  • Publication number: 20100124663
    Abstract: A resin composition with no substantial halogen element content contains a tungsten powder, a polyester elastomer, silica, a polysiloxane compound, and melamine cyanurate. Relative to 100% in weight of the polyester elastomer, the total content of silica and the polysiloxane compound is 22% or more in weight, the content of melamine cyanurate is 17% or more in weight, and the total content of silica, the polysiloxane compound, and melamine cyanurate is 45% to 53% in weight. The oxygen index of the resin composition is 26 or more. The number of times of circumferentially bending a test piece at 90 degrees around a 10 mm-diameter column in a repetitive bending test using the test piece made of the resin composition having a length of 50 mm, a width of 100 mm, and a thickness of 2.25 mm is 1000 or more.

  • Patent number: 7379288
    Abstract: The monolithic ceramic electronic component includes a first external electrode 5, a second external electrode 6, and a ceramic sintered compact 4 including internal electrodes 2 and 3, the first and second external electrodes 5 and 6 being disposed on both end faces 4a and 4b of the ceramic sintered compact 4. The first and second external electrodes 5 and 6 have a multilayer structure in which sintered electrode layers 5a and 6a, intermediate electroplated layers 5b and 6b, and plated layers 5c and 6c are arranged in that order. Exposed surface regions 7a of insulating oxides 7 are exposed from the outer faces of the sintered electrode layers 5a and 6a, the oxides 7 being derived from a glass frit contained in the sintered electrode layers. Metals 8 are deposited on the exposed surface regions 7a and the intermediate electroplated layers 5b and 6b are then formed by electroplating.
