In summary, TDK now provides design tools for various electronic components to support optimal component selection. In the TVCL tool, TDK provides a multi-purpose simulation model for S-parameters and equivalent circuit models, Netlists, and simulation models for commercially available simulators. For analyzing component characteristics, TDK has a tool called SEAT, which can analyze TDK component characteristics without needing commercially available simulators. In addition, TDK also provides CCV, which allows the user to confirm frequency characteristics online.
