FEATURES

Ne
1.The double-sided metal shell and
laser welding provides superior
robustness and EMI resistance.
When a card is inserted, both sides of the
card are covered with the metal shield,
which offers superior EMI resistance.
The shell also allows for more robust
design than that with the single-sided
resin-molded shell, reducing effects of
the reflow heat.
2.The twin contact power terminals
offer superior contact reliability.
Compared to single contact terminals,
the twin contact structure used in the
power terminals reduces the possibility of
sudden power cut-down.
What’s a microSD™ card?
The microSD™ card is an ultra-miniature
memory card that is completely compatible
with the TransFlash card, which is increas-
ingly adopted mainly by mobile phones.
The microSD™ card is a new-generation
memory card certified by the SD Card
Association, which is an organization for
standardizing SD cards, in July 2005 as a
successor to the TransFlash card.

3.The PCB cut-off reverse type has
achieved the ultra-low height from the
board surface of 0.83 mm.
Contributes to the reduction of the
target equipment’s thickness.
* Possible only with the PCB cut-off reverse type.
APPLICATIONS

Mobile phones and compact portable
On board mounting
reverse type
The PCB cut-off reverse type is the type
in which the socket fits into an area cut
out from the PC board. Including the PC
board, the reduced overall thickness
allows for the lowest possible profile.

4.The detection accuracy shall not be
affected by the card thickness.
The detection switch detects a card in the
card insertion direction.
Highly reliable detection is possible
regardless of variations in card
dimension, material, and manufacturing
method. (NC contact)
5. Jump-out protection mechanisms
6. Fully compatible with T-Flash card
