MM40 SERIES CONNECTORS
0.5mm (.020") Contact Spacing, DIMM Socket Connectors
• • • • • • • • • • • • • •
This 8 byte Micro DIMM socket meets JEDEC standard.
Small Outline DIMM can easily be replaced with Micro DIMM
because the pin allocation is the same as the existing 144
contact SO-DIMM. Ideal for compact applications and high
density mounting.

FEATURES
• 0.5mm (.020") contact spacing and thin latch
design reduce mounting area to approximately
62%, compared to SO-DIMM socket
• Single-mold thin latch strengthened by backup
mechanism with metal springs that also
functions as hold-down
• Metal springs prevent latch from bending
inward and prevent mis-mating
• Mis-mating prevention key compatible with
3.3V and 2.5V operating voltages
• Connector height: 4mm (.157") and 5.2mm (.205")
