sFeatures
1.High Interconnection Reliability
Effective contact mating length of 1.55 mm, innovative bellow style contact design, built-in interlocking feature of mated connectors assures high electrical and mechanical reliability, providing needed rigidity to resist excessive twisting. Superior reliability of the termination of the fine coaxial cable is accomplished with batch soldering.
2. Shielded design
Metal shell encloses the connector and makes contact with all external conductors of the fine coaxial cable permitting reliable ground connection to the board side of mated assemblies.
3. Reliable mating/unmating
The connectors are self-align during mating. Optional pull-out tab permits connection and disconnection in narrow spaces. Polarized configuration prevents incorrect mating.
4. Board placement with Automatic Equipment.
The upper surface provides flat area for placement of embossed tape packaged connectors with vacuum nozzles of automatic equipment.
sApplications
Notebook computers, liquid crystal displays (LCD), video and audio devices, medical instruments, portable devices and any other device requiring reliable connection and termination with fine pitch coaxial cable. Receptacle
Flat surface for placement with Automatic Equipment

Note 1: Up to 2 cycles of reflow soldering are possible under the same conditions, provided that there is a return to normal temperature between the first and second cycle. Note 2: The temperature profile indicates the board surface temperature at the point of contacts with the connector terminals (for surface mounted plug assembly).

Handling and use precautions 0.15mm Maximum of 0.03 mm at the connector center section, with both ends of the connector as reference points. Refer to "Nylon Connector Use Handbook." 260c 5c within 5 sec, 200c min. within 25 sec. Soldering temperature: 290c 10c, Soldering time: within 2 sec. Soldering temperature: 290c 10C, soldering time: within 2 sec.
sDO NOT mate/un-mate non-terminated plugs with non-mounted receptacles.
This may lead to damage or deformation of the contacts.
sDO NOT touch the exposed contacts of the receptacle with bare fingers. This may leave non-conductive film,
cause corrosion or electrostatic discharge, affecting performance of the connectors or sensitive electronic components.
sDO NOT apply flux to the contact terminals when hand soldering the receptacle to the board. Wicking of the
flux into the electrical contact areas may lead to connection failures.
