The new Raychem Circuit Protection PolySwitch TSM600-250 is a surface-mount device that provides tandem resettable overcurrent circuit protection. It is targeted for use in DSL and other telecommunications network equipment, including high-density multi-port linecards. The TMS600-250 incorporates two matched, low-resistance PPTC (polymeric positive temperature coefficient) components into a single device to yield balanced protection on tip-and-ring lines with minimal attenuation of data transmission. In addition to interrupting ac power faults, the robust device meets Telcordia GR-1089 lightning-related safety specs. Pricing starts at $0.80/100K.
