0.3 mm Pitch, Vertical mating, Board-to-Fine Coaxial Cable Connectors
DF56 Series
2010.9
■Features
1.Small mated height and board occupied space
Small pitch (0.3mm) and mated height (1.25mm) allows use
in space-restricted areas.
It’s a small connector with mated height of 1.25mm (1.35mm
MAX) and depth of 2.6mm.
2.Compatibility with minor diameter hinges
AWG44 x 40 are compatible with hinge diameters of Ø2.8mm,
and minor diameter hinges can be passed through internal
equipment.
3.Reliable electrical and mechanical connection
Despite its small mated height, unique contact configuration
assures highly reliable connection, with effective mating length
of 0.21mm.(fig.1)
4. Durable plug construction
Formed metal shells on the top and side surfaces form a
strong and rigid assembly.
5.Enhanced shielding and ground connections
Metal shells on the plug and receptacle connect to each other
with a reliable multi-point ground contacts, assuring reliable
ground connection and EMC protection. (fig 2.)
6.Reliable lock
Fully mated condition is assured with reliable locks at
4 locations, confirming it with a distinct tactile click. (fig 3.)
7. Solder wicking prevention
Nickel barriers prevent solder wicking in the critical contact
areas.

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.
2. Recommended manual
soldering
Manual soldering: 350ç for 3 seconds
Do NOT use flux compound when manual soldering.
3. Recommended screen
thickness and open area ratio
(Pattern area ratio)
Standard thickness 0.1mm
Open area ratios : Lead terminal 60%
: Ground terminal 100%
4.Board warpage Maximum of 0.02 mm at the connector center, with both ends of the connector as
reference points.

■Precautions
Precautions
■Mating
Mate the plug with receptacle by pressing straight against the entire plug surface.
Do NOT mate the plug while holding by the teminated cable.
■Un-mating
Use a dedicated extraction tool to un-mate the plug.
Insert the tool under either end of the plug and pull straight up as illustrated.
■Do not mate / un-mate the connectors when receptacle is not mounted on the board.
■ In the manual soldering process, don't carry out the flux coating which will cause a flux blister on
the connector.
■Excessive scoop insertion or extraction may result in damage.
