Description
Developed in the late 1950s, TNC is a threaded version
of the BNC. TNC stands for Threaded Neill Concelman
and is named after Amphenol engineer Carl
Concelman. This series features screw threads for
mating. TNC are miniature, threaded weatherproof
units with a constant 50 ohm impedance and
operate from 0-11 GHz.
There are two families of TNC connectors:
Standard
Reverse Polarity
They are an ideal choice for use in cellular and
mobile communications, and test and measurement
equipment. They are also widely used in airframe,
aerospace and radar applications where extreme
vibration is a factor.
Cable connectors range from RG6 to RG179 and
include LMR low loss cable.
Features/Benefits
Threaded coupling interface ensures connector
will not decouple in vibration-intensive
applications.
Many TNC connectors are recognized under
the component program of Underwriter’s
Laboratories and have undergone stringent
testing from an independent laboratory.
Performance from 0-11 GHz operates in
many applications.
