摘要：
An electroacoustic component is specified in which the disturbing contributions of undesired wave modes are reduced. For this purpose, a component comprises includes a piezo layer, an electrode layer and a separating layer. A main mode and a secondary mode are capable of propagation in the component. The separating layer has an opposite thickness dependence for the frequencies of the main mode and of the secondary mode.
