摘要

Capacitor comprises two or more electrode layers (1) lying opposite each other with dielectric layers (2) between them. The dielectric layers are made of a ceramic material containing two different components in a phase different from the other. The components have a perovskite structure with silver on the A positions and niobium and tantalum on the B positions. Components A and B are selected so that the temperature coefficients of their dielectric constants have different polarities in a temperature range. - Preferred Features: The dielectric layers have a thickness of 1-50 microns . The ceramic material contains boric acid as sintering aid.
