Toroidal Ferrite Core
The toroidal ferrite core uses a toroidal (ring or donut) shape ferrite core, which has the characteristics of isolating eddy current, low permeability, and suppressing interference. Due to the superior electrical performance of the ring, the usage of toroidal ferrite core is greatly increased
We provide toroidal ferrite cores in different sizes. You can use it in power transformers, current transformers, instrument transformers, inductors, chokes, ballasts, voltage stabilizers, welding transformers, broadband transformers, filters, etc. You can choose the bottle size that best suits your needs. In addition, if what you need is not in the list, please feel free to contact us. We can help you customize the toroidal ferrite core.

Introduce of T-core
Toroid cores are the core type geometry of choice for optimizing performance. 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. The symmetry of T cores circular geometry minimizes the amount of external magnetic flux produced. Consequently T cores produce much lower amounts of unwanted electromagnetic interference. 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. Cooler windings result in higher efficiency and may allow more utilization of the core’s capability. Because of its circular nature, the magnetic path of a T-core is an unbroken continuous path unless intentionally broken. There is no air gap in the magnetic path (unless intentionally added) hence optimal use can be made of high permeability materials. Toroids are manufactured in practically all “soft” magnetic materials. 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). Some toroid cores are “boxed” to provide isolation, because the core material is sensitive to stresses produced by the winding processes. MnZn Power and High Permeability Toroidal Ferrite Cores
