Description
General part information
04611.25 Series
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.
