In the data and signal transmission it is important to ensure electromagnetic compatibility.

• The number of systems being used for the acquisition, processing and distribution of data is continuously growing.
• Microelectronics are spreading into new fields of application (e.g. automotive electronics)
• The growing popularity of xDSL with its high transmission rates and worldwide networls has led to new EMC problems

Chokes are a very effective means of protecting data lines. The different designs, optimized for telecommunications and data applications, exhibit very low stray inductance and excellent symmetry features. They can substantially enhance the characteristic symmetry of a transmission line and thus cintribute further to increasing interference immunity and at the same time reducing emitted interference.
