Electromagnetic wave absorption materials

For electromagnetic interference and asymmetric digital subscriber line, both transformers and splitter applications, new Mn–Zn ferrites are required with high impedance, stable frequency behaviour of the permeability, long reach for distortion-less digital signal transmission and high saturation, respectively. The new EPCOS materials T66, N45 and T38 improved show considerable improvements and are very well suited for these applications. This paper describes the applications and principles of the new designs T66, N45 and T38 improved.
