DiCI4a: New barium titanate based material for MLCs with Ni electrode

Abstract

A new barium titanate based X7R material has been developed for MLCs with Ni electrode. Dielectric properties of the new material are; K =3600, DF =1.6%, insulation resistance =6500ω · μF as RC product, when the dielectric layer thickness is 10μm. Performance on an accelerated life test was much superior to conventional base metal MLCs. This new material contains dysprosium oxide and cobalt oxide as main dopants to barium titanate. The performances presented in the above are attributed to this new formulation.
