While a wide‐ranging topic, the measurement of passive PC board components is focused on the measurement of surface mount technology (SMT) resistors, SMT capacitors, and SMT inductors. These components comprise the majority of passive elements used in radio circuits and also create some of the most undesirable side effects in circuits because of the nature of their parasitic elements. Here is a review of the models of these elements; during measurement, the difficulty is in understanding the relative importance of aspects of these models and extracting the values of the model elements.
