1. A component comprising:
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 damaging to the component,
wherein the connecting material has a melting point that is lower than the critical temperature, and
wherein the main body and the at least one external electrode are pressed against one another by a prestressing unit.
