The SFF 8639 SMT Type Flush Mount Male Connector, also known as a U.2 PCIe NVMe male connector, is a high-density, surface-mount interconnect designed for enterprise storage systems, servers, and high-performance computing platforms. Compliant with the SFF-8639 (U.2) standard, this connector supports PCIe Gen3 and Gen4 NVMe SSDs, delivering high-speed Data Transmission up to 32 Gbps with stable Signal Integrity. Its SMT flush-mount structure allows the connector to be mounted level with the PCB surface, reducing overall system height while improving mechanical stability and assembly efficiency in dense, space-constrAIned designs. Manufactured with flame-retardant thermoplastic housing and precision gold-plated contacts, the connector ensures low Contact Resistance, corrosion resistance, and long-term reliability across repeated mating cycles.
