Abstract:
A broadband multilayer ceramic capacitor may include a monolithic body including a plurality of dielectric layers stacked in the Z-direction, a first external terminal, and a second external terminal. A plurality of active electrodes, a bottom shield electrode, and a top shield electrode may be arranged within the monolithic body. The top shield electrode may be positioned between the active electrodes and a top surface of the capacitor and spaced apart from the top surface of the capacitor by a top-shield-to-top distance. A bottom shield electrode may be positioned between the active electrodes and the bottom surface of the capacitor and spaced apart from the bottom surface of the capacitor by a bottom-shield-to-bottom distance. A ratio of the top-shield-to-top distance to the bottom-shield-to-bottom distance may be between about 0.8 and about 1.2. The bottom-shield-to-bottom distance may range from about 8 microns to about 100 microns.
