Vertical DDR4 DIMM sockets from FCI provide 288 contacts on 0.85mm pitch and are designed to accept DDR4 memory modules that conform to JEDEC MO-309. The sockets facilitate convenient memory expansion in servers, workstations, desktop PCs, and embedded applications in communications and industrial equipment. The low-resistance contacts also support the use of RDIMM (registered DIMM), which helps to further reduce power consumption in datacenter hardware such as servers, storage and networking equipment. The low 2.4mm module seating plane and slim ejector designs reduce the overall profile of the connector and installed module to help optimize airflow. Surface-mount (SMT), plated-through-hole (PTH) solder, and press-fit (PF) connector termination options are offered.
