Molex High-Performance Cables
Molex invested strategically years ago in Temp-Flex, a high-
performance cable manufacturer based in South Grafton,
Massachusetts, to provide customers with the best custom
cabling solutions possible.
Temp-Flex produces leading high-performance coaxial
cables that specifically excel in demanding technical
environments. The company offers three distinct cable types,
each with unique velocity of propagation characteristics:
1. Solid PFA - Good Attenuation Their first cable achieves
70% velocity of propagation. It utilizes solid PFA
(perfluoroalkoxy alkane) or a modified Teflon material.
2. Foamed Fluoropolymer - Better Attenuation Their
second cable, employing a foamed fluoropolymer material,
reaches a velocity of propagation of 79%. This design
provides better attenuation and lower signal loss than the
first option.
3. Monofilament PFA—Best Attenuation Their premium
cable boasts an 88% velocity of propagation. This design
incorporates more air into the dielectric core by combining
a filament with a dielectric sleeve.
With the technical and manufacturing expertise available
through Temp-Flex, customers can create cable designs for
applications requiring precise signal timing and minimal losses.
