7. Compliance with RoHS’ Directive
Environmentally friendly, the connectors’
comply with Europe’s RoHS’ Directive.
Cadmium, lead, mercury, hexavalent,
chromium, PBB and PBDE are not used.
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 EDS and
EMI, since both the front and back of the
card are covered with metal when
mounted. Also, since a more robust
design is possible compared to single-
sided plastic molding, the influence of
reflow heat is reduced.
Porosity treatment
PCB cut-off type
This treatment consists in coating the sur-
face with a very thin film to seal pinholes in
the gold plating. We have developed this
porosity treatment technology, which en-
sures contact reliability for thin gold plating
comparable to that of thick gold plating.

3. Constructed with double spring and
horseshoe shaped slider
• Since the entire bottom of the card
pushes the slider, the right-to-left balance
is good, which allows smooth insertion
and removal.
4. Porosity treatment achieves a high
contact reliability.
5.Thinnest socket in its class at 2.7
mm
• Improved insertion and removal reliability
• Improved resistance to corrosion
• Improved contact reliability for digital signals
APPLICATIONS
Starting with products in the IT field that
use SD memory cards such as digital
cameras, PDAs and IC recorders, you
can also use this socket in the automotive
and household appliances fields in such
products as car navigation systems and
microwave ovens.
