Abstract:
Methods and devices related to fabrication and utilization of multilayer capacitors presenting coaxially arranged electrode layers. The capacitors may be self-shielded against electromagnetic interference with neighboring components. The capacitors may have reduced losses from fringing effects when compared to conventional capacitors. The coaxial capacitors may be two-terminal multilayer ceramic capacitors (MLCC). The design of the capacitors may facilitate an improved relationship between the electric and magnetic fields generated by the capacitor within the dielectric in some embodiments. In some embodiments, the placement of the terminals may lead to a cancelation of mutual inductances between the electrodes. Terminations that facilitate the coupling of the capacitor to a circuit board, as well as methods for fabrication of the capacitors are also discussed.
