LTE dielectric—high speed, low loss, light weight.

Thermax LTE is a patented extruded expanded low-density PTFE dielectric offering multiple advantages,

not only over solid PTFE, but other air-spaced constructions as well.

Unlike closed-cell foam, perforated-tape, or ﬁlament / air-spaced types, LTE does not lose mechanical strength

at high percentages of air. In fact, LTE maintains structural integrity at up to 70% air by volume. Because the air

is introduced into the PTFE during the extrusion process, LTE has a homogenous dispersion of air within its

structure, providing highly-consistent performance from lot to lot and within a length of cable.

Other advantages of LTE construction include:

• 50Ω, 75Ω, and 95Ω impedance standard; other impedances available.

• Lower capacitance at all impedances.

• Lower attenuation.

• 260˚ C temperature rating, with stable performance at elevated temperatures.

• Enhanced cable ﬂexibility.

• High-performance replacements for MIL-C-17 cables such as RG-142, 179, 393, and 400.

• Twinaxial types, both parallel and twisted pair.

See page 4 for 100 Base-T Ethernet cables with LTE insulation; page 14 for twinaxial and high-speed

miniature cables with LTE dielectrics; and page 17 for coaxial LTE cables. Other cable types are also

available with LTE dielectrics; just contact your Thermax representative with your requirements.
