ABSTRACT:
A multilayer feedthrough capacitor array is provided with a capacitor element, and first to sixth terminal electrodes. The capacitor element has a plurality of laminated insulator layers, a first signal internal electrode and a first ground internal electrode disposed so as to face each other with the insulator layer in between, and a second signal internal electrode and a second ground internal electrode disposed so as to face each other with the insulator layer in between. The first signal internal electrode includes a first signal lead portion electrically and physically connected to the first terminal electrode, and a second signal lead portion electrically and physically connected to the second terminal electrode. The first ground internal electrode includes a first ground lead portion electrically and physically connected to the fifth terminal electrode, and a second ground lead portion electrically and physically connected to the sixth terminal electrode. The second signal internal electrode includes a third signal lead portion electrically and physically connected to the third terminal electrode, and a fourth signal lead portion electrically and physically connected to the fourth terminal electrode. The second ground internal electrode includes a third ground lead portion electrically and physically connected to the fifth terminal electrode, and a fourth ground lead portion electrically and physically connected to the sixth terminal electrode. The first signal internal electrode and the second ground internal electrode are disposed so as not to face each other with the insulator layer in between, and the second signal internal electrode and the first ground internal electrode are disposed so as not to face each other with the insulator layer in between.
