Abstract
A common mode choke may include a generally rectangular body including bottom and top ferrite portions, at least one pair of laterally spaced apart interior conductors between the bottom and top ferrite portions and extending between the first and second ends of the generally rectangular body, and a dielectric material layer between the bottom and top ferrite portions. Moreover, the dielectric material layer may also extend laterally between the at least one pair of interior conductors and may also at least partially encapsulate the at least one pair of interior conductors at portions thereof opposite at least one of the bottom and top ferrite portions. The choke may also include end conductors on the opposite ends of the generally rectangular body and connected to the interior conductors. A compact footprint is provided for the common mode choke while maintaining a high level of electrical performance.
