The present invention relates to a ceramic material for a multilayer capacitor. The ceramic material has a composition according to the following general formula:PbCaA(ZrTi)EFeNbWO, Further, the invention includes a capacitor comprising the described ceramic material.

Ceramic material for capacitor

A multi-layer capacitor including a capacitor element having at least two segments. Each segment includes multiple layer planes, including ceramic dielectric layers and electrode layers arranged therebetween, which are arranged in a layer sequence one above the other. The electrode layers include different electrodes, including at least first and second electrodes. The different electrodes overlap in active regions but not in passive regions. Multiple segments are arranged one above the other in a stack direction. The outermost dielectric layers of two segments form a connection region in which the segments are fixedly connected to each other parallel to the layer planes. The connection region contains a relief region. The relief region occupies at least the entire passive region of the capacitor.
