RT/duroid® 5280LZ High Frequency Laminates

RT/duroid® 5280LZ high frequency laminates are filled PTFE composites reinforced with woven fiberglass.

RT/duroid 5280LZ filled PTFE composites, reinforced with woven fiberglass, are engineered for precise stripline and microstrip circuit applications that demand dimensional stability throughout PWB processing.

Features

  • Dk of 2.06 or 2.10 depending on glass
  • Dissipation factor of 0.0028 at 10GHz
  • Woven glass reinforced construction

Benefits

  • Lowest dielectric constant available
  • Low X, Y, & Z axis CTE
  • Glass-reinforced construction delivers industry-leading Z-axis CTE from -50C to 288C
  • Lightweight/low density
  • Uniform electrical properties over wide frequency range
