EMC filter components based on soft magnetic filled plastics

With the help of new materials, new passive electronic components (capacitances and inductances) can be developed. These are flexible and remote from standard geometries. It is necessary to examine the newly developed materials with regard to their producibility, as well as thermal and electromagnetic properties. To this end, new component structures are selected and produced by means of field simulation programs. With the help of new techniques, new components are to be developed and built up for special mechatronic systems, e.g. voltage transformers or certain EMC filters, which allow for an optimal utilization of complicated structural space geometries.

Project Targets

Development of novel passive electronic components that can be integrated with high structural flexibility.


Material optimization in the stress field of processability, as well as mechanical and electro-magnetic properties

Material characterization

Development of novel component structures that take feasibility, reliability and electrical targets into consideration


After completion of the project, newly developed EMC filter components were successfully developed into a complex mechatronic system for driving a hybrid vehicle.
