Abstract
A data carrier ( ) comprises an integrated circuit ( ), which integrated circuit ( ) comprises a tolerance-defined main capacitor ( ) which is connected to a coil ( ) of the data carrier ( ), and which integrated circuit ( ) comprises at least one integrated additional capacitor ( ) which is optionally connectable to the coil ( ) of the data carrier ( ) so that a parallel switching configuration of the main capacitor ( ) with the at least one additional capacitor ( ) is achievable. The optional parallel arrangement of the at least one additional capacitor ( ) leads to a reduction of the tolerance range of the nominal capacitance of the main capacitor ( ) when the effectively realized capacitance of the main capacitor ( ) is reduced by a factor F and the at least one additional capacitor ( ) has a fraction K of the nominal capacitance of the main capacitor ( ).
