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

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.

Helping You Meet
Customer Expectations
Traditional telephone service
has evolved to include
broadband transmission of
data, Internet access and
other converged media.
Customer expectations of
24/7 access, consistent
quality-of-service and high
reliability are now greater
than ever before.
The Littelfuse Solution
In light of these
developments, the need
for circuit protection to
ensure both successful
day-to-day operation and
public safety is also greater
than ever. Today’s copper
plant is exposed to threats
from AC power fault and
lightning induced events.
Unless telecommunications
links are properly protected,
this exposure can lead to
service interruptions or
possible equipment failure.
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.

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.
