Latest Patents

Hiroyasu Konakaka holds a patent for a dielectric ceramic, a method for making the same, and a monolithic ceramic capacitor. The dielectric ceramic is composed of ABO as the main component and incorporates a rare earth element. In this composition, A represents barium, which may be partially replaced with calcium and strontium, while B represents titanium, which may be partially replaced with zirconium and hafnium. The patent details that at least 70% of the crystal grains of the dielectric ceramic have a cross-section where a first region containing dissolved rare earth elements occupies 5 to 70% of the area, and a second region free of the dissolved rare earth element occupies 10 to 80% of the periphery. This innovative dielectric ceramic exhibits superior capacitance-temperature characteristics and high reliability when used in monolithic ceramic capacitors.
