MICRO-SD CARDS GET CONNECTED:
A PRESION ULTRAMINIATUR DEVELOPMENT FROM YAMAICHI ELECTRONICS
YAMAICHI ELECTRONICS has introduced the PJS008-2000 card connector for microSD memory cards. It features a small form factor and a mounted height profile of only 1.85 mm. As a so-called reversed type, this connector is mounted on the underside of the PCB.
The push/push mechanism allows the card to travel a mere 3.0mm to 4.35 mm from the locked to the unlocked (ejected) position, while the card brake feature ensures that the card does not fall out completely. In addition, the strengthened contact pressure at the power and ground contact surfaces effectively prevents electrical interruption. Of course, the PJS008 series is RoHS compliant, and it is shipped in tape-on-reel packaging for automated SMT assembly.

Background information on microSD™
Originally developed by SanDisk in cooperation with Motorola, and since adopted by the SD Card Association, the new microSD card (formerly TransFlashTM) is fully compatible with TransFlash, having exactly the same dimensions and number of contacts (both card types measure 11 mm x 15 mm x 1 mm). Integrated safety functions enable the storage of saved content in the same manner as SD cards.
The main applications are in mobile telephones and portable music players. The format is currently supported by, and used in, products of mobile phone manufacturers - primarily Kyocera, Motorola, Samsung, LG Electronics and Sagem Communication. SanDisk has announced plans for "transitioning" its TransFlash line of products to the microSD standard. The storage capacity ranges from 128 MB to 512 MB. Similar to miniSD cards, microSD cards can be used in SD slots via connection with an adapter.
I would be pleased to assist you further!
