Effective Series Resistance

Each model in the Modelithics library is based on precise Effective Series Resistance (ESR) measurements taken on individual parts. The empirical data is used to generate a frequency-dependent expression for ESR that is incorporated into the models. The ESR is important in determining the loss factor or Q-factor of low loss circuits such as filters, matching networks and couplers.
