Description
SMB Plug (Male) | Solder Cup | 4 Hole Flange Mount | Brass Body
The ROSNOL SMB1GFB50-1750A/H11 is a precision-engineered SMB plug connector designed for secure screw-lock coupling and reliable RF performance. It features a solder cup terminal and a 4-hole flange mount with 8.6 mm (0.340 inch) hole spacing. Electrical specifications include 50 Ω impedance, DC to 4 GHz frequency range, VSWR ≤ 1.22 (≥ 20 dB return loss), and insertion loss ≤ 0.1√f (GHz) dB. The connector supports a working voltage of 250 V rms at sea level, insulation resistance ≥ 1 GΩ, and RF leakage ≥ 55 dB up to 1 GHz. Mechanical durability is ensured with ≥ 500 mating cycles, engagement force ≥ 63 N, and axial captivation ≥ 10 N.Constructed from high-quality materials, the center contact and body are made of brass with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, ensuring excellent conductivity and corrosion resistance. The insulator is PTFE for superior dielectric performance. The soldered center contact and captivated design provide robust mechanical integrity for demanding environments.
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.
