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.

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. Figure 3. U.FL-LP-066and U.FL-R-SMT
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.
sApplications
Mobile phones, wireless communications equipment, electronic measuring instruments, GPS, wireless LAN, Bluetooth etc. 2002.3
