Abstract:
A laminated capacitor comprising:a capacitor body having first and second major surfaces and including a laminated stack of a plurality of dielectric layers, at least a pair of a first and second internal electrodes opposed to each other with at least one of the dielectric layers being disposed therebetween; a plurality of first feedthrough conductors perforating through at least one of the dielectric layers provided within the capacitor body, the first feedthrough conductors being electrically insulated from the second internal electrodes and electrically connected to the first internal electrodes; and a plurality of second feedthrough conductors perforating through the capacitor body and provided within the capacitor body, the second feedthrough conductors are electrically insulated from the first internal electrodes and are electrically connected to the second internal electrodes, the first and second feedthrough conductors are arranged to offset the magnetic fields induced by the electric current flowing through the internal electrodes; a plurality of first external terminal electrodes arranged so as to correspond to the respective first feedthrough conductors and electrically connected to respective ones of the first feedthrough conductors; and a plurality of second external terminal electrodes, which are arranged to correspond to respective ones of the second feedthrough conductors and electrically connected to respective ones of the second feedthrough conductors; wherein the first external terminal electrodes are located at least on the first major surface of the capacitor body and extend substantially parallel to the internal electrodes, and the second external terminal electrodes are located on both the first major surface and the second major surface in opposed relation to the first major surface.
