Socket connector for DDR3 SDRAM SODIMM

Outline
 The MM80 series is a socket connector for the high-capacity DDR3 SDRAM SODIMM (Note 1), which is compatible with the MO-268C JEDEC standard.
 Right-angle SMT type connector
 Contact stability is improved with our unique contact structure. Structure prevents incomplete insertion by blocking 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).
-  Incorrect-insertion prevention key operating voltage is DDR3 compatible 1.5V.
-  Right-angle SMT type, connector height: 5.2mm.
-  Reverse mounting type also available (heights: 5.2mm).

Applications
 Notebook PC, Desktop PC, Server, FAX, Copier, etc.
