Description
SMA PCB Connector | End Launch | Brass Body
The ROSNOL SMA2H2A50-0173B/91 is a robust SMA Jack (female) tailored for PCB end launch configurations. It incorporates a screw-lock coupling mechanism with a minimum of 500 mating cycles for secure connectivity. Operating from DC to 18 GHz with a 50 Ω impedance, it provides excellent VSWR ≤1.20 up to 6 GHz and insertion loss ≤ 0.03 × √F (GHz) dB. The connector includes a straight coaxial pin insulated with PTFE for reliable RF performance.The SMA2H2A50-0173B/91 is constructed with a brass body and beryllium copper center contact, plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus. It is designed for end launch mounting and meets MIL-STD standards for thermal shock, vibration, corrosion, and moisture resistance.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
