*Bold face items in the tables above represent the package without the external thermal system.
The Cauer networks generally have physical significance
and may be divided between nodes to separate thermal
behavior due to one portion of the network from another.
tools, whereas Foster networks may be more easily
implemented using mathematical tools (for instance, in a
spreadsheet program), according to the following formula:
S 1 Ri 1 ? e ? t taui
The Foster networks, though when sorted by time constant
(as above) bear a rough correlation with the Cauer networks,
are really only convenient mathematical models. Cauer
networks can be easily implemented using circuit simulating
