SMA Jack (Female) Straight Connector 4 Hole Flange, Hermetic sealed Stub Terminal, 8.64mm (.340 inch) DC-18GHz VSWR1.30

SMA Jack (Female) | Solder Attachment | 4 Hole Flange | Stainless steel Body| Hermetic sealed

The ROSNOL HS‑SMA2GFA50‑1839A/9Q is an SMA Jack (Female) connector designed for solder attachment and 4‑hole flange mounting with an 8.64 mm (.340 in) hole spacing. Featuring a hermetic glass‑to‑metal seal and supporting RF performance from DC to 18 GHz, the connector provides 50‑ohm impedance, ≤1.30 VSWR, high insulation resistance, and a 1000 V rms test voltage rating. The screw‑lock interface supports at least 500 mating cycles, while the captivated stub‑terminal center contact ensures ≥27 N axial retention for mechanical reliability.

The connector incorporates a beryllium copper center contact with gold plating over a non‑magnetic nickel‑phosphorus underplating for excellent conductivity and corrosion resistance. Its stainless‑steel body is gold‑plated for durability, while the hermetic seal utilizes Kovar contact pins and Corning 7070 glass for robust environmental sealing. A PTFE insulator maintains stable dielectric performance across wide temperature variations. These materials make the HS‑SMA2GFA50‑1839A/9Q suitable for hermetically sealed RF modules, microwave systems, and high‑reliability communication hardware.
