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

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.
