    摘要： An arrester and a method for producing an arrester are disclosed. In an embodiment the method includes providing at least three green layers, wherein each layer includes at least one green sheet, introducing at least one hole into a first layer and applying an electrically conductive material for forming inner electrodes to a second layer and a third layer. The method further includes laminating the layers to form a green stack, wherein the first layer is arranged between the second layer and the third layer, separating the green stack into individual components and compacting the individual components, wherein laminating the layers and compacting the individual components are effected in a single temperature process by co-firing.

    摘要： A piezoelectric transformer and a method for producing a piezoelectric transformer are disclosed. In an embodiment, the method includes manufacturing a main body having an input region having electrodes and a first piezoelectric material being alternately stacked one on top of the other. An output region includes a second piezoelectric material. The first piezoelectric material is polarized and a removable contact is fitted to an output-side end side of the main body, which end side faces away from the input region. A first electrical potential is applied to the removable contact for polarizing the second piezoelectric material.
