Toroidal Inductor

Ferrite Core (12.7 x 7.9 x 6.35mm)

Toroidal inductors use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components, consisting of a circular ring or donut shaped magnetic core of ferromagnetic material such as laminated iron, iron powder, or ferrite, around which wire is wound.

The advantage of the toroidal shape is that, due to its symmetry, the amount of magnetic flux that escapes outside the core (leakage flux) is low; therefore it is more efficient and thus radiates less electromagnetic interference (EMI).

Toroidal inductors are used in a wide range of electronic circuits: power supplies, inverters, and amplifiers. They are also commonly used in the construction of electronic projects such as a Joule Thief which extracts as much power from a seemingly entirely used 1.5v battery.
