T18*28*10 Common Mode Chokes DW4395

Common mode Choke is commonly used in computer switching power supplies to filter common mode electromagnetic interference signals. In the board design, the common mode inductor also acts as an EMI filter to suppress the electromagnetic radiation generated by the high-speed signal line from radiating outward.

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.
