SMT Ultra-Miniature Coaxial Connectors - Mating Heights Owing to the Lowest Profile and the Lightest
U.FL Series
Meets up to 6 GHz Requirement
Figure 1. Mating Height Comparison
(with Hirose Electric Products)

E.FL
sFeatures
1. Mating Heights Owing to 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
world’s shortest level.
2. Extremely Small Board Occupation Area
In comparison with our E.FL Series of SMT coaxial connectors, the
receptacles offer a reduction of approximately 18% of the board
occupation area resulting in an area of just 7.7 mm2.
3. World’s Lightest
These are the world’s lightest coaxial connectors.
Receptacle: 15.7 mg
Right-angle plugs
For Ø 0.81 mm cable: 53.7 mg
For Ø 1.13 & 1.32 mm cable: 59.1 mg
4. Can Be Used Up to a Frequency of 6 GHz
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, Ø 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 Ø1.32 mm (double shield) & Ø1.13mm (single
shield) ultra-fine Teflon coaxial cable specification is also available.
7. Simple Removal of Connectors
The extraction jig permits simple removal of connectors.
8. Mating Checks Are Easy
Subminiature size notwithstanding, the lock sensation permits a
check of sure mating.

*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 100cm cable.
NOTE 2: Board type connectors were mounted to a 50glass epoxy board and
measurements were conducted with SMA conversion adapters attached.
