Abstract:
1. A surge absorber comprising: a first terminal electrode; a second terminal electrode; a third terminal electrode; an inductor portion having a first internal conductor and a second internal conductor mutually coupled in a polarity-reversed relation such that current through the first and the second internal conductors, respectively, flow in the same direction, wherein one end of the first internal conductor is connected to the first terminal electrode, one end of the second internal conductor is connected to the second terminal electrode, and an other end of the first internal conductor is connected to an other end of the second internal conductor; a surge absorbing portion having a first internal electrode connected to the other end of the first internal conductor and to the other end of the second internal conductor, and a second internal electrode connected to the third terminal electrode; and a resistor portion having a DC resistance component connected between the first terminal electrode and the second terminal electrode, wherein the resistor portion has a first DC resistance component connected between the first terminal electrode and the first internal electrode, and a second DC resistance component being larger than the first DC resistance component and connected between the first internal electrode and the second terminal electrode.
