The Littelfuse 461 Series TeleLink® surface mount, surge tolerant 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 GreentubeTM 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 impedance device.


  • RoHS Compliant.
  • Surface mount overcurrent protecting from power cross and allows compliance with lightning surges.
  • Meets UL 60950 3rd Edition (formerly UL 1459) power cross requirements stand alone.
  • Designed to allow compliance with Bellcore/Telcordia GR-1089-CORE and FCC 47 part 68 Surge Specifications.
  • Provides coordinated protection with Littelfuse SIDACtor® devices.
  • Ideal for use in telecommunication equipment including line cards, modems, fax machines, phones, answering machines, caller ID devices and other products connected to phone network.
  • 2A rating has improved temperature rise performance under 2.2A surge current testing.
