Abstract: A transient suppression connector which is a self-contained unitary assem having the transient suppression components connected between the electrical cable and the electronics package case. A connector adaptor about the electrical connector at the end of the cable is attached to the package case. An adaptor plate connected to the connector adaptor supports the electronic circuit board within the package. The transient suppression components are connected between a ground plane and a circuit board contained within the connector adaptor, the ground plane being electrically connected via the connector adaptor to the package case. The pins of the electrical connector extend through the suppression circuit board to the electronic circuit board, being electrically connected to both. Thus, the transient suppression components are connected between the electrical connector and the package case.
