Toroidal Inductors are used for applications that include current sense transformers, common mode inductors, switching regulator inductors, input filter inductors, and more. These inductors provide excellent value — they are generally smaller in size and cost less than other inductors.
Toroidal Inductors provide a number of advantages over other inductor varieties, which include:
Compact Size — The smaller size of Toroidal Inductors allows for excellent efficiency while maintaining top level performance.Lower Cost — With smaller sizes that use less raw materials, Toroidal Inductors are a highly economical choice.
Efficient Design — Inductor designers can achieve shorter length of turn with smaller-sized Toroidal Inductors using less cooper wire and with no bobbin as with E-core designs.
