1. A broadband multilayer ceramic capacitor having a first end and a second end that is spaced apart from the first end in a longitudinal direction that is perpendicular to a lateral direction, the lateral direction and longitudinal direction each being perpendicular to a Z-direction, and wherein the capacitor comprises a top surface and a bottom surface opposite the top surface in the Z-direction, the broadband multilayer ceramic capacitor comprising:
a monolithic body comprising a plurality of dielectric layers stacked in the Z-direction;
a first external terminal disposed along the first end;
a second external terminal disposed along the second end;
a plurality of electrode regions that are stacked in the Z-direction, wherein the plurality of electrode regions comprises a dielectric region, an active electrode region, and a shield electrode region, wherein the active electrode region is located between the dielectric region and the shield electrode region in the Z-direction, and wherein the dielectric region extends from the active electrode region to the bottom surface of the broadband multilayer ceramic capacitor;
a plurality of active electrodes arranged within the active electrode region; and
at least one shield electrode arranged within the shield electrode region;
wherein:
the broadband multilayer ceramic capacitor has a capacitor length in the longitudinal direction between the first end and the second end, and the dielectric region is free of electrode layers that extend greater than 25% of the capacitor length from the first end or the second end; and
the broadband multilayer ceramic capacitor has a capacitor thickness in the Z-direction between the top surface and the bottom surface, the dielectric region has a dielectric region thickness in the Z-direction, and a ratio of the capacitor thickness to the dielectric region thickness is less than about 20.
