Abstract: An multilayered ceramic capacitor is provided with mitigated microphonic noise propagation. The multilayered ceramic capacitor comprising a body comprising at least one face wherein the face has a body length. Parallel internal electrodes of alternating polarity are in the body wherein each internal electrode has a tab integral thereto wherein adjacent tabs are not in registration and alternate tabs are in registration. A dielectric is between adjacent internal electrodes. External terminations wherein a first external termination are in electrical contact with first tabs in registration and a second external termination is in electrical contact with second tabs in registration wherein the first external termination and second external termination are on the face and separated by a termination separation. A ratio of the termination separation to the body length is no more than 0.6 and the body comprises an extended portion beyond the external terminations.

Abstract: An electronic component with a self-damping MLCC is provided. The electronic component comprising a pulse signal generator and a substrate comprising first traces and second traces. An MLCC is provided comprising a first capacitive couple between two first external terminations and a second capacitive couple between two second external terminations wherein each first external termination is in electrical contact with a different first trace and each second external termination is in electrical contact with a different second trace. The pulse signal generator provides a first pulse to the first traces and a second pulse to the second traces wherein the first pulse and second pulse are not in phase.

Abstract: An MLCC with an identification mark consisting of non-active internal electrodes which can be used to determine chip orientation for mounting or reeling. This allows an MLCC with substantially similar width and thickness to be oriented with the electrodes in a preferred direction (either vertical or horizontal with respect to the board) that results in the minimum noise and vibration compared to other orientations. The presence of an identification mark can also allow for a means of preferentially orienting an MLCC which has an active area that is offset from the geometric center of the part.
