Сажетак:	This paper presents how electrical characteristics of ferrite EMI suppressors depend on the operating frequency and temperature. These multi-layer surface-mounted components consist of conductive platinum layer embedded in the middle of nickel-zinc ferrite monolithic structure. In order to analyze variation of performances with temperature changes, a simulation tool has been developed to predict behavior of the SMD ferrite components for EMI suppression. Results for the impedance and inductance as a function of frequency in the temperature range from +25 °C to +120 °C are presented. Proposed EMI suppressors were experimentally tested in the frequency range 1 MHz-1 GHz using an Agilent 4191A RF Impedance analyzer. The calculated results were in very good agreement with the measured ones. © 2008 Elsevier Ltd. All rights reserved.
