T cores are widely applied in Power, Current transformer and Telecom field. Some toroid cores are 'boxed' to provide isolation, because the core material is sensitive to stresses produced by the winding processes. Toroid Cores can be coated with insulation like powder coating core and parylene coated core to provide electrical isolation between the core and the winding(s). Toroids are manufactured in practically all 'soft' magnetic materials. There is no air gap in the magnetic path (unless intentionally added) hence optimal use can be made of high permeability materials. Because of its circular nature, the magnetic path of a T-core is an unbroken continuous path unless intentionally broken. Cooler windings result in higher efficiency and may allow more utilization of the core's capability. Compared against other core types, a toroidal coil has a lot of surface area from which it can dissipate heat hence it cools much better than other core types. Consequently T cores produce much lower amounts of unwanted electromagnetic interference. The symmetry of T cores circular geometry minimizes the amount of external magnetic flux produced. A toroid of round cross-section offers better performance than one of rectangular cross-section, but for practical and economic reasons, toroid cores of rectangular cross-section are much more prevalent. Toroid cores are the core type geometry of choice for optimizing performance.
