Abstract
Abstract A planar filter array is completely isolated from mechanical and thermal stresses by an arrangement of resilient planar gaskets which sandwich said array and electrical contact springs which also serve to isolate the array from mechanical and thermal stresses and which permit electrical connection of the individual filters in the array to external devices. The filter array and gaskets are inserted into a housing to form a filtered electrical connector, the filters in the array being connected to the housing via grounding springs and to connector pins via contact springs placed in apertures in the array. The filters may be simple capacitive filters or pi filters formed of cylindrical ferrite inductors sandwiched between the capacitor arrays and embedded in a resilient planar gasket.
