Patent number: 10759705Abstract: A dielectric composition has barium, strontium, and bismuth calcium titanates constituting a main component and subcomponent. “a” mol % represents a content of barium titanate in terms of BaTiO3, “b” mol % strontium titanate in terms of SrTiO3, and “c” mol % bismuth calcium titanate in terms of CaBi4Ti4O15 in the main component composition. a+b+c=100 is satisfied, 50?a?83, 12?b?49.5, 0.5?c?5. The dielectric composition includes a first subcomponent constituted by at least one compound including one of manganese, iron, and chromium. The first subcomponent is included in a ratio of 0.2 wt % or more and 3 wt % or less in terms of total of MnCO3, Fe2O3, and Cr2O3 with respect to 100 wt % of the main component. The dielectric composition includes a second subcomponent compound including niobium, included in a ratio of 0.1 wt % or more and 3 wt % or less in terms of Nb2O5 with respect to 100 wt % of the main component.Type: GrantFiled: March 19, 2019Date of Patent: September 1, 2020Assignee: TDK CORPORATIONInventors: Liu Hailong, Liang Liping, Daisuke Ohtsu

Patent number: 10710932Abstract: The object of the present invention is to provide the dielectric composition having good specific permittivity, high DC breakdown voltage and AC breakdown voltage, small dielectric loss and heat generating property, and good temperature property even though lead is not substantially used. A dielectric composition of the first aspect includes a, Ca, Bi, Ti, and Sr, wherein the dielectric composition includes two phases having different Sr characteristic X ray intensities when a characteristic X ray intensity derived from Sr is measured by EPMA, and when Sr1 represents the characteristic X ray intensity derived from Sr of a first phase measured by EPMA and Sr2 represents the characteristic X ray intensity derived from Sr of a second phase measured by EPMA, a ratio (Sr2/Sr1) of Sr2 with respect to Sr1 satisfies 2 or larger.Type: GrantFiled: March 19, 2019Date of Patent: July 14, 2020Assignee: TDK CORPORATIONInventors: Daisuke Ohtsu, Taku Masai, Liu Hailong, Liang Liping
