Abstract
Abstract A planar filter array includes a single monolithic alumina substrate having a plurality of counter bores on each side connected by central bores to form passages for insertion of connector pin contacts. The connecting bores contain ferrite beads and the counter bores contain discoidal capacitors which sandwich the ferrite beads to form pi filter circuits for filtering the pin contacts. Grounding electrodes on the discoidal capacitors are soldered to a grounding layer or traces on the substrate to provide a ground path for the fiters.
