| 103 ? 2009 littelfuse, inc. specifications are subject to change without notice. surface mount fuses 159 series 159 fuse and clip series please refer to www.littelfuse.com/series/159.html for current information. 159 series 159 series telelink ? fuse and clip assembly description agency approvals electrical characteristics for series features % of ampere rating opening time 100% 4 hours, minimum 250% 1 sec., minimum 120 secs., maximum agency agency file number ampere range e14721 0.5a, 1.25a, 2.0a the 159 series product is a metal fuse clip with pre- installed littelfuse 461 series telelink ? 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-1089- core and tia-968-a surge specifications. the product provides coordinated protection with littelfuse sidactor ?
