Overview

PTFE (polytetrafluoroethylene, Teflon) jacket per MIL-W-16878. Lowest dielectric constant of the practical wire insulators (2.1 vs PVC’s 3.5), highest temperature rating (260°C). Adds cost but reduces dielectric absorption.

Typical uses

  • studio microphone cables
  • tonearm wire
  • high-end interconnects
