An electrical component comprises a main body and at least one external electrode that is fastened by a connecting material to the main body. The main body and the external electrode have different coefficients of thermal expansion that determine a critical temperature which, when exceeded, results in a connection between the main body and the external electrode experiencing mechanical stresses that lead to damage to the component. The connecting material has a melting point which is lower than a critical temperature.
