The different designs of inductors, such as coils on toroidal cores and those on molded cores, each have their own advantages, as does the respective core material (ferrite, iron filings, composite). There are also inductors that combine the advantages.
Transformers and transformers have the same technical basis: magnetically coupled inductors. They can transmit the smallest analog and switching pulses as well as the highest powers. The actual implementation varies depending on the application: while signal transformers are intended to transmit the signal form as accurately and promptly as possible, transformers are concerned with keeping power losses as low as possible.
We cover all application purposes with a wide variety of products. All designs are also available as SMD.
