Abstract

The present disclosure relates to an overvoltage-protection device for protecting a high-frequency terminal from overvoltage. Overvoltages can be compensated by a coil arrangement, which includes coils electrically in series with different, increasing inductances. The end of the relatively thinner coil is connected to the high-frequency terminal of a circuit.
