Description
SMB Jack (Female) PCB Connector | Through Hole | 5.08 mm Hole Spacing | Brass Body
The ROSNOL SMB2I50-1143A/11 is a 50 Ω SMB Jack (Female) connector designed for through-hole PCB mounting with 5.08 mm (0.200 inch) hole spacing. It operates from DC to 4 GHz with a VSWR of ≤ 1.30 and insertion loss ≤ 0.1 × √f (GHz), ensuring stable RF signal performance. The SMB interface features a snap-on coupling mechanism that allows quick connection and disconnection, making it ideal for applications requiring fast assembly and moderate-frequency performance. Its compact size and reliable mating characteristics support efficient PCB integration.
This connector is constructed with a brass body and center contact, both gold plated over non-magnetic nickel-phosphorus underplating, ensuring excellent electrical conductivity and corrosion resistance. PTFE insulators provide stable dielectric properties across the operating frequency range. Brass construction offers good machinability and cost efficiency, while gold plating improves long-term signal reliability and contact durability.
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.
