Toroidal Transformers

MSI Toroidal Transformer
Due to their unique construction and geometry, toroidal transformers offer many advantages over more traditional E-I and stacked laminated cores.  Because of the magnetic properties of the ring shaped core, toroidal transformers offer lower core loss, excitation current, and less magnetic leakage.  They are also physically quieter, since there are no core laminations to vibrate.
