• Surface mount surge resistant Slo-Blo fuse.
• Meets UL 60950 3rd Edition power cross requirements stand
alone.
• Designed to allow compliance with Telcordia GR-1089-CORE
and TIA-968-A (formerly FCC Part 68) Surge Specifications.
• Provides coordinated protection with Littelfuse SIDACtor®
Protection Thyristors without series resistors.
• Ideal for use in telecommunication equipment including line
cards, modems, fax machines, phones, answering machines,
caller ID devices and other products connected to phone
network.
• 2A rating has improved temperature rise performance under
Reference Dimensions:
2.2A surge current testing when compared with 1.25A rating.
• Product is RoHS Compliant and compatible with lead-free
solders and higher temperature profiles when ordered with
Standard Silver Plated Brass Caps.

Notes:
1 I2t is calculated at 10 msec or less. I2t at 10 times rated current has a typical value of:
24 A2sec (2.0A), 22 A2sec (1.25A), 1.3 A2sec (0.5A).
• Typical inductance < 40nH up to 500 MHz.
• Resistance changes 0.5% for every ˚C.
• Resistance is measured at 10% rated current.

Selection of test number depends on current limiting & fire enclosure/spacing of
end product
• 26 AWG line cord removes L1/M1 test requirement
• L5 conducted only if product does not pass section 6.1.2
• L2,M2,L3,M3,L4,M4 conducted if not in a fire enclosure
Fuse must open before the wiring simulator fuse (MDL 2.0).
