Product Description

SR-215-TP is a 0.215 inch semi-rigid coaxial cable engineered for microwave and RF applications, serving as a UT-215-TP compatible alternative. The cable features a silver plated copper clad steel center conductor, PTFE dielectric insulation, and a tinned copper tube outer conductor. The tinned copper outer shield provides excellent electromagnetic shielding, corrosion resistance, and easy soldering, while the rigid tube construction maintains stable impedance and low signal leakage. Compared with flexible cables, SR-215-TP is ideal for internal RF routing, microwave interconnects, and precision test fixtures. As a UT-215-TP alternative, SR-215-TP can be used in RF cable assemblies where a 0.215 inch semi-rigid cable is required, offering reliable performance for microwave instrumentation, RF modules, and antenna measurement setups.

Key Features
  • UT-215-TP Compatible Alternative - Directly usable in applications specifying UT-215-TP, offering the same 0.215 inch semi-rigid construction.
  • Tinned Copper Tube Outer Conductor - Provides strong shielding, corrosion resistance, and improved solderability during assembly.
  • Silver Plated Copper Center Conductor - Ensures low resistance, high conductivity, and consistent microwave signal transmission.
  • Stable 50 Ohm Impedance - Maintains controlled impedance for RF and microwave systems.
  • Rigid Tube Construction - Holds its shape after bending for precise routing inside RF hardware and test assemblies.
