Multiphase dielectric composition and multilayered device incorporating the same

The present invention relates to dielectric compositions for electronic applications, and more particularly to a low loss, substantially lead free dielectric composition that is co-fireable with a ceramic material for forming multilayer ceramic devices. A multiphase dielectric composition for a multilayered ceramic device (), and devices incorporating the same, including a (SrCa)TiOdielectric powder and a glass that is substantially free of lead having a weight ratio of about 35 to about 65 parts powder: about 65 to about 35 parts glass, and having a particle size of about 1 to about 2.5 micron (um) and having a dielectric constant (K) of about 18 to about 30 and an electrical Q of at least about 300 to about 550.
