Abstract
A surge absorbing circuit has a substrate on which a first conductor, a second conductor, and a third conductor are placed, and a surge absorber having a first terminal and a second terminal. The first conductor and the second conductor are mutually coupled in a polarity-reversed relation. One end of the first conductor is connected to one end of the second conductor. The third conductor is electrically isolated from the first conductor and the second conductor on the substrate. The first terminal of the surge absorber is connected to a connection portion between the first conductor and the second conductor. The second terminal of the surge absorber is connected to the third conductor.
Claims10
A surge absorbing circuit comprising:
- a substrate on which a first conductor, a second conductor, and a third conductor are placed;
- and
- a surge absorber having a first terminal and a second terminal,
- wherein the first conductor and the second conductor are mutually coupled in a polarity-reversed relation, and one end of the first conductor is connected to one end of the second conductor,
- wherein the third conductor is electrically isolated from the first conductor and the second conductor on the substrate,
- wherein the first terminal of the surge absorber is connected to a connection portion between the first conductor and the second conductor, and the second terminal of the surge absorber is connected to the third conductor, and
- wherein an inductance component of the first conductor is placed substantially entirely on a layer of the substrate and an inductance component of the second conductor is placed substantially entirely on a different layer of the substrate.
