Q.Are there any problems in mounting common mode filters / chokes for signal lines?

EMC Components >  EMC Components >  Common Mode Filters / Chokes

A. There is no problem using common mode filters (common mode chokes) for power sources in signal lines.
However, if you wish to use common mode filters or chokes for signal lines in a DC line (not recommended), please pay attention to the rated current, etc.
Please refer to the Selection Guide published by TDK in order to confirm products based on the usage method.
