288-Pin DDR4 DIMM Socket – Board-Mount Fit
The 10145891-0320J13LF: This is a 288-position DDR4 SDRAM DIMM connector from Amphenol ICC (FCI), designed for surface-mount attachment to the motherboard. The connector includes latches on each side to lock the DIMM in place and solder retention features that hold the socket down during reflow. The mounting feature is standard top-mount — the DIMM sits perpendicular to the board, which is the normal orientation for DDR4 memory slots.
Standards and Package
The connector conforms to MO-309, the industry-standard outline for DDR4 DIMM sockets. It ships in a tray — the package type used for automated pick-and-place assembly.
