Littelfuse 461 Cross TeleLink Time Delay Surface Mount Fuse 600V 0.5A 1A 1.25A 2A 1025
Description Of The Littelfuse 461 Cross TeleLink Time Delay Surface Mount Fuse 600V
The 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 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, TIA968-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.
