Abstract: An electronic circuit in which resistors R.sub.0 . . . R.sub.n+m are coupled in series with fusible cut-outs Q.sub.0 . . . Q.sub.n+m and in which at least one fusible cut-out Q.sub.n+1 . . . Q.sub.n+m is bridged by an additional resistor R.sub.n+1 ' . . . R.sub.n+m '. Each of the fusible cut-outs Q.sub.0 . . . Q.sub.n+m can be blown from a conductive to a non-conductive state. The total conductance Y.sub.total of the electronic circuit can thus be adjusted by targeted blowing of individual ones of the fusible cut-outs Q.sub.0 . . . Q.sub.n+m.
