An electronic module. The electronic module includes a chassis (10), a plurality of capacitors (36), a plurality of bus bars (30), and a heat sink (38). The chassis includes a first end (14) and a second end (16). The first end is opposite the second end. The capacitors are positioned within the chassis, and at least one of the capacitors is proximate the first end. The bus bars are positioned within the chassis proximate the second end. The heat sink is positioned between the capacitors and the bus bars. The capacitors, the heat sink and the bus bars are positioned such that when an airflow enters the chassis at the first end (14), a portion of the airflow sequentially comes in contact with the capacitors, the heat sink, and the bus bars before exiting at the second end.
