Abstract(in English) | Ferrite cores are commonly used to suppress the electromagnetic noise emitted from digital information equip-ment, and also to improve the immunity level against the noise. This is largely because the information of the portion attached by the ferrite core increases with frequencies, resulting from reduction of the high frequency current flowing on that portion. The mechanism, however, is not being theoretically elucidated in relation to the core dimension and material. This paper analyzes the high frequency impedance of the lead produced by the ferrite core attachment, thereby showing the equivalent circuit for the load effect. The dimension design method is given for effectively enhancing the resistive impedance per unit core length. Measurement of the vector impedance is also made to validate the equivalent circuit derived here. |
