发明名称 SUBSTRATE AND ELECTRONIC DEVICE HAVING THE SAME
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a substrate with a capacitor mounted and an electronic equipment which can obtain a high a noise absorption performance and attain size reduction. <P>SOLUTION: The electronic equipment comprises a feedthrough capacitor 100 mounted on a surface of a substrate 12. A feedthrough electrode passes through a laminate 102. Outer electrodes 104a, 104b are electrically connected to both ends of the feedthrough electrode. A capacitor electrode defines the feedthrough electrode and a capacitance. A short-circuit electrode 24 is formed on back side or inside of the substrate body 13. Via hole conductors 22-1a, 22-1b are connected to the short-circuit electrode 24. The feedthrough electrode and the outer electrodes 104a, 104b constitute a first current path. The short electrode 24 and via hole conductors 22-1a, 22-1b constitute a second current path connected in parallel with respect to the first current path. <P>COPYRIGHT: (C)2009,JPO&INPIT</p>
