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 S2, and a total equal to S2 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 S1, S1 is equal to or greater than about 1.3 times S2. 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.
