TELECOMMUNICATION CIRCUIT PROTECTION SOLUTIONS Offering overvoltage and overcurrent solutions including Teccor ® Protection Thyristors Circuit protection solutions from the technology leader The Protection You Need to Keep People Connected. 2 Littelfuse develops innovative solutions that protect telecom circuits and equipment from overcurrent and overvoltage. We help turn networks into reliable communication systems. 3 Telecommunication Circuit Protection Protecting Today’s More Vulnerable Networks Today's telecommunication networks continue to push an increasing amount of solid state equipment outside the central office into vaults, cabinets, pedestals and onto customer premises. These sensitive, outside plant locations increase the network’s exposure to lightning-induced transients and power fault hazards. Circuit protection solutions from the technology leader 4 Littelfuse offers telecom equipment manufacturers and network operators circuit protection solutions for applications ranging from power distribution, POTS (Plain Old Telephone System), ISDN (Integrated Services Digital Network), xDSL (Digital Subscriber Line) and T1/E1/J1 to Ethernet, FTTC (Fiber to the Curb), FTTH (Fiber to the House) and more. Meeting and Exceeding Regulatory Requirements Our products are robust enough for primary and secondary protection within the central office and transmission stations and sensitive enough for chipset protection. Next Generation Protection Technology Littelfuse circuit protection technologies for telecom include the latest innovations in PCB mount and power fuses, gas plasma (improved GDT) for very robust environmental and high frequency applications, as well as fast switching, solid-state technology such as our Teccor ® brand SIDACtor ® and Battrax™ devices for PCB protection. We provide a single source for solutions that protect against both overcurrent and overvoltage threats. To meet regulatory requirements, telecom equipment must survive a wide range of defined events. Littelfuse participates in several standards organizations to ensure up-to-date knowledge of TIA-968-A, GR-1089-CORE, ITU-T K.20, K.21 and K.44 as well as UL 60950 and other applicable standards. This ensures that Littelfuse can remain on the leading edge of technology development to meet the current and future needs of our customers.

Regardless of your location around the globe, Littelfuse has the circuit protection solution to help your telecommunication equipment comply with applicable industry Regulations, Recommendations, and Standards. Our telecom application experts are dedicated to helping you with your design and testing to ensure you receive a telecommunications protection solution compliant to your precise needs. Littelfuse was the very first U.S. fuse manufacturer to attain ISO 9001 certification. We have been awarded ISO and other quality certifications for our facilities around the world, ensuring the utmost in reliability. 5 Littelfuse-The Leader In Telecommunication Protection Serving Telecommunications Engineers with Teccor® Solutions Founded in 1964 as Electronic Controls Corporation, Teccor products included lighting controls and motor speed controls. To provide the highest quality product, Teccor began to design and make its own thyristors. Soon after, Teccor chose to concentrate on discrete thyristor components, leaving the manufacture of the assemblies to its customers. Circuit protection solutions from In 2003, Teccor was acquired by Littelfuse, Inc. and today lives on as the most recognized brand in telecom overvoltage circuit protection. Teccor products are renowned for high quality and high reliability. Thanks to patented technology and superior silicon designs, Teccor thyristors can withstand high surge currents making them the most durable thyristors on the market today. SIDACtor® Devices: Fast, Stable, Reliable and Cost Effective Teccor SIDACtor protection thyristors are the fastest, most stable, reliable and cost effective solution for protecting telecommunications equipment from hazardous transient voltages. In telecommunications products, which must pass regulatory requirements, SIDACtor devices are connected across tip and ring and from tip and ring to ground, typically behind a current-limiting device such as a surge tolerant TeleLink® fuse. the technology leader Overvoltage Protection Overcurrent Protection Metal Oxide Varistors Gas Plasma (improved GDTs) TVS Diodes PulseGuard® Polymeric ESD Suppressors Teccor ® Protection Thyristors 8 Surge Tolerant Electronic Fuses SOLUTIONS FOR TELECOM TeleGARD™ Power Fuses Innovative Solutions Designed to Your Specifications Littelfuse offers a wide range of protection technologies to meet the circuit protection requirements of telecommunication circuit designers around the world.
