DDR3 DIMM memory sockets
18 September 2013
Interconnection
Molex has introduced a portfolio of aerodynamic DDR3 DIMM sockets and ultra-low profile DDR3 DIMM memory module sockets, both of which are ideal for demanding memory applications in telecommunication, networking and storage systems, advanced computing platforms, industrial controls and medical equipment.
The new sockets feature a lower seating plane than standard designs, enabling the use of very low-profile modules with maximum seating heights below 2,80 mm in ATCA blade systems. They also feature low-level contact resistance of 10 milliohms to support the use of registered DIMM modules and reduce power consumption in blade servers.
The aerodynamic DIMM sockets feature a streamlined housing and latch design to maximise airflow and eliminate trapped hot air during operation. The ergonomic latches enable quick actuation and easy removal of high-density memory modules. The low 2,40 mm seating plane optimises vertical space for more flexible socket module design heights.
Aerodynamic DDR3 DIMM sockets are available in very low profile press-fit (14,26 mm), low profile press-fit (22,03 mm), low profile SMT (21,34 mm) and very low profile SMT (14,20 mm) heights. The press-fit sockets feature smaller eye-of-needle compliant pins than standard press-fit terminals to free up valuable PCB real estate for higher-density trace routing. All Molex aerodynamic DDR3 DIMM sockets are RoHS compliant and SMT versions are halogen-free.
Molex ultra-low profile DDR3 DIMM sockets feature a seating plane of only 1,10 mm. The sockets provide up to 20,23 mm of vertical space above the PCB for mounting high-density DIMMs and are ideal for applications requiring conformance to ATCA board mechanics specifications where component heights cannot exceed 21,33 mm from side one of the front board PCB.
The ultra-low profile DDR3 DIMM sockets also feature reduced latch-actuation angles, which use less PCB real estate than standard DIMM sockets to improve airflow and enable more adjacent components. The new halogen-free sockets have a glass-filled, high-temperature nylon housing and latches to enable wave soldering and high-temperature infrared reflow operations.
