1. A power module comprising:
a substrate having a top surface with a first trace and a second trace;
a first plurality of vertical power devices and a second plurality of vertical power devices that are electrically coupled to form part of a power circuit;
a first terminal assembly comprising a first elongated bar, at least two first terminal contacts, and at least two first terminal legs that respectively extend between different points of the first elongated bar and the at least two first terminal contacts;
a second terminal assembly comprising a second elongated bar, at least two second terminal contacts, and at least two second terminal legs that respectively extend between different points of the second elongated bar and the at least two second terminal contacts; and
a housing that includes four sides between a top surface and a bottom surface wherein the housing encapsulates at least a portion of the first terminal assembly and the second terminal assembly, such that:
first and second ones of the at least two first terminal legs extend out of first and second sides of the housing and fold such that the at least two first terminal contacts extend over and are parallel to the bottom surface of the housing; and
each of the at least two second terminal legs extends out of a third side of the housing and turns, wherein the at least two second terminal contacts form an angle between 75 and 105 degrees with the bottom surface of the housing, wherein the third side is between the first side and a second side of the housing.
