Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A ceramic multilayer component comprising: a base body with connecting contacts, fitted to it, a ferrite ceramic, which is provided for an inductive area in the base body and in which an inductance is arranged which is formed by electrical conductors, and a varistor ceramic in the base body, wherein the varistor ceramic comprises at most 40% of a volume of the base body, wherein the varistor ceramic further includes a stratum layer of a surface varistor, and wherein the surface varistor which makes up a part of the at most 40% of the volume of the base body comprises at most 20% of the volume of the base body. 2. The multilayer component according to claim 1 , in which the varistor ceramic comprises a ZnO—Bi—Sb ceramic or a ZnO—Pr ceramic. 3. The multilayer component according to claim 1 , in which the connecting contacts are provided for a ball grid array or a land grid array. 4. The multilayer component according to claim 1 , in which a metallic or oxidic intermediate layer is arranged between the ferrite ceramic and the varistor ceramic. 5. The multilayer component according to claim 1 , in which the varistor ceramic provides an ESD protection function. 6. The multilayer component according to claim 1 , in which the varistor ceramic together with the connecting contacts forms a capacitance. 7. The multilayer component according to claim 6 , in which the inductance and the capacitance form an LC filter. 8. The multilayer component according to claim 1 , in which the ferrite ceramic comprises an NiZn ferrite, NiCuZn ferrite, NiZnCo ferrite, NiCuZnCo ferrite or hexagonal ferrite.
