0461 Series TeleLink? SMF

The Littelfuse 461 Series TeleLink? Surface Mount,Surge Resistant Fuse.

  • Brand: Littelfuse
  • Classification: SMD Fuse
  • Voltage: 600V
  • Current: 0.5A-2A
Description:

 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 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.


Features:

? Surface mount surge resistant Slo-Blo? fuse

? Designed to serve the requirements of a wide range of telecommunication and networking equipment

? Meet UL 60950 3rd Edition power cross requirements standard alone

? 2A rating has improved temperature rise performance under 2.2A surge current testing when compared with 1.25A rating

? Designed to allow compliance with Telcordia GR-1089-CORE and TIA968-A (formerly FCC Part68) Surge Specifications

? Product is Halogen Free and RoHS compliant and compatible with leadfree solder and higher temperature profiles when ordered with Standard Silver Plated Brass Caps

? Provide coordinated protection with Littelfuse SIDACtor? Transient Voltage Suppressor (TVS)or a GreentubeTM Gas Plasma Arrestor, without series resistors

? Standard product is RoHS Compliant and compatible with lead-free solders and higher temperature profiles
