0.6mm Pitch Board-to-Fine-Coaxial Cable Connectors
DF21 Series
■Features
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.
■Applications
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

BUsage Recommendations
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).

precautions
■
DO NOT mate/un-mate non-terminated plugs with non-mounted receptacles.
This may lead to damage or deformation of the contacts.
■DO 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.
■DO 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.
Soldering temperature: 340ç ±10°C, soldering time: within 5 sec.
0.15mm
Maximum of 0.03 mm at the connector center section, with both ends of the connector as reference points.
