Surface Mount Fuses 159 Fuse and Clip Series 159 Series Telelink(R) Fuse and Clip Assembly RoHS Description The 159 Series product is a metal fuse clip with preinstalled Littelfuse 461 Series TeleLink(R) fuse. This fuse and clip combination can be automatically installed in PC Boards in one efficient manufacturing operation. It permits quick and easy fuse replacement without exposing the PC Board and other components to risks of rework solder heat as required with direct surface mount fuses. It meets UL 60950 power cross requirements and is designed to allow compliance with Telcordia GR-1089CORE and TIA-968-A Surge Specifications. The product provides coordinated protection with Littelfuse SIDACtor(R) protection thyristors without series resistors.
