ABSTRACT:
The invention relates to a high-pass branch (7) of a frequency separating filter for ADSL systems comprising inductive components (11, 14) which dispose of magnet cores made of a soft magnetic amorphous or nanocrystalline. As a result, frequency separating filters are provided which comprise small structural shapes and which have especially beneficial properties in the relevant frequency and temperature range.
