Abstract
A magnetic core for use with a printed circuit board transformer can include one or more inside corners of the magnetic core formed to include a curved channel that serves as a strain relief and facilitates positioning a printed circuit board within a core window defined by the core. The magnetic core can be an E-core. A center post of the E-core can define a notch configured to receive a complementary tab of a printed circuit board of the printed circuit board transformer. A center post of the E-core can be shorter than outside legs of the E-core, so that when assembled with an I-core a resulting core has an air gap. The core can be made of a ferrite material. A printed circuit board transformer can include a printed circuit board having one or more turns of a conductive trace disposed thereon and a magnetic core as described above.
