Description
SMA Plug (Male) to Precision TNC Jack (Female) | Straight Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1PCT25B/933-93 adapter delivers dependable RF performance with 50 Ω impedance and DC–18 GHz frequency range. It achieves VSWR ≤ 1.20 (≥ 20.8 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Contact resistance is ≤ 3.0 mΩ (SMA) and ≤ 1.5 mΩ (TNC), while outer contact resistance is ≤ 2.0 mΩ and ≤ 1.0 mΩ respectively. Rated for 1000 V rms test voltage and 480 V rms working voltage, it ensures RF leakage ≥ 90 dB up to 1 GHz. Mechanical integrity includes 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, complemented by silicone rubber gaskets for environmental sealing. Dimensions include overall length 26.75 mm[1.053 in], hex sizes 8 mm [.315 in] and 12 mm [.472 in], and thread 7/16-28 UNEF-2A.
