This document reports on the modeling of a magnetic core component. It provides the part number, manufacturer, and descriptions of the Pspice model used to simulate the hysteresis curve characteristics. Simulation results are presented in graphs and a comparison table shows good agreement between measured and simulated magnetic flux density values with most errors under 1%.
