Waldenburg, Germany. As part of their Microwave Global Models cooperative effort, Würth Elektronik eiSos and Modelithics are making available models for two more Würth Elektronik eiSos product series. Consequently, developers can simulate the high-frequency response of WE-KI-HC high-current ceramic inductors and the WE-CAIR air coils. The models offer advanced functions to improve accuracy and to accelerate HF simulations. They support scalable parameters for substrate properties and incorporate pad dimensions and inductance values. The models are compatible with numerous EDA tuning and optimization tools.
The new Modelithics Microwave Global Models are available for WE-KI-HC Series 0402 and 0603 devices, which cover the inductance values from 1.0 to 51 nH and 1.8 to 390 nH. Moreover, five WE-CAIR air coil series are modeled: 1322, 1340, 3136, 3168, and 4248, which together cover inductance values from 1.65 nH to 120 nH. All models are validated up to 30 GHz. The models were developed to provide RF developers with an analysis function and accurate simulations in the first run.
The inductor models are created for seamless integration in common design tools like Keysight ADS and Genesys, NI AWR Design Environment, and ANSYS HFSS and Sonnet Suites. Würth Elektronik eiSos, as a Modelithics vendor partner, sponsors free 90-day tests of the component models, which are available from Modelithics at www.modelithics.com/MVP/Wurth. More information on WE-KI-HC is available here and on WE-CAIR here. The components are available at any time in any quantities from stock; free samples can be requested.
