Abstract
A transformer is configured to include a pair of cores and that each have an inner leg, wherein a primary winding that is wound around a bobbin having a hollow into which the inner legs of the cores and are inserted, and a secondary winding that has a hollow into which the inner legs of the cores and are inserted and that is constituted of a conductor formed by die-cutting a metal plate into a ring, are dispersedly arranged over the inner legs of the cores and. The bobbin has bobbin support portions that come into contact with a surface of a printed circuit board on which the transformer is implemented.
Claims16
A high-frequency transformer implemented on a printed circuit board, the high-frequency transformer comprising:
- a pair of cores that each include legs that define a magnetic path;
- and
- a primary winding and a secondary winding that are wound and provided in the legs,
- wherein at least one of the primary winding and the secondary winding is wound around a bobbin that includes support portions that come into contact with the printed circuit board.
A high-frequency transformer, comprising:
- at least one core having a first leg having a cylindrical shape and a second leg, the first leg and second leg defining a magnetic path;
- and
- a primary winding and a secondary winding surrounding the first leg and at least partially surrounded by the second leg,
- wherein at least one of the primary winding and the secondary winding is wound around a bobbin that includes support portions configured to be mounted on a printed circuit board.
