TNC COAXIAL CONNECTORS

95

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.
