MAGTREX 555 materials are constructed from a proprietary, low loss, high resistivity ceramic filler and a high temperature thermoplastic matrix. This yields a system which is conformable, through hole via capable, and mechanically and electrically stable. These laminates feature a closely matched X/Y axis permeability and permittivity of 6 and 6.5, respectively, along with low magnetic and dielectric loss below 500 MHz. MAGTREX 555 high impedance laminates feature a low X, Y, Z CTE closely matched to copper for thermal reliability and are available in thicknesses from 40 to 260 mils. They are offered with or without copper cladding.
