Thermal Interface Products are mandatory
for reducing the waste heat and cooling
the system in the most efficient way. Waste
heat reduces the silicon chip reliability and
performance. In addition to the products
Tyco Electronics is offering such as Heat
Sinks, Heat Pipes and CHIP COOLERs,
in all shapes and sizes, Tyco Electronics
offers state of the art Thermal Management
Services. Thermal Management is the
design practice of moving waste heat to
locations that do not affect the equipment or
overall device performance. Each Thermal
Product can be fully customized
to fulfill the specific requested system
cooling requirements.

Tyco Electronics’ MRJ21 receptacle is a
high density I/O interconnect. This high
density connector supports AdvancedMC
Mid-size and Full-size module face plates
and AdvancedTCA face plates. It can also
be used for Rear I/O via Rear Transition
Modules (RTMs), as well as in
AdvancedTCA Zone 3 applications.
The MRJ21 connector is fully shielded and
provides density savings for current 10/100
or GbE RJ45/RJ21 applications. The low
profile and narrow width design will allow
more ports to be packed into less space.
Tyco Electronics offers a full end-user
solution with cleaner cabling solutions over
RJ45s, and patch panels for plug-and-play
environment, including data centers and
zone cabled or open office environments.
