1. A multilayer ceramic capacitor, the multilayer ceramic capacitor comprising:
a monolithic body comprising a plurality of dielectric layers stacked in a Z-direction that is perpendicular to a longitudinal direction, the monolithic body having a first end and a second end that is spaced apart from the first end in the longitudinal direction;
a first plurality of electrodes extending from the first end towards the second end of the monolithic body, the first plurality of electrodes being spaced apart from the second end of the monolithic body by a first margin distance;
a second plurality of electrodes extending from the second end towards the first end of the monolithic body, the second plurality of electrodes being spaced apart from the first end of the monolithic body by a second margin distance;
a first external termination disposed along the first end and connected with the first plurality of electrodes, the first external termination comprising a compliant layer including a conductive polymeric composition; and
a second external termination disposed along the second end and connected with the second plurality of electrodes;
wherein:
the monolithic body has a body length in the longitudinal direction between the first end and the second end and a margin ratio between the body length and at least one of the first margin distance or the second margin distance is less than about 10;
the compliant layer has a maximum thickness in the longitudinal direction and a ratio of the first margin distance to the maximum thickness of the compliant layer is greater than about 5; and
an average thickness of the compliant layer is greater than 10 μm.
