2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 03/03/17 Surface Mount Fuses Surge Resistant > 461 Series TeleLink Fuse 461 Series TeleLink Fuse Description Agency Approvals Electrical Characteristics for Series Features Surface mount surge resistant Slo-Blo fuse Meet UL 60950 3rd Edition power cross requirements standard alone Designed to allow compliance with Telcordia GR-1089-CORE and TIA- 968-A (formerly FCC Part 68) Surge Specifications Provide coordinated protection with Littelfuse SIDACtor Transient Voltage Suppressor (TVS)or a Greentube TM Gas Plasma Arrestor, without series resistors Designed to serve the requirements of a wide range of telecommunication and networking equipment 2A rating has improved temperature rise performance under 2.2A surge current testing when compared with 1.25A rating Product is Halogen Free and RoHS compliant and compatible with lead- free solder and higher temperature profiles when ordered with Standard Silver Plated Brass Caps Standard product is RoHS Compliant and compatible with lead-free solders and higher temperature profiles RoHS AGENCY AGENCY FILE NUMBER AMPERE RANGE E10480 .5A - 2A 29862 .5A - 2A % of Ampere Rating Opening Time 100% 4 hours, Minimum 250% 1 sec., Min.; 120 secs., Max. The Littelfuse 461 Series TeleLink Surface Mount, Surge Resistant Fuse, offers over-current protection for a wide range of telecom applications without requiring a series resistor. When used in conjunction with a Littelfuse SIDACtor Transient Voltage Suppressor (TVS) or a Greentube TM Gas Plasma Arrestor, this combination provides a compliant solution for standards and recommendations such as GR-1089-Core, TIA-968-A, UL/ EN/IEC 60950, and ITU K.20 and K.21. The coordination requirement contained in GR-1089-Core, and ITU K.20/21 may require a series of impedance devices. Applications T1/E1/J1 and HDSL2/4 SLIC interface portion of Fiber to the Curb (FTTC) and Fiber to the Premises (FTTP) Non-Fiber SLIC interface for Central Office (CO) locations and Remote Terminals (RT) xDSL applications such as ADSL, ADSL2+, VDSL, and VDSL2+ Ethernet 10/100/1000BaseT POTS applications such as modems, answering machines, telephones, fax machines, and security systems ISDN "U" interface Baystation T1/E1/J1, T3 (DS3) trunk cards Telecom Nano 2 Fuse Temperature Reading 04611.25 < 82C (180F) 0461002. < 50C (122F) Maximum Temperature Rise Higher Currents and PCB layout designs can affect this parameter. Readings are measured at rated current after temperature stabilizes. Specifications are subject to change without notice. Application testing is strongly recommended.
