Twinax Cable:
Withstands
infrared and vapor phase soldering;
Military Temp Range

-55°C to +125°C;
Weight
= 1.0 grams;
Surface Mount
= pick-and-place compatible.
Applications:
Fibre Channel, Gigabit Ethernet, SONET, HDTV, IEEE 1394B, SMTPE.
Application Notes:
These isolation transformers protect the station from static charges that may develop on the cable and prevent ground loop currents from being
transferred between stations. They have also been designed to provide common mode rejection within the transmission band, reducing EMI.
