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

TNC Plug (Male) to SMA Jack (Female) Adapter | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-PCT1A25B/9XX-9X is a precision RF adapter designed for DC to 18 GHz operation with 50 Ω impedance, VSWR ≤ 1.2 (≥20.8 dB return loss), and insertion loss ≤ 0.1√f (GHz) dB. It offers excellent electrical performance with insulation resistance ≥5 GΩ, center contact resistance ≤1.5 mΩ (TNC) and ≤3.0 mΩ (SMA), and outer contact resistance ≤1.0 mΩ (TNC) and ≤2.0 mΩ (SMA). Working voltage is rated at 480 V rms, dielectric withstanding voltage at 1000 V rms, and RF high-potential at 670 V rms. The screw-lock coupling mechanism ensures secure engagement, with center contact captivation ≥27 N, mechanical durability of ≥500 mating cycles, and recommended torque of 0.46–0.69 Nm (TNC) and 0.8–1.1 Nm (SMA).

Constructed with beryllium copper center contacts plated with gold over nickel-phosphorus underplating, stainless steel bodies and coupling nuts with passivation, and PTFE insulators for stable dielectric properties. The adapter operates reliably across −65°C to +160°C, ensuring durability in extreme environments.

ROSNOL’s RF adapters are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. They provide a cost-effective alternative to leading global brands, combining high quality with competitive pricing. Customization services for materials, plating, and mechanical design are available to meet specialized requirements.
