1.37 mm Cable Assembly, U.FL to SMA Female Bulkhead, 140 mm
Locally Stocked

1.37 mm Mini-Coax cable assemblies are used inside electronics to interface a surface mount RF connector located on a PCB to an externally mounted connector typically mounted on the side of the device.

This cable assembly is used to provide an external SMA Female connector from a device with a U.FL connector mounted on its PCB. Typically this is to allow the connection of an external antenna or attachment of an antenna feeder cable that uses an SMA Male connector.

The U.FL interface uses an IPEX MHF series connector, suitable for any Hirose U.FL, LTI IPX, Amphenol AMC, or Tyco UMCC interface.

Recommended Use

These cable assemblies are stocked locally and supplied individually packaged for use in electronics prototyping, as replacements, or critical spares.

Bulk supply can be arranged at significantly reduced pricing, with global shipment via our facility in Guangzhou, China.
