Description
50 Ohm Flexible Coaxial Cable | FEP Jacket | PTFE Dielectric
The ROSNOL RG-142B/U is a high-performance 50-ohm coaxial cable designed for RF applications up to 8 GHz. It features a silver-plated steel/copper inner conductor (0.94 mm [0.037 inch]), PTFE dielectric (2.95 mm [0.116 inch]), and dual silver-plated copper shields (3.59 mm [0.141 inch] and 4.22 mm [0.166 inch]). Capacitance is 97 pF/m with 70% velocity of propagation and screening effectiveness ≥ 85 dB. Attenuation ranges from 0.04 dB/ft [0.13 dB/m] at 0.1 GHz to 0.44 dB/ft [1.43 dB/m] at 8 GHz.The cable is jacketed with FEP (4.95 mm [0.195 inch]), supports static and dynamic bend radii of 30 mm [1.181 inch] and 50 mm [1.969 inch], respectively, and operates up to 2.5 kVrms. It is RoHS compliant and suitable for extreme temperatures from -65°C to +165°C.
