Toroids are used to confine and guide magnetic fields.These doughnut-shaped forms are wrapped in a coil to create a substantial increase in magnetic field strength. The design allows a coil to be wound through the hole and around the outside.
The shape of the toroid also achieves the highest inductance per unit of volume, and helps to distribute the coil evenly around the circumference of the magnetic core. The continuous magnetic path yields the highest effective permeability and
lowest flux leakage of any shape.
Toroids are available in various diameters, thicknesses, permeability and types depending upon the frequency range of interest. They provide exceptionally high inductance for the physical space occupied, without interacting with adjacent components.
The ferri-magnetic compound ferrite is commonly used in toroids. Adams Magnetic Products is proud to represent and distribute the world’s best ferrite toroid core producers; Ferroxcube,
Epcos and
MMG.
These core producers are the most preferred by design engineers for the quality and reliability of their Nickel-Zinc and Manganese-Zinc ferrite materials.
Additionally, Adams carries a wide selection of ferrite toroid inventory including a broad range of sizes and permeability for power, signal, emi suppression applications and more.
Toroids are typically used in EMI filters, medical devices, musical instruments, amplifiers, power inductors and a wide array of transformers, including broadband, pulse and high frequency transformers.
