An avionics housing has electrical connectors mounted centrally on a front face. Transient voltage suppressors are located in an array of holes in a metal plate to each side of the connectors, beneath removable panels so that they are accessible on the front face after removal of the panels. The suppressors extend through the plate to connect with circuit boards on the opposite side that have tracks connecting with the connectors. A filter module is secured behind the circuit boards and supports filters that connect with connections on the boards. A rear connection assembly carries connectors on its rear surface by which connection is made to circuits within the unit. Flexi-rigid circuits interconnect the rear connectors with socket array boards on the front of the rear connection assembly and these, in turn, connect with contacts on the filter module.
