Electronic components incorporating capacitors

摘要

An electronic component comprising a discoidal, multi-layer, multi-composition capacitor, which capacitor is fabricated by stacking and co-firing a plurality of differing ceramic composition layers between a plurality of metallic electrodes to form a ceramic block, the ceramic composition layers having been selected so that the compositions are compatible for co-firing and also so that each layer of a different composition exhibits a respective peak in its permittivity at a different temperature, from that of the other compositions, within a selected temperature range, wherein the number of layers and thickness of layers for each composition is selected such that the total capacitance becomes substantially equal across the complete selected temperature range when the layers are connected in parallel within the ceramic block, and wherein the disc shape of the capacitor is formed from the ceramic block before it is incorporated in the electronic component. <IMAGE> <IMAGE>
