This document summarizes the modeling of a magnetic core component. It describes the core's parameters, manufacturer, and part number. Simulation results are shown for the core's hysteresis curve, evaluation circuit, and comparisons between measured and simulated magnetic flux densities under varying magnetic fields. The maximum error between measurement and simulation was below 3%.
