Effects of Additives on Dielectric Properties and Microstructure of MLCC X7R Composition
Effects of additives on electrical properties and microstructure of MLCC X7R dielectrics have been investigated. The additives of glass frit or oxide form were added in the same main composition by the different powder processing conditions. As a result of the dielectric property and microstructure analysis, the composition having the glass layer with dopant concentration gradient showed the excellent dielectric properties. The MLCCs were fabricated with the excellent composition and all dielectric properties satisfied the X7R requirements.
Key words: X7R, MLCC, Glass frit, Dielectric characteristic, Core shell
