A ceramic multilayer component has a base body with connecting contacts, fitted to it, with a ferrite ceramic, which is provided for an inductive area and in which an inductance is arranged which is formed by electrical conductors, and with a varistor ceramic, wherein the varistor ceramic comprises at most 40% of the volume of the base body.

Ceramic multilayer component

A multilayer component includes a dielectric ceramic material that can be co-sintered with a varistor ceramic to form a monolithic multilayer component according to the invention. The multilayer component therefore includes a layer of a varistor ceramic and another layer of a dielectric. Both layers can be arranged directly adjacent to one another in the multilayer component. In the multilayer component, metallizations are arranged on or between the ceramic layers. The metallizations are structured to form conductor sections and metallized areas. The metallizations form together with the ceramic layers alongside a varistor at least one further component selected from at least one of the component functions.

Multilayer component and production method

A multi-layered component is disclosed, including at least one inductive region, wherein the inductive region includes a ferrite ceramic. The inductive region has electrode structures that form at least one inductance. The multi-layered component has at least one capacitive region, wherein at least one capacitive region includes a varistor ceramic. The capacitive region forms at least one capacitance. At least one inductive region and at least one capacitive region form at least one LC filter.
