Abstract

The electric ceramic component has a main part ( 9 ) made of a dielectric material, an active region ( 3 ) being disposed in said main part. At least one outer contact ( 1, 1 ′) is arranged on the main part. A feed line region ( 2, 2 ′) connects the outer contact to the active region. An electrode ( 4, 4′, 5, 5′, 6, 6′ ) is arranged in the main part so as to adjoin the feed line region and is connected to the outer contact in an electrically conductive manner but not to the active region.

First claim

The invention claimed is:

1. An electric ceramic component comprising:
a base body of a dielectric material, in which an active region is arranged;
an outer contact, which is arranged on the base body;
a further outer contact, which is arranged on the base body on an opposite side with respect to the outer contact;
a supply region, which connects the outer contact to the active region;
a further supply region, which connects the further outer contact to the active region;
an electrode, which is arranged next to the supply region in the base body and is electrically conductively connected to the outer contact, but not to the active region, the electrode electrically shielding the supply region;
a further electrode, which is arranged next to the further supply region in the base body and is electrically conductively connected to the further outer contact, but not to the active region, the further electrode electrically shielding the further supply region;
a central outer contact, which is arranged on the base body between the outer contact and the further outer contact;
a central supply region, which connects the central outer contact to the active region; and
a central electrode, which is arranged next to the central supply region in the base body and is electrically conductively connected to the central outer contact, but not to the active region, the central electrode electrically shielding the central supply region.

2. The electric ceramic component of claim 1 , further comprising:
a further central outer contact, which is arranged on the base body on an opposite side with respect to the central outer contact;
a further central supply region, which connects the further central outer contact to the active region; and
a further central electrode, which is arranged next to the further central supply region in the base body and is electrically conductively connected to the further central outer contact, but neither to the active region nor to the central electrode.

3. The electric ceramic component of claim 1 or 2 , further comprising:
a plurality of further electrodes, which are arranged next to the supply region in the base body and are electrically conductively connected to the outer contact, but not to the active region,
the plurality of further electrodes being plates arranged in parallel at distances from one another, and
the electrode and the plurality of further electrodes being arranged on sides of the supply region where the supply region adjoins neither the outer contact nor the active region, thus shielding the supply region.

4. The electric ceramic component of claim 3 , further comprising:
a further plurality of further electrodes being arranged next to the further supply region in the base body and electrically conductively connected to the further outer contact, but not to the active region,
the further plurality of further electrodes being plates arranged in parallel at distances from one another, and
the further electrode and the further plurality of further electrodes being arranged on sides of the further supply region where the further supply region adjoins neither the further outer contact nor the active region, thus shielding the further supply region.
