TRIPLE CONTACT CONSTRUCTION OF
FEATURES
1. Triple contact construction for
improved prevention of minute circuit
cutoff from dropping.
The terminals in the power supply section
have been made with triple contacts. This
construction means that there will be no
circuit cutoff over 0.1 µs even if the
device is dropped.
2. Robustness and resistance to ESD
and EMI have been fortified using
upper and lower metal shells.
The socket is effective against ESD and
EMI, since both the front and back of the
card are covered with metal when
inserted.
Also, since a more robust design is
possible compared to single-sided plastic
molding, the influence of reflow heat is
reduced.
3. Constructed with double spring and
horseshoe shaped slider
Since a horseshoe shaped slider and
double spring system is used and since
the entire bottom of the card pushes the
slider, the right-to-left balance is good,
which allows smooth insertion and
removal.
4. Better contact reliability through
use of V notch construction in
detection contact.
V notch construction, a design proven in
our narrow-pitch connectors, is used in
the detection contact. This increases
resistance to the environment and to
dust.
5. 2.3 mm ultra-thin socket thickness
contributes to device compactness
Space savings realized. Width: 24.3 mm
(incl. solder terminal) × Depth: 21.5 mm
(incl. lead terminal) × Thickness: 2.3 mm
6. Simple card lock mechanism
(prevents card from falling out)

APPLICATIONS
Use in applications (mobile phones and
voice recorders, etc.) that employ a
miniSD™ card.

What is a miniSD™ card?
To satisfy the trend toward applications that
are getting thinner and more compact, the
miniSD card, at 40% the volume, is an even
more compact version of the SD memory
card that is now enjoying a solid reputation
in the market.
● What is V notch construction?
By having the contacting portion of the
detection contact make contact with the
edges and by increasing the per-unit-area
contact pressure, this product is more
effective at the removal of foreign matter.
This also helps to prevent foreign matter
from getting inside.
