Description
SMA Female Connector with Stub Terminal | Solder Attachment | Brass Body
The ROSNOL SMA2GTA50-1690A/91 is a high-frequency SMA jack supporting DC to 18 GHz, with ≤1.30 VSWR and ≤0.05√F(GHz) dB insertion loss. It features a stub terminal and 2-hole flange mount with 12.22 mm (.481 inch) spacing for secure soldering. Electrical specs include ≥5 GΩ insulation resistance, ≤3 mΩ center contact resistance, and ≤200 W power handling @ 2 GHz.This connector is built with a brass body and beryllium copper center contact, both plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating. The PTFE insulator ensures excellent dielectric performance across a wide temperature range from -65°C to +165°C. Mechanical durability includes ≥500 mating cycles and torque rating up to 1.7 Nm.
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.
