Substrate and Electronic Device Using the Same |
摘要 |
An electronic device which includes a feedthrough capacitor mounted on a front surface of a substrate. A feedthrough electrode penetrates a laminate (body of the capacitor). External electrodes are electrically connected to opposite ends of the feedthrough electrode. A capacitor electrode is disposed to form capacity in cooperation with the feedthrough electrode. A wiring conductor is formed on a rear surface of the substrate or inside the substrate, and via-hole conductors are connected to the wiring conductor. The feedthrough electrode and the external electrodes constitute a first current path. The wiring conductor and the via-hole conductors constitute a second current path electrically connected in parallel to the first current path.
