TNC Plug (Male) to SMA Jack (Female) Adapter, DC-11GHz VSWR 1.25

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

The ROSNOL AD‑T1A25A/9XX‑9X is a compact TNC Plug (Male) to SMA Jack (Female) adapter engineered for stable RF performance from DC to 11 GHz. With 50‑ohm impedance, ≤1.25 VSWR, high insulation resistance, and a 1000 V rms test voltage rating, it supports reliable low‑loss transmission for mid‑band RF applications. Both TNC and SMA interfaces use screw‑lock coupling, provide a minimum of 500 mating cycles, and feature 27 N contact captivation for secure mechanical engagement.

The adapter uses beryllium copper center contacts with gold plating over a non‑magnetic nickel‑phosphorus underplating for strong conductivity and corrosion resistance. Stainless‑steel bodies with passivated finishing enhance structural durability, while PTFE insulators ensure stable dielectric performance. A silicone rubber gasket improves environmental sealing on the TNC side. These materials make the AD‑T1A25A/9XX‑9X suitable for RF communication systems, instrumentation, and applications requiring dependable TNC‑to‑SMA connectivity.

ROSNOL’s precision‑engineered solutions provide a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are produced in ISO 9001‑certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services are available to support specialized RF and microwave application requirements.
