What does RG316/U mean?

RG316/U Coaxial Cable: Small Diameter, Large Fire Resistance

RG316/U designates a special form of coaxial cable.  This coax cable has a 50 Ohm impedance (figure 1), making it ideal for data transmission.  RG316/U has a small diameter (0.098" nominal), is extremely flexible due to its stranded center conductor (helpful video tip), and has an FEP outer jacket that lends it an operating temperature of up to 200°C.

Common applications for RG316/U include linking test or data machines being used in a hot environment, LAN/WAN or GPS where high temperature performance is needed, labs where potentially flammable chemicals are used, and construction situations where fire codes require FEP rated cable.

RG316/U is easy to work with given its flexibility. For that reason, L-com sells RG316/U bulk cable in three put-ups: 100 foot coax coil, 500 foot coax spool, and 1000 foot coax spool.  L-com also carries plenty of coaxial connectors specifically shaped for thinner cables like RG316/U. 

Pre-terminated RG316/U cables are also available, made with SMA, SMB, SMC, and MCX connectors.
