Common mode inductor, also known as Common mode Choke, is commonly used to filter Common mode EMI signals in switching power supplies of computers. In-board card design, a common-mode inductor also plays the role of an EMI filter, which is used to suppress the electromagnetic wave emitted by high-speed signal lines.
Toroidal Inductors provide a number of advantages over other inductor varieties

The choke's impedance increases with frequency. Its low electrical resistance passes both AC and DC with little power loss, but its reactance limits the amount of AC passed. The above is about the choke coils' introduction
Toroidal Inductors are a highly economical choice. Efficient Design- Inductor designers can achieve shorter lengths of turn with smaller-sized Toroidal Inductors using less copper wire and with no bobbin as with E-core designs.
