Product Description

SR-141C is a 0.141 inch semi-rigid coax cable designed for microwave signal transmission and precision RF interconnections. This RF transmission line uses a silver plated copper center conductor, PTFE dielectric insulation, and a seamless copper tube outer conductor. Unlike cables that use silver plated copper clad steel conductors, the copper conductor used in SR-141C provides non-magnetic performance and higher electrical conductivity, which is especially important in sensitive RF measurement environments. The rigid copper outer conductor structure provides excellent shielding effectiveness and stable impedance control, helping maintain signal integrity in high frequency systems. Because the cable can be formed into a fixed shape, it is widely used for microwave interconnects inside RF modules, test equipment, and laboratory measurement systems. SR-141C follows the widely used 0.141 inch semi-rigid cable format, making it suitable as a compatible alternative to UT-141C for many RF cable assemblies and microwave hardware designs.

Key Features
  • Non-Magnetic Center Conductor - The silver plated copper conductor ensures non-magnetic performance, making the cable suitable for sensitive RF measurement systems and instrumentation.
  • High Electrical Conductivity - Compared with copper clad steel conductors, pure copper provides improved conductivity and lower signal resistance.
  • Rigid Copper Tube Shield - The seamless copper outer conductor offers excellent electromagnetic shielding and reduces signal leakage.
  • Stable 50 Ohm RF Transmission - Designed for controlled impedance systems used in microwave communication and RF testing.
  • 0.141 Inch Industry Standard Size - Compatible with many semi-rigid connector types and microwave cable assembly designs.

FAQ
Q: What is SR-141C semi-rigid coax?
A: SR-141C is a 0.141 inch semi rigid coaxial cable designed for RF and microwave signal transmission. The cable uses a silver plated copper center conductor, PTFE dielectric insulation, and a seamless copper tube outer conductor to provide stable impedance and strong shielding performance. We also offer silver plated copper or tinned copper outer conductor variants.
Q: Is SR-141C compatible with UT-141C cable?
A: Yes. SR-141C follows the same 0.141 inch semi-rigid coaxial cable standard and can be used as a compatible alternative to UT-141C in many RF cable assemblies and microwave interconnect applications.
Q: What is the difference between SR-141 and SR-141C cable?
A: The main difference is the center conductor material. SR-141 typically uses a silver plated copper clad steel conductor, while SR-141C uses a silver plated copper conductor. The copper conductor in SR-141C provides non-magnetic performance and higher electrical conductivity, which is preferred in certain RF measurement and instrumentation systems.
Q: Why use a non-magnetic RF transmission line?
A: Non-magnetic cables are important in sensitive RF and microwave measurement environments. Magnetic materials can potentially influence measurement accuracy, so cables with copper conductors such as SR-141C are often selected for precision instrumentation.
Q: What impedance does SR-141C cable have?
A: SR-141C is designed with a characteristic impedance of 50 ohms, which is the standard impedance used in most RF, microwave, and communication systems. 25 ohms variant and custom impedance is also available.
Q: Can SR-141C be used to build RF cable assemblies?
A: Yes. SR 141C is commonly used to manufacture microwave jumper cables, coax pigtail, RF test cables, and custom semi-rigid cable assemblies with precision RF connectors.
Q: What applications typically use 0.141 inch semi-rigid coax cable?
A: 0.141 inch cables are widely used in RF test equipment, microwave instrumentation, antenna measurement systems, aerospace electronics, and laboratory development environments.
Q: Can SR-141C be soldered directly to a PCB?
A: Yes. Semi-rigid cables can be soldered directly to RF circuit boards and microwave modules, making them suitable for controlled RF signal launches and test fixtures.
Q: Do you provide custom cable assemblies based on SR-141C?
A: Yes. Custom cable assemblies including cut to length cables, connector installation, and RF test cable configurations can be manufactured according to project requirements.
Q: What information is typically required for purchasing SR-141C cable assemblies?
A: Procurement teams usually provide details such as cable length, connector types, operating frequency range, and quantity requirements to ensure the correct cable assembly is produced.
