1. A method for producing a fuse (10), comprising the steps of:

  • providing at least one fuse element (12;

    12

    , 12

    ) having two connecting contacts (24

    , 24

    ) and an interposed conductive track (26), such that the conductive track (26) has a reduced line cross-section in relation to the connecting contacts (24

    , 24

    ) at least in some sections;

    providing a base support (14);

    providing the fuse element (12;

    12

    , 12

    ) with at least one overlay (16;

    16

    , 16

    ), wherein the fuse element (12;

    12

    , 12

    ) and the overlay (16;

    16

    , 16

    ) are each selected from materials which undergo diffusion when a predetermined ambient temperature is exceeded and when an electric current is conducted by the fuse element (12;

    12

    , 12

    ), andwherein the fuse element is being connected to an external component by a reflow soldering process without the fuse element triggering at a reflow soldering process temperature occurring in this process, wherein the reflow soldering process temperature is higher than thepredetermined ambient temperature, andarranging the at least one fuse element (12;

    12

    , 12

    ) on the base support (14),wherein the at least one overlay (16_1) is arranged within the conductive track (26_1) adjacent to one of the connecting contacts (24_1

    , 24_1

    ) of the fuse element (12_1).
