FT600 Datasheet, PDF (1/2 Pages) Tyco Electronics – New surface-mount fuse products for overcurrent protection of communications equipment

Raychem FT600 Series Overcurrent Fuse
New surface-mount fuse products for overcurrent protection of communications equipment
Benefits:
• When combined with a SiBar™ overvolt-
age protection device, assists equipment
in meeting regulatory standards with no
additional series components
• Improved temperature rise performance
over other similar SMT fuse devices
under sneak current testing
• High density placement in multi-port
system designs
Target Applications:
• xDSL and ADSL linecards and modems
• T1/E1 systems
• Twisted pair telecom ports requiring
Telcordia GR-1089, UL60950 and FCC
Part 68 compliance
Features:
• The lightning robust surface-mount fuse
offers overcurrent protection from power
faults
• Designed to assist equipment in comply-
ing with telecom specifications including
UL60950, FCC Part 68, and Telcordia
GR-1089
• Small footprint and low resistance
• Low profile
