1. Mating Heights Owing to Worlds Lowest Profile
Height from the printed circuit board when mates a receptacle with
a (right-angle) plug is 2.5 mm maximum. This low Profile is at the
worlds shortest level.
2. Extremely Small Board Occupation Area
U.FL-R-SMT U.FL-LP-040
In comparison with our E.FL Series of SMT coaxial connectors, the
receptacles offer a reduction of approximately 18% of the board
2
occupation area resulting in an area of just 7.7 mm .
3. Worlds Lightest
These are the worlds lightest coaxial connectors.
Receptacle: 15.7 mg
Right-angle plugs + Female center contacts
For 0.81 mm cable: 53.7 mg
For 1.13 & 1.32 mm cable: 59.1 mg
4. Can Be Used Up to a Frequency of 6 GHz
Figure 3. U.FL-LP-066and U.FL-R-SMT
To meet the frequency requirements of a wide variety of miniature
equipment, these connectors offer high frequency performance
from DC to 6 GHz.
5. Can Be Used with Automatic Mounting
The embossed tape packaging specification of the receptacles
permits automatic mounting.

6. Use of Ultra-Fine Teflon Cable
From among the types of suitable cable, 0.8 mm (single shield)
outside diameter ultra-fine Teflon coaxial cable has been made a
standard specification in consideration of improving the
construction qualities and construction area.
An external diameter 1.32 mm (double shield) & 1.13mm (single
shield) ultra-fine Teflon coaxial cable specification is also available.
7. Simple Removal of Connectors
The extraction jig permits simple removal of connectors.
Applications
8. Mating Checks Are Easy
Mobile phones, wireless communications
Subminiature size notwithstanding, the lock sensation permits a
equipment, electronic measuring instruments,
check of sure mating.
GPS, wireless LAN, Bluetooth etc.

*V.S.W.R. Measurement System
The above V.S.W.R. standard values were measured using the measurement system of the diagram below.
NOTE 1: Cable type connectors were measured with SMA conversion adapters
attached to both ends of the harness product of a suitable 100-cm cable.
NOTE 2: Board type connectors were mounted to a 50 glass epoxy board and
measurements were conducted with SMA conversion adapters attached.
