MM80 Series DDR3 Memory Module Connectors from JAE

DDR3 Memory Module Connectors - MM80 Series from JAE

October 13, 2010

For devices like notebook PCs, servers and fax machines, the data volume has recently been increasing due to the growing use of high-definition video and images. This has created a demand for higher capacity temporary storage memory in these devices.

To meet this demand, JAE has developed the “MM80 Series” socket connector for the high-capacity DDR3 SDRAM SODIMM, which is compatible with the MO-268C JEDEC standard.

The MM80 Series is a highly reliable connector with secure positioning and stable response through use of an incomplete-insertion prevention structure that blocks the latch from locking if the memory module is not fully inserted.

_{(Note 1)DDR3: Double Data Rate 3} 

_{SDRAM: Synchronous Dynamic Random Access Memory} 

_{SODIMM: Small-Outline Dual Memory Module}

Features

• 204 pin socket for DDR3 SDRAM SODIMM, compatible with JEDEC standard (MO-268C).
• Right-angle SMT type, connector height is available in two types: 5.2mm and 9.2mm. 
• Reverse mounting type also available (heights: 5.2mm, 9.2mm).
• Structure prevents incomplete insertion by blocking the latch from locking if the memory module is not fully inserted.
• Incorrect-insertion prevention key operating voltage is DDR3 compatible 1.5V.
• Contact stability is improved with our unique contact structure.
