chosen, the program will select the most approaching values within the chosen series. Selecting E192 will more closely approach the computed values than lower E-series options. Additionally, the resistance tolerance and Temperature Coefficient of Resistance must be chosen. These selections are explained in more detail on the next page.
