What is the Smallest Diameter Micro Coaxial Cable Available

Micro coaxial cables are designed with a much smaller outer diameter compared to traditional coaxial cables, typically measuring 1 mm or less. This compact size allows them to fit into tight spaces and makes them highly flexible.

Ultra – Fine Options

48 AWG Cables: One of the thinnest in the coaxial cable category is the 48 AWG ultra – fine coaxial cable. It has a diameter of approximately 0.17 mm. These cables are used in high – precision applications where space is severely constrained, such as in some miniature medical devices and ultra – small electronics. Manufacturing such a cable requires exceptional precision, high – quality materials, and strict process control.
AWG 50 Wires: The outer diameter of an AWG 50 stranded wire is reduced to only 0.15 mm. These micro coaxial wires are used in applications where extremely small size and lightweight are crucial, often in aerospace or military – grade micro – electronics.

Standard Micro – Coax Diameter Ranges

Micro – coax cables generally have outer diameters ranging from 0.22 to 1.16 mm. Their center conductors, described using the American Wire Gauge (AWG) standard, range from 30 to 46 AWG. For example, a 30 AWG center conductor has a diameter of 0.30 mm, while a 46 AWG center conductor has a diameter of 0.048 mm.

Considerations for Using Ultra – Small Cables

Signal Loss: Smaller diameter cables, especially those with very thin center conductors like the 48 AWG or AWG 50, are more prone to signal loss. This is because the resistance of the conductor increases as the diameter decreases. So, they are best suited for short – distance applications where the signal doesn’t have to travel far.
Connectors: These micro coaxial cables typically do not use standard coaxial connectors. Instead, they use specialized micro coax connectors such as u.fl connectors (developed by Hirose Electric Group), MHF connectors (by I – Pex), or AMC connectors (by Amphenol). These connectors are designed to match the small size of the cables and ensure proper electrical connection.
