DIELECTRIC MATERIALS - Magnetics Group
TRAK Ceramics, Inc. n18450 Showalter Road, Box 112 n Hagerstown, Maryland 21742 nFax Ceramics, Inc. produces a wide range of lowloss dielectrics commonly used in conjunction with ferritecirculators, isolators, and phase shifters. Some areavailable as substrates for thin and thick film circuitsor for high Q capacitor applications. Dielectricconstants ( ') span from to well above 100. Ceramicswith low DIELECTRIC constants from to 10 often arerequired as supports for our advanced expansion and thermal conductivity for any given DIELECTRIC material cannot be variedsignificantly without altering the favorable electricalproperties. The vast majority of all structural ande l e c t ronic ceramics conduct heat very poorly. However,alumina (Al2O3, '= ) is a modest , it s temperature coefficient of 'which isapproximately +115 ppm/ C can be adjusted to near0 ppm/ C. Magnesia (MgO, '=10) exhibits outstandingthermal conductivity combined with very high thermalexpansion which matches more closely with that ofmetals.
