High Current Terminal EMI Chips
E07
The high current 3 terminal chips are an extension to the Syfer 3
terminal EMI chip range, and are capable of carrying currents up to
2A. Suitable for use on DC lines on pcbs, they can prevent the
radiation of interference emanating from high speed signal lines and
IC’s and also prevent the propagation of high frequency noise on
power lines. Improved high frequency filtering performance is
offered as a result of the DC current being fed directly through the
EMI chip.

Typical performance is shown in the graph above. The actual performance
will be influenced by the amount of series inductance added by the
interconnections.
