Littelfuse, Inc. TELELINK® Surge Tolerant Surface Mount Fuse 04611.25

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 standalone Designed to allow compliance with Bellcore/Telcordia GR-1089-CORE and FCC 47 part 68 Surge Specifications Provides coordinated protection with Littelfuse SIDACtor® devices. 2 A rating has improved temperature rise performance under 2.2 A surge current testing
