  • Resistor which is designed in the form of a column and is resistant to high current in particular a varistor on a metal-oxide base, and method for producing such a resistor
    Patent number: 6342828
    Abstract: The resistor is designed in the form of a column and has a cylindrical resistor body which is arranged between two planar electrodes, aligned parallel, and is made of a ceramic material. The resistor is preferably a varistor on a metal-oxide base, and is then used as a voltage-limiting element in an overvoltage suppressor. The strength of the ceramic material and the length of the resistor are chosen to be as great as possible. However, the length of the resistor is at most sufficiently large that damage to the ceramic resistor body caused by thermally produced pressure waves is avoided when the resistor is loaded in an electrical field of given magnitude with at least one highly energetic current pulse of defined amplitude, form and duration.
