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.
