JTIsoft® is comprised of two advanced design simulation software, MLCsoft® and MLIsoft®. It provides complete S-Parameter and SPICE modeling data on Johanson's line of RF multilayer ceramic capacitors and inductors over the frequency range of 1 MHz to 20 GHz. In MLCsoft®, the intuitive interface allows the user to select one of six MLCC sizes plus other part variables and displays the complete part number for accuracy when ordering. Ten electrical parameters including SRF, PRF1, PRF2, ESR, Q, and Ceff are displayed and update dynamically as chip size, capacitance value, and frequency are changed. In MLIsoft®, the user can select one of three MLCI sizes plus other part variables and display the complete part number for accuracy when ordering. Electrical parameters such as Rdc, Idc, SRF, Leff and Q are displayed and updated dynamically as chip size, inductance value and frequency are varied. Both MLCsoft® and MLIsoft® provide highly detailed graphical plots of device performance data in two basic formats over a user specified frequency range. The chart displays are instantly updated as the user makes capacitance or frequency changes. Smith chart displays of both impedance and S11/S22 are available as point plots, line plots, and line-point plots. Traditional X-Y graphs are available for parameters of S21 and S11 in the form of phase and magnitude, Impedance magnitude, Q, ESR , effective capacitance, and inductance. Display formats include Standard, Log Y, and Log/Log. There is also an option to display two parameters simultaneously.
