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, 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, eg voltage transformers or certain EMC filters, which allow an optimal utilization of complicated structural space geometries.
