Ready to implement

Due to the steadily growing number of applications that are based on networked communication through data lines, it is becoming increasingly importan to ensure trouble-free operation and protection of electrical systems and devices.

To avoid reduced integrity of the data transfer due to interference and to pass EMC tests, components matched to the data lines are necessary. Implementation is greatly simplified by the filter bags, which contain filter components specially selected for the respective application.
