PolySwitch Resettable Devices
Telecommunications and Networking Devices
The PolySwitch families of telecommunications and
networking devices help meet the growing demand
for resettable overcurrent protection. These product
families help provide protection against damage caused
by power cross and power induction surges as dened
in ITU, Telcordia GR1089 and UL60950. Available in
chip, surface-mount and radial-leaded congurations,
TEs PolySwitch devices help improve the reliability of
customer premise and network equipment worldwide.
