9.7 Magnetics Selection Guide

•

Refer to the following tables 9-1 and 9-2 for

10/100M magnetic sources and specification

requirements. The magnetics which meets these

requirements are available from a variety of

magnetic manufacturers. Designers should test

and qualify all magnetic specifications before

using them in an application. The magnetics

listed

the

following

tables

are electrical

equivalents, but may not be pin-to-pin equivalents.
