An alternating current power capacitor including one or more capacitor bodies (e.g., bobbins) having conductive and dielectric film windings, wherein edges of the conductive film windings define a plane forming at least one capacitor body contact surface, one or more electrodes having one or more electrode contact surfaces and a housing operative to apply compressive force that binds the capacitor body and electrode together so that to maintain uniform electrical and thermal conductive contact throughout a plane parallel to and between the electrode contact surface and capacitor body contact surface.
