Features
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 mm
2
.
3. World's Lightest
These are the world's lightest coaxial connectors.
Receptacle: 15.7 mg
Right-angle plugs
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
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.
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 50
glass epoxy board and
measurements were conducted with SMA conversion adapters attached.

Inspection Receptacle
This receptacle is used for inspecting the continuity,
withstand voltage, and other aspects of the harness
product.
NOTE: The U.FL side coupling portion has a weaker lock than
the regular product and, therefore, cannot be used for
purposes other than performance measurements.

Usage Precautions
1. Plugs
(1) Connection/
disconnection of
connectors
(2) Permissible load on
the cable after
connector coupling.
(3) Precautions
1) To disconnect connectors, hook the end portion of E.FL-LP-N and U.FL-LP-N-2 onto the connector cover and pull off
vertically in the direction of the connector coupling axis.
1)
To remove the connector directly, hold the connector cover and pull off
vertically in the direction of the connector coupling axis. (Please exercise
caution so as not to injure fingertips or nails.)
2) To couple the connectors, the coupling axes of both connectors are
aligned and the connectors are inserted as perpendicularly as possible.
Do not attempt to insert on an extreme angle.
After the connectors are coupled, do not apply a load to the cable in excess of the values indicated in the diagram
below.
Please note that excessive twisting in the action of insertion or removal will cause damage.
(1) Recommended
temperature profile
(Reference)
Recommended Temperature Profile (Reference)
1) The temperature indicates the printed circuit board surface temperature of the connector lead portion.
2) The reflow soldering method should be performed at a peak temperature of 240C or less at the surface of the
printed circuit board.
3) The temperature profile will change depending on conditions which include such factors as the size of the board,
the solder used, and the solder thickness.
(3) Recommended screen
thickness

(2) Recommended hand
soldering conditions
