Completed Research Projects

"There are a number of research themes and projects within the CDS that are having an impact on our work here at Murata. These include the modeling and characterization approaches that are being used to address reliability in base metal capacitors. We are also impressed by materials that can fire less than 600˚C; for example, the Penn State work on the barium tellurate oxides that could be cofired with alumina. We are also interested in the high power capacitors that have potential for future hybrid electric cars.   Yukio Sakabe Murata Mfg. Co., Ltd.
