An apparatus is disclosed to include: a conductor structure (such as a
busbar) comprising a first
electrical connection and a second
electrical connection; a first
capacitor pair including a first
capacitor and a second
capacitor mounted directly opposite each other on opposite sides of the conductor structure, wherein the first and second capacitors each have a first
electrical connector and a second
electrical connector having a first electrical
capacitance therebetween, and wherein the first and second capacitors each have a first side and a second side opposite the first side; a first connection arrangement connecting the first
electrical connector of the first capacitor and the first electrical connector of the second capacitor to the first
electrical connection of the conductor structure; and a second connection arrangement connecting the second electrical connector of the first capacitor and the second electrical connector of the second capacitor to the second electrical connection of the conductor structure. The first electrical connectors on the first side of the respective capacitors are aligned on the respective sides of the conductor structure and the second electrical connectors on the first side of the respective capacitors are aligned on the respective sides of the conductor structure.
