Abstract:
A filter circuit has first and second varistors, a resistance, an input terminal, an output terminal, and a ground terminal. The resistance is connected between the first and second varistors. The input terminal is connected to a junction between the first varistor and resistance through a first coil. The output terminal is connected to a junction between the second varistor and resistance through a second coil. The ground terminal is connected to a side of the first varistor opposite from the resistance and a side of the second varistor opposite from the resistance.
