Abstract:
A common mode filter coupled to a protection device. In accordance with an embodiment, the common mode filter has first and second coils, each coil having a spiral shape, a central region, an exterior region, a first terminal, and a second terminal, wherein the first terminal of the first coil is formed in a first portion of the central region, the first terminal of the second coil is formed in a second portion of the central region, and wherein the central region is laterally bounded by the first and second coils and the exterior region is not surrounded by the first and second coils. The protection device has a first terminal coupled to the first terminal of the first coil and a second terminal coupled to the first terminal of the second coil.
