Pulse BNC(F) Connector; Square Flange - Solder Pot
BNC connectors are similar to the TNC series but instead of a thread they use a bayonet coupling mechanism allowing a quicker connect/disconnect. BNC connectors are generally used within an operating range of DC to 4 GHz and are popular with many wireless applications requiring frequent connection and disconnection such as test equipment. Also available in reverse gender versions. * All listed BNC connectors feature the standard 50 Ohm interface dimensions. 75 Ohm interface dimensional connectors and an expanded range of other BNC connectors are available.
