IEC 61196-8:2012 PDF

IEC 61196-8:2012 Overview

IEC 61196-8:2012 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for semi-flexible coaxial communication cables with a polytetrafluoroethylene (PTFE) dielectric. It forms part 8 of the IEC 61196 series dedicated to coaxial communication cables. This standard focuses on cables utilizing a tin-soaked copper wire braid as the outer conductor, designed primarily for high-frequency applications ranging from 500 MHz up to 18 GHz. These cables serve critical roles in microwave and wireless equipment as well as other signal transmission systems.

IEC 61196-8:2012 should be used alongside IEC 61196-1 for a comprehensive understanding of generic specifications, definitions, and basic requirements related to coaxial cables.

Key Topics Covered

The standard details the construction, materials, testing, and performance characteristics for semi-flexible coaxial cables with PTFE dielectric, including:

• Cable Construction & Materials
  • Inner conductor specifications: solid silver-plated copper wire or silver-plated copper-clad steel wire with minimum silver coating thickness of 1 µm.
  • Dielectric design: polytetrafluoroethylene (PTFE) ensuring optimal electrical insulation and stability at microwave frequencies.
  • Outer conductor: tin-soaked copper wire braid providing effective shielding against electromagnetic interference.
• Electrical Characteristics
  • Frequency range: 500 MHz to 18 GHz, suitable for microwave and wireless communication.
  • Characteristic impedance details ensuring signal integrity and compatibility with RF systems.
