Material Notes:

CuClad 233 uses a medium fiberglass/PTFE ratio to balance lower dielectric constant and improved dissipation factor without sacrificing mechanical properties.Cross Plied Woven Fiberglass, alternating plies are oriented 90° to each otherHigh PTFE to Glass RatioBetter dielectric constant uniformity than comparable non-woven fiberglass reinforced laminatesBenefits:Electrical and Mechanical isotropy in the X-Y PlaneExtremely Low LossWell Suited for Er Sensitive CircuitsTypical Applications:Military Electronics (Radars, ECM, ESM)Microwave Components (Filters, Couplers, LNAs, etc.)Information provided by Arlon Materials for Electronics (MED).
