AD350A PTFE, woven fiberglass, ceramic filled specialty material has been developed to provide high thermal conductivity and low CTE for use in higher power designs. Where temperature extremes are normal and heat rejection is a primary consideration, AD350A continues to perform.

Features

  • Well controlled dielectric constant of 3.50 +/- .05
  • Low insertion loss tangent of .003 at 10 GHz
  • Low Z-axis thermal expansion of 35 ppm/°C
  • Larger Panel Sizes Available

Benefits

  • Superior plated through-hole (PTH) adhesion
  • Excellent heat dissipation and management
  • High consistency performance
