JingCheng SMA Female to TNC Female 4-Hole Flange Adapter

Product Code




The SMA "SubMiniature A" connector series is one of the most commonly used RF connector due to its durability and performance. SMA series has a 1/4 - 36 UNS threaded coupling and can operate up to 18 GHz when using semi-flex or semi-rigid cable types.


"Threaded Neill-Concelman". Designed as a screw-on version of BNC connector, TNC connectors have a 7/16 - 28 UNEF threaded coupling providing excellent vibration handling. Widely used due to electrical performance and mechanical durability. TNC series has a characteristic impedance of 50 Ω, however it is important to note that 75 Ω variations while uncommon do exist and are identifiable by the reduced amount of dielectric inside the interface.
