Abstract

A practical approach for lumped-parameter circuit modeling of SMT ferrite beads is introduced. Vector Network Analyzer (VNA) measurements are utilized to provide the frequency-dependent characteristics for SPICE analysis. The measured data is imported into the simulation environment via Analog Behavioral Models (ABM) accounting for the frequency-dependent behavior of the ferrite sheets. It demonstrates a significant departure from a simple R-L-C circuit network. Model accuracy is validated by realization of an ad hoc test-board and by experimental characterization of the component in terms of Insertion Loss.
