461 Series - TELELINK® Surge Tolerant Surface Mount Fuse
Brand: Littelfuse, IncThe 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 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 of impedance devices.
