BOARD/WIRE-TO-BOARD
CONNECTORS
DDR4 MEMORY MODULE SOCKETS
OVERVIEW
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.
FEATURES & BENEFITS
• Sockets provide mechanical voltage keying and
end latches for module retention and ejection
• Low insertion-force design requires less than
24 pounds force for module installation
• Available solder tail options support use on 1.6mm or
2.4mm thick motherboards
• Press-fit termination option supports use on 1.6mm
min. host-PCBs
• Contact design protects against stubbing and
supports high-speed serial differential signaling
at data rates extending to 3.2Gb/s for DDR4
• Low contact resistance supports RDIMM modules
• Slim latch design optimizes airflow
• RoHS-Compliant and lead-free process-compatible
options aid compliance with lead
elimination initiatives
