An electrical connector includes a housing having a plug cavity configured to receive a modular plug therein. A terminal assembly is coupled to the housing. The terminal assembly has a plurality of terminals configured to engage corresponding terminals of the modular plug. The electronic connector includes a magnetic assembly that has a circuit board. The terminals are terminated to the circuit board. The magnetic assembly has magnetic circuits coupled to the circuit board. Each magnetic circuit has a ferrous portion and conductors circumferentially wrapped around the ferrous portion. At least one of the magnetic circuits is coated with a coating material that includes a matrix and filler. The filler can have a higher or lower dielectric constant than the matrix. The dielectric characteristics of the nano-composite can be tuned by varying the concentrations of the filler and matrix material. This tunable nano-composite can serve as an additional design knob for better impedance matching for the magnetic connectors over a wide frequency range.
