| Raychem FT600 Series Overcurrent Fuse New surface-mount fuse products for overcurrent protection of communications equipment Benefits: * When combined with a SiBarTM overvoltage 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 Features: * The lightning robust surface-mount fuse offers overcurrent protection from power faults * Designed to assist equipment in complying with telecom specifications including UL60950, FCC Part 68, and Telcordia GR-1089 * Small footprint and low resistance * Low profile 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 Interrupt Voltage and Current Ratings Part Number FT600-0500 FT600-1250 FT600-2000 Ampere Rating (A) 0.50 1.25 2.00 Voltage Rating (V) 250 250 250 Typical Resistance () 0.5 0.1 0.05 Typical I2t (A2s)* 1 16 18 The FTxxxx devices are designed to carry 100% of rated current for 4 hours minimum and 250% of rated current for 1 second minimum, 120 seconds maximum. Resistance measured at 10% of rated current. *I2t is calculated at 10 ms or less. Power Cross GR-1089 1000Vac, 5A, 0.5sec FT600-0500 FT600-1250 FT600-2000 GR-1089 600Vac, 60A, 5sec UL60950 600Vac, 40A, 1.5sec GR-1089/UL60950 600Vac, 7A, 5sec GR-1089/UL60950 600Vac, 2.2A, 30min GR-1089 277Vac, 25A, 15min UL60950 120Vac, 25A, 30min Note: FT600-1250 and FT600-2000 are designed to assist equipment in complying with Telcordia GR-1089 specifications. In-circuit testing is strongly recommended.
