SMA Plug (Male) to Precision TNC Jack (Female) Adapter, DC-18GHz VSWR 1.20

SMA Plug (Male) to Precision TNC Jack (Female) | Straight Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1PCT25A/933-93 adapter provides dependable RF performance with 50 Ω impedance and DC–18 GHz frequency coverage. It offers VSWR ≤ 1.20, insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Contact resistance is ≤ 3.0 mΩ (SMA) and ≤ 1.5 mΩ (Precision TNC), outer contact resistance ≤ 2.0 mΩ and ≤ 1.0 mΩ respectively. Rated for 1000 V rms test voltage and 480 V rms working voltage, it supports RF leakage ≥ 90 dB up to 1 GHz. Mechanical features include screw-lock coupling, axial captivation ≥ 27 N, torque range 0.80–1.10 Nm (SMA) and 0.46–0.69 Nm (TNC), and minimum 500 mating cycles.

The SMA and Precision TNC bodies are brass with nickel plating for corrosion resistance. Center contacts are beryllium copper with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. Insulators are PTFE for both ends, and silicone rubber gaskets provide environmental sealing. Dimensions include overall length 43.8 mm [1.724 in], hex sizes 8 mm [.315 in], 11 mm [.433 in], and 14 mm [.551 in].
