RT/duroid 5870 laminates offer high frequency with low dielectric constant (Dk). The randomly oriented microfibers in the PTFE composites result in exceptional Dk uniformity. With its low Dk loss, RT/duroid 5870 laminates are well suited for high frequency/broadband applications where dispersion and losses need to be minimized.

Features

  • Dk of 2.33 +/- .02
  • Dissipation factor of .0012 at 10GHz
  • Low moisture absorption
  • Isotropic

Benefits

  • Lowest electrical loss for reinforced PTFE material
  • Easily cut, shared and machined to shape
  • Resistant to solvents and reagents used in etching or plating edges and holes
  • Ideal for high moisture environments
  • Well-established material
  • Uniform electrical properties over wide frequency range
