DDK DMM-168FLAA2-2A236 Dimm socket for memory expansion Datasheet

DIMM Socket For Memory Expansion
Conforming To JEDEC Standard DMM Series, 168 Contacts
Workstations, Computers, Disk arrays and Servers
FEATURE
●Applicable to 168-position module per JEDEC
standard MO-161
●Board locks which prevent the connector from
lifting during reflow soldering
●Voltage keying design for both 5V and 3.3V
modules
●Available with locking ejector on either side or
both sides of connector
●Insulator molded from surface mount compatible
plastic
●Accepts DRAM, SDRAM and non-standard
DRAM module
●Straight plug in design minimizes bending of
module
●Low insertion force
