Ultra-Small Surface Mount Coaxial Connectors - 1.18mm Mated Height
W.FL2 Series
2008.2
■Features
1. Nominal mated height of 1.18 mm (Max. 1.3
mm)
2. Small board footprint
As with W. FL Series, the receptacles occupies an area
of 3.4 mm_ and share the same land pattern.
Note: The W. FL2 Series and the W. FL Series are not
compatible.
3. Extremely light weight
Receptacle weight of 5.0 mg and plug weight of 17.4 mg
makes the connectors one of the lowest weights on the
market
4. Accepts high frequency transmission of DC
to 6 GHz
DC to 3 GHz: V.S.W.R. of 1.3 max.
3 GHz to 6 GHz: V.S.W.R. of 1.4 max.
5. Automatic board placement
Packaged on tape-and-reel the receptacles can be
placed with vacuum nozzles of the automatic placement
equipment.
6. Plugs are terminated with ultra-fine coaxial
(fluorinated resin insulated) cable
Standard ultra- fine coaxial cable of 0.81 mm diameter
(single braid shielding) is used for the plug termination,
assuring secure and stable connections.
7. Simple connector mating / un-mating
Use of the available mating / un-mating tools assures
correct connection / disconnection of the plug and
receptacle.
■Applications
Mobile phones, wireless LAN related applications, Bluetooth
protocol devices, PDA, GPS, wireless communication
devices, electronic measuring instruments and any
application requiring high frequency transmission using
ultra-small coaxial connectors.

■Precautions
1. Plugs
●Use of the extraction tool is absolutely
mandatory. Any attempt of unmating by
pulling on the cable may result in damage
and affect the mechanical / electrical
performance.

(1) Recommended reflow
temperature profile
qThe temperature of the printed circuit board surface
temperature at the points of contact with the terminals.
wReflow soldering should be performed at a printed
circuit surface temperature of 250°C max.
eIn individual applications the actual temperature may
vary, depending on the solder paste type, volume /
thickness and board size / thickness. Consuly your
solder paste and equipment manufacturer for specific
recommendations.

(3) Precautions
qAlign the mating tool W.FL-LP-IN or the
mating end of the tool W.FL2-LP-IN.OUT over
the plug end of the cable assembly.
wFirmly place the tool over the plug until it is
secured in the tool.
ePlace the plug cable assembly (held in the
tool) over the corresponding receptacle.
rAssuring that the plug and receptacle are
aligned press-down perpendicular to the
mounting surface until both connectors are
fully mated.
tRemove the mating tool by carefully pulling it
up.Removal of the tool
qTo disconnect connectors, insert the extraction side of insertion and extraction jig W.FL2-LP-IN.OUT and perform as
described in the diagram below.
Do not twist connectors excessively during mating / unmating.

The connectors are NOT designed to operate in the following environments:
•Exposed to a excessive amounts of fine particles and dust
•Regions and places having a high density of sulfur dioxide, hydrogen sulfide, nitrogen dioxide or other corrosive gasses.
•Environments having large rapid variations in temperature.
(2) Storage conditions -
Receptacle
Store in the Hirose Electric packaging.
Temperature: -10 to +40ç, Humidity: 85% max.
