microSD/SIM Combo

Socket , 2.75mm Height

Molex developed its microSD/SIM combo

connector to meet the continuing

downsizing and low height requirements of

its mobile phone customers.

By combining two connectors in one, this

combo design provides significant PCB

space savings. Solder tails are located on

two sides of the connector, while still

providing good coplanarity control.

This connector was originally introduced for

3G MegaSIM phone applications, but the

different pin-out options make it suitable for

various mobile device applications.
