ABSTRACT:
A piezoelectric component has a multilayer structure. The piezoelectric component includes piezoelectric ceramic layers, electrode layers arranged among the ceramic layers in a stack such that the electrode layers and the piezoelectric ceramic layers alternate in the stack, and a passivation layer disposed on a lateral surface of the stack. The passivation layer is made from a passivation material that has a crack resistance that is lower than a bond strength of the passivation material.
