摘要： A multi-terminal monolithic ceramic capacitor arranged to reduce an equivalent series inductance and having an array structure is provided. A first same-polarity-connection conductor and a second same-polarity-connection conductor are provided inside a capacitor body so as to extend over at least two capacitors. The first same-polarity-connection conductor is electrically connected to a plurality of first external terminal electrodes, and the second same-polarity-connection conductor is connected to a plurality of second external terminal electrodes. In the monolithic ceramic capacitor which is mounted on a wiring substrate, the overall capacitance can be maintained even if an accident, such as cracking of a solder joint, occurs in one of the external terminal electrodes.

摘要： In a multilayer capacitor including a capacitor body, first capacitor portions and a second capacitor portion are arranged in the direction of lamination. While a resonant frequency of the first capacitor portions is set to be greater than a resonant frequency of the second capacitor portion so that the first capacitor portions contribute to low impedance, an ESR per layer of the second capacitor portion is set to be greater than an ESR per layer of the first capacitor portions so that the second capacitor portion contributes to high ESR. Further, a combined ESR of the first capacitor portions is set to be substantially equal to a combined ESR of the second capacitor portion.

摘要： A monolithic capacitor includes a main capacitor unit having first capacitor portions and a second capacitor portion arranged in a direction of lamination, with the first capacitor portion located towards at least one end in the direction of lamination, so that the first capacitor portion is located closer to a mounting surface than the second capacitor portion. The number of pairs of third and fourth lead-out portions for third and fourth internal electrodes in the second capacitor portion is less than the number of pairs of first and second lead-out portions for first and second internal electrodes in the first capacitor portion, so that the first capacitor portion contributes to decreasing ESL while the second capacitor portion contributes to increasing ESR.

摘要： An insulation displacement terminal is formed entirely of an integral metal sheet. The terminal includes first and second plate-like insulation displacement groove-forming portions opposed to each other in a first direction along which an insulated wire extends. Each of the insulation displacement groove-forming portions has an insulation displacement blade of a U-shape defining an insulation displacement groove. Bottom portions of the insulation displacement groove-forming portions are interconnected by an interconnecting portion. A lead extends downwardly from one side edge of the interconnecting portion. A holding space for an insulation of the insulated wire is formed between a pair of plate portions which are formed respectively at opposite side edges of the first insulation displacement groove-forming portion by bending. Each of the plate portions has a retaining projection and a bendable piece portion.

摘要： This invention aims to provide a process for producing an oxide-dispersion strengthened platinum material which allows zirconium oxide to be more finely dispersed in a platinum material, and to further improve creep strength in an oxide-dispersion strengthened platinum material. This invention provides a process for producing an oxide-dispersion strengthened platinum material where zirconium oxide is finely dispersed in platinum, wherein powdered platinum is poured into water to prepare a platinum suspension; a zirconium nitrate solution and an urea solution are added in the platinum suspension for adjusting the suspension to a given pH to precipitate zirconium hydroxide and thus to form a zirconium hydroxide carrying platinum; the zirconium hydroxide carrying platinum is collected, which is then formed into a molding; the molding is sintered and forged under the conditions whereby secondary recrystallization growth in a platinum crystal proceeds, to form a platinum ingot; and the platinum ingot is cold-rolled in a processing rate of at least 70% and then the product is thermally recrystallized.

摘要： In the temperature of 70-140 degrees C., the burn-in process of applying a voltage to monolithic ceramic capacitors so that the strength of the electric field applied between the internal electrodes opposing each other may be 7 30 kV/mm is performed. Subsequently, the insulation resistance of the monolithic ceramic capacitor is measured. The monolithic ceramic capacitors are sorted based on the insulation resistance measured during this insulation-resistance measurement process. In this case, it is sufficient to apply the burn-in process for 2-300 seconds.
