TNC COAXIAL CONNECTORS
The Connex TNC connectors are made to a high quality level. Medium size coaxial
connectors with thread coupling. 50 ohm impedance for applications up to 11 GHz and
75 ohm impedance up to 1 GHz. Cable entires full crimp or clamp type with soldered or
crimp center contact.
75 OHM SERIES
Within the internationally standardized TNC mating face dimensions, a perfect 75 ohm
characteristic impedance cannot be realized. However, at frequencies up to 1 GHz, the
small impedance deviation is negligible for practical applications. A typical SWR of 1.15:1
at 1 GHz is achieved.
All 75 ohm TNC connectors and 50 ohm TNC connectors are intermateable.
Note: Silverplated bodies are available by adding “S” to end of part number. Nexcote (white
bronze) plating with no nickel under body or center contact is available by adding
“NEX” to end of part number.
