Abstract
Improved balance winding of electronic components including common-mode chokes and methods for using and manufacturing the same. In one embodiment, the common-mode choke includes a core and a pair of windings. The first winding and the second winding are alternatingly wound around the core with each respective winding being flipped at least once over the traverse direction of the winding barrel of the core. In one variant, the number of flips is dependent upon the core geometry, number of windings, and/or the specification limits on electrical balance. In another variant, the windings are first twisted and/or braided prior to being wound onto the winding barrel of the core.
