ITU-T/CCITT G703 Mini Balun: (TRUE 75 OHM connectors) Temple Star Inc.
ITU-T/CCITT G.703 Mini Balun
fully shielded design ideal in telecom applications where size and space
are restricted to small dimension. Ideal for panel mounting
or cable mounting and feature IDC termination which allow installation
without special tools. Surface mount transformers inside are replacements
to traditional coaxial, ceramic and printed circuit board baluns.
In addition, conversion to twisted pair cabling enables the use of high density IDC
modules in Digital Distribution Frames (DDF) thus significantly decreasing wiring
densities.
