A three-phase boost-buck PFC converter including three independent single-phase boost-buck PFC circuits respectively is provided, which are capable of performing PFC on each phase of the three-phase power. This cable is a specific form of a more general cable which utilizes a central spline which is designed to separate all but one pair of component cables to provide for material savings in cable construction which still sufficiently reducing cross-talk to meet data cable design specifications. Size of the first opening portion is of the same level as a contact hole of a component and cannot be recognized by an image recognition apparatus.
