Molex's DDR3 DIMM sockets ready for high-density apps
Keywords:Molex? DIMM sockets? DDR3?
The company's DDR3 DIMM sockets feature a lower seating plane than standard designs, enabling the use of very low-profile modules with maximum seating heights below 2.80mm in ATCA blade systems. The new DDR3 DIMM sockets 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 DDR3 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 2.40mm seating plane optimises vertical space for more flexible socket module design heights. Aerodynamic DDR3 DIMM sockets are available in very low profile press-fit (14.26mm), low profile press-fit (22.03mm), low profile SMT (21.34mm) and very low profile SMT (14.20mm) 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 1.10mm. The sockets provide up to 20.23mm 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 21.33mm from side one of the front board PCB. 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.
