Abstract
Abstract A compact EMP and EMI/RFI connector protection module insertable into a connector receptacle forming a portion of a sealed electrical enclosure. The protection modules include a plurality of electrical filters each protecting a pin such as a 300 plus pin ARINC 600 connector standard on aircraft electronic enclosures or boxes. The modules comprise a conductive lattice or grid having a plurality of orifices defined by facing walls. Unpackaged integrated circuit dies are bonded to the walls defining the orifices and are electrically coupled to inserted contact pins via spring clips inserted therebetween. A conductive path exists from the pins to the conductive lattice, forming a ground plane and a heat sink, via the unpackaged integrated circuit die, a conductive strip and spring clip. The module is sufficiently compact providing electrical protection to selected pins on 0.1 inch centers.
