Our inventory of Belden Special Audio Cables includes their Mini Coax Cable. Its construction consists of a 28 AWG solid tinned copper conductor, polypropylene insulation, a black PVC jacket, and a bare copper braid shield. Our mini-coax has a temperature rating of 105°C and an NEC Type CMH cable rating. It also passes the VW-1 flame test.
Belden's Low noise cable is also offered in our inventory of Specialty Coaxial Cable. All are high-quality cables meant to reduce triboelectric noise. Triboelectric noise is internal noise that happens when a cable flexes or vibrates. This movement creates friction among the cable’s components (insulation, conductor, etc.) which then produces an electric charge that can then disrupt signal transmission. These low noise cables reduce the disruptive signals, also known as noise, for cleaner signal transmission overall.
RG174U, RG59U, and RG58U options are in our stock of Belden low noise cable. They are built with bare copper-covered steel or tinned copper conductors, polyethylene insulation, and a black PVC jacket. However, the shielding in these cables differs in accordance with each RG number. The RG174U cable features a tinned copper braid, while the RG58U cable has a combination Duobond II and tinned copper braid shield. The RG59U cable has a bare copper braid shield. We do not recommend these cables for radio frequency use.
