summarize
The telecommunication industry is one of the important markets of magnetic components.The most important applications are in filter inductors, delay circuits, impulse and impedance transformers.High Q value, good temperature stability and low loss are the necessary conditions for the filtration function.Pulse and signal transformers are often used in modern communications systems, such as integrated service digital network (ISDN) and asymmetric digital subscriber loop (XDSL) in digital networks.
