In an embodiment a multilayer varistor includes a ceramic body made from a varistor material, wherein the ceramic body includes a plurality of inner electrodes, first regions and second regions, wherein the varistor material in the first regions has a first average grain size D, wherein the varistor material in the second regions has a second average grain size D, and wherein D&#x3c;D.

Multilayer varistor having a field-optimized microstructure

A ceramic multi-layer component and a method for producing a ceramic multi-layer component are disclosed. In an embodiment a ceramic multi-layer component includes a stack with ceramic layers and electrode layers arranged between them, wherein the ceramic layers and the electrode layers are arranged above one another along a stacking direction, wherein at least one first electrode layer extends along a first main extension direction from a first end region to a second end region of the first electrode layer, and wherein the at least one first electrode layer has a current-carrying capacity that decreases along the first main extension direction.
