Advantages
of CTS Solid Ceramic Resistor Networks
CTS "Solid Ceramic"
resistor networks have been manufactured since 1963. These
resistor netorks have the excellent performance characteristics
and proven reliability that makes CTS the resistor network
industry leader. The solid ceramic construction
is even more advantageous for surface mounting. Resistor
networks are exposed to temperature extremes during manufacturing
and to aggressive cleaning procedures thereafter. There are no
material interfaces to permit the entry of harmful liquids with
the CTS one piece ceramic body.
CTS solid ceramic
"SM" networks provide several distinct performance
advantages over molded network constructions.
Metal migration, commonly called dendrite
growth, is a classic cause of internal shorting in electronic
devices when silver and/or lead are present. The mechanism for
dendrite growth includes a voltage potential between metal
electrodes and the presence of moisture. Failure occurs after
moisture penetrates the body of a molded network during the
thermal shock of soldering and the aqueous cleaning process.
Because it does not include a plastic molded outer package, the
CTS solid ceramic construction will not support
internal dendrite growth.
CTS solid ceramic resistor networks offer approximately
60% more internal surface area for resistor network design than comparably sized
molded networks. This extra design space allows CTS to provide many custom
circuit designs that are not possible with molded networks.
