Description
SMA Jack (Female) | PCB End Launch | Screw-lock | Brass Body
The ROSNOL SMA2H3B50-0100A/91 connector is a precision-engineered SMA Jack (Female) designed for PCB end-launch applications with a straight flat pin and air-space design for optimized high-frequency performance. It operates from DC to 18 GHz with a 50 Ω impedance, delivering VSWR ≤ 1.20 at 6 GHz and ≤ 1.30 at 18 GHz, ensuring excellent return loss. Insertion loss is ≤ 0.03 × √F (GHz) dB, while insulation resistance is ≥ 5 GΩ. Electrical ratings include center contact resistance ≤ 3.0 mΩ, outer contact resistance ≤ 2.0 mΩ, test voltage 1000 V rms, and working voltage 480 V rms. Power handling capability reaches 200 W at 2 GHz and 100 W at 10 GHz, with RF leakage ≤ 100 dB up to 1 GHz.Constructed from premium materials, the center contact is beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. The body is brass with gold plating, and the insulator is PTFE for superior dielectric stability. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, axial captivation ≥ 20 N, radial captivation ≥ 1 Ncm, and torque ratings of 0.8–1.1 Nm recommended (1.7 Nm max).
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 manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global standards. Customization services for plating, materials, and mechanical design are available upon request.
