RG178B/U Bulk Coaxial Cable (by the foot)
Ultra-Miniature High-Temperature RF Coaxial Cable
This ultra-miniature 50-Ohm RG178B/U coaxial cable offers high-temperature performance (-55°C to +200°C) in a sub-1.80 mm profile. Housed in a brown FEP jacket, it features a stranded silver-plated copper-clad steel conductor, solid PTFE dielectric, and a dense silver-plated copper braid shield. With a tight 0.4-inch bend radius and support up to 3 GHz, it is optimized for space-constrained wireless modules, aerospace avionics, and medical instrumentation.
