DDR3 Standard Memory Module Compatible
High-Speed Transmission Connector
"MM80 Series"Has Been Developed
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
z204 pin socket for DDR3 SDRAM SODIMM, compatible with JEDEC standard (MO-268C).
zRight-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).
zStructure prevents incomplete insertion by blocking the latch from locking if the memory module is not
fully inserted.
zIncorrect-insertion prevention key operating voltage is DDR3 compatible 1.5V.
zContact stability is improved with our unique contact structure.
