FT600-2000-2

The telecom FT600 fuse helps telecommunications equipment manufacturers comply with North American overcurrent protection requirements, including Telcordia GR-1089, TIA-968-A (formerly FCC Part 68), and UL60950 3rd edition. TE Circuit Protection’s telecom fuses offer low temperature-rise performance under sneak current fault events to help prevent damage to circuit traces or multilayer boards, and their low profile and small Surface-mount Fuses – Telecom Fuses Surface-mount Fuses Telecom Fuses footprint make them suitable for high-density and space-constrained applications. Benefits Features • High density placement in multi-port system designs • Lead free materials and RoHS compliant • Improved temperature rise performance over other similar surface-mount fuse devices under sneak current testing • Halogen free • The FT600, in conjunction with a thyristor surge suppression device, assists designers to meet regulatory standards without additional series components (refers to: Brⱕ900ppm, Clⱕ900ppm, Br+Clⱕ1500ppm) 11 • Low profile and small footprint • The lightning robust surface-mount fuse offers overcurrent protection in case of power fault events • Enables the design of equipment complying with applicable telecom specifications including UL60950, TIA-968-A, and Telcordia GR-1089 • Low resistance Applications • ADSL, ADSL2, ADSL2plus, SHDSL, VDSL linecards and modems • T1/E1 systems • Twisted-pair telecom ports requiring Telcordia GR-1089, UL60950 and FCC Part TIA-968-A compliance 103 Protection Application Guide for Telecommunications and Networking Devices To use this guide, follow the steps below: 1.

TE Circuit Protection welcomes our customers’ input for additional application ideas for overcurrent protection of telecom applications. Agency Specification/Selection Guide for FT600 Devices Use the guide below to select FT600 devices appropriate for use in your application. The following pages contain specifications for part numbers recommended below. FT600 devices enable telecommunication equipment to meet the applicable protection requirements of these industry specifications. Refer to individual agency specifications for test procedures and circuit schematics. Users should independently evaluate the suitability of, and test each product for their application. Family Product Lightning Power Cross FT600 FT600-0500 TIA-968-A – Types A & B UL60950, 3rd Ed. – 600VAC, 40A FT600-1250 Telcordia GR-1089 – Level 1 and 2 Telcordia GR-1089 – 600 VAC, 40A FT600-2000 TIA-968-A UL60950 Notes: FT600-1250 and FT600-2000 assist equipment in complying with Telcordia GR-1089 specifications. In-circuit testing is strongly recommended. The FT600-0500, FT600-1250 and FT600-2000 help meet the UL60950 Power Cross and FCC TIA-968-A 68 lightning surge requirements. Note that Type A tests allow for an overcurrent protection component to fuse open during the surge. 11 Table FT1 Interrupt Voltage and Current Ratings for FT600 Devices Typical I2t (A2s)* Ampere Rating (A) Voltage Rating (V) Typical Resistance (Ω) FT600-0500 0.50 250 0.50 1 FT600-1250 1.25 250 0.10 16 FT600-2000 2.00 250 0.05 18 Part Number Note: The FT600-xxxx devices carry 100% of rated current for 4 hours minimum and 250% of rated current for 1 second minimum, 120 seconds maximum.
