发明名称 LC filter structure
摘要 An LC filter comprises a ceramic laminate which has at least one dielectric part defining an exposed surface and at least one magnetic part integrated with the dielectric part in a layered manner. The ceramic laminate is provided with at least one through hole which has a first opening positioned on the exposed surface of the dielectric part and commonly passes through both of the dielectric part and the magnetic part. A connector pin is inserted in the through hole while a first electrode of a capacitor is formed on the exposed surface in a peripheral region of the first opening to be electrically connected with the connector pin. A second electrode of the capacitor is provided to be opposite to the first electrode through a dielectric member forming the dielectric part except for a peripheral region of the through hole, so that the second electrode is extracted toward the exterior of the ceramic laminate as a grounded electrode.
