Patent ID: 6982608

Claim:
An isolator, comprising: a flat plate-shaped ferrite member; first, second, and third central conductors located on the ferrite member on different planes in a vertical direction with dielectric bodies sandwiched therebetween so that parts thereof cross each other in the vertical direction; a magnet arranged on the central conductors; a first yoke arranged so as to cover the magnet; and a second yoke arranged on the bottom face of the ferrite member to constitute a magnetic closed circuit together with the first yoke, wherein the ferrite member is substantially rectangular-shaped having long sides and short sides, and wherein one of the central conductors contacts one of the long sides and is arranged transverse to a short surface of the ferrite member at an oblique angle to the short sides, and is longitudinally divided to form first and second conductors, the first and second conductors having different widths.
