Advantages of Toroidal Windings
 

In general, a toroidal inductor/transformer is more compact and lighter than other shaped cores. This is especially the case for power devices.

Because the toroid is a closed-loop core it will have a higher magnetic field and thus higher inductance and Q factor than an inductor of the same value with a straight core (solenoid coils). This is because most of the magnetic field is contained within the core. By comparison, with an inductor with a straight core, the magnetic field emerging from one end of the core have a long path through air to enter the other end.

In addition, because the windings are relatively short a toroidal transformer will have a lower secondary impedance which will increase efficiency and electrical performance.

Due to the symmetry of a toroid, little magnetic flux escapes from the core (leakage flux). Thus a toroidal inductor/transformer, radiates less electromagnetic interference (EMI). Manufacturers have adopted toroidal coils in recent years to comply with increasingly strict international standards limiting the amount of electromagnetic field consumer electronics can produce.
