PolySwitch
devices
for
telecommunication
and
networking applications were initially designed over ten
years ago to meet the growing demand for resettable
overcurrent protection. These product families help
provide protection against power cross and power
induction surges as defined in ITU, Telcordia GR1089,
and UL60950. Available in chip, surface-mount, and
radial-leaded configurations, PolySwitch devices help
improve the reliability of customer premise and network
equipment world wide.
