Abstract
A ceramic condenser module includes at least one first multi-layered ceramic condenser and at least one second multi-layered ceramic condenser, which are mounted to a front surface and a back surface of a substrate, respectively. When a total surface area of the outside surfaces of the mounted first and second multi-layered ceramic condensers excluding surfaces thereof opposing the substrate is defined as S , and a total equal to S and a surface area of the outside surface of the substrate excluding the area covered by the first and second multi-layered ceramic condensers is defined as S , S is equal to or greater than about 1.3 times S . With this arrangement, the ceramic condenser module is suitable for use with large amounts of current, has excellent heat-dissipation effect, is much smaller and much less expensive.
