This family of telecommunication and networking
devices was initially designed to 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 defined in ITU, Telcordia GR1089, and
UL60950. Available in chip, surface-mount, and radial-
leaded configurations, TE’s PolySwitch devices help
improve the reliability of customer premise and network
equipment world wide.
