Abstract
According to one embodiment, an isolator includes an isolator module, the isolator module including: a first coil and a second coil, each being helically shaped and having a central axis that extends in a first direction; and a first insulator configured to seal the first coil and the second coil, wherein the first coil and the second coil are separated from each other, and the first coil is positioned inside the second coil when viewed in the first direction.

An isolator comprising an isolator module, the isolator module comprising:
- a first coil and a second coil, each being helically shaped and having a central axis that extends in a first direction;
- a first insulator configured to seal the first coil and the second coil;
- a first pad coupled to a top surface of the first coil at an upper end of the first coil;
- a second pad coupled to a bottom surface of the first coil at a lower end of the first coil;
- a third pad coupled to a top surface of the second coil at an upper end of the second coil;
- a fourth pad coupled to a bottom surface of the second coil at a lower end of the second coil;
- a first chip;
- and
- a second chip,
- wherein the first coil and the second coil are separated from each other,
- the first coil is positioned inside the second coil when viewed in the first direction,
