Zusammenfassung:Methods and structures are provided for implementing feed-through and domain isolation using ferrite and containment barriers. A vertical isolator is provided between a first domain and a second domain on a printed circuit board with signals passing between the first domain and the second domain. The vertical isolator is placed over a domain separation gap between the first and second domains in the printed circuit board, the vertical isolator having a vertical isolation barrier between a first vertical plate coupled to the first domain and a second vertical plate coupled to the second domain. The vertical isolation barrier is formed of a unitary ferrite block or a non-conductive magnetic absorber material. A plurality of capacitance feed-through plates and a dielectric material are provided within the vertical isolator.
