Description
RG-178 LSZH Flexible Coaxial Cable | 50 Ω | Single Shielded | DC–6 GHz
The ROSNOL RG-178 LSZH flexible coaxial cable is a 50 Ω RF transmission cable engineered for stable signal performance from DC up to 6 GHz. It features a compact overall diameter of 1.90 mm (0.075 in), making it suitable for high-density routing and space-constrained assemblies. Electrical characteristics include capacitance of 98 pF/m, velocity of propagation at 70%, and signal delay of 4.7 ns/m, ensuring consistent signal integrity across RF and microwave systems. Shielding effectiveness reaches ≥60 dB up to 1 GHz, supporting reliable EMI protection. Typical attenuation values range from 0.58 dB/m at 0.1 GHz to 4.13 dB/m at 6 GHz, with maximum power handling up to 225 W at lower frequencies. The cable supports an operating voltage of ≤0.5 kVrms and withstand voltage of 1.5 kV (1 minute). Mechanical performance includes a minimum bending radius of 10 mm (static) and 27 mm (dynamic), supporting flexible installation requirements.
The cable construction incorporates a silver-plated copper-clad steel inner conductor (7/0.102 mm), offering improved tensile strength compared to pure copper while maintaining good conductivity; however, it may exhibit slightly higher resistance than solid copper in ultra-low-loss applications. The PTFE dielectric (0.86 mm) provides excellent thermal stability and low dielectric loss, though it increases material cost. A silver-plated copper braided outer shield (1.30 mm) ensures effective shielding and corrosion resistance, while the LSZH (Low Smoke Zero Halogen) jacket enhances fire safety by minimizing toxic emissions, though it may be less flexible than PVC alternatives. This combination balances durability, RF performance, and safety compliance for demanding environments.
ROSNOL’s cable solutions are precision-engineered to meet the rigorous demands of RF and microwave transmission systems. Manufactured under ISO 9001-certified processes, ROSNOL cables deliver consistent high quality and performance at competitive pricing, making them a reliable alternative to products from leading European and American brands. All ROSNOL cables are fully compliant with global environmental and safety regulations, including RoHS and REACH. Customization services for materials, shielding, and mechanical design are available to support specialized application requirements.
