Abstract (en)

[origin: EP0798750A2] The resistance has a pair of parallel terminal electrodes (1,2) in flat contact with a resistance body (3) which has a positive temperature coefficient characteristic. A varistor (40) lies in electrical contact with the resistance body which has 2 contact surfaces (50,51). The response point (60) of the resistance body is connected in parallel with the varistor through the surfaces. A number of series connected varistors (41,42,43,44) may contact respective meanders of a zigzag resistance body between the parallel terminal electrodes via respective contact surfaces (52,53).
