Würth Elektronik eiSos and Modelithics are presenting the results of their cooperation project: with immediate effect, Microwave Global Models products are available for three product families of SMT high-frequency inductors.

HF developers now have the opportunity to test the 0402 and 0603 designs of the WE-MK, WE-KI, and WE-TCI coil families in simulations.

The Modelithics libraries are available for ADS (Advanced Design System) and Genesys and also for AWR Microwave Office.

The WE-KI, WE-MK, and WE-TCI series of coils in the 0402 and 0603 designs cover inductance values from 1 to 1,000nH and have been characterised by Modelithics up to 30GHz. Thanks to the substrate scalability, these models can be used on a broad range of substrates. The series resistance and natural frequency have been precisely measured and have been incorporated into the model.

Models validated by measurements
Larry Dunleavy, President and CEO of Modelithics, said: “With Würth Elektronik we’re welcoming one of the leading European suppliers of passive components into our Modelithics Vendor Partner Program. The cooperation between our two companies opens the way for the development and offer of high-quality simulation models of the inductances made by Würth Elektronik. Developers in the high-frequency area will profit from this.“

“We’re delighted that we’re now able to offer high-precision simulation models validated by measurements for the WE-MK, WE-KI, and WE-TCI product series. These models make it easier for our customers to design their products and drastically shorten the development times," said Hela Ben Htira, Product Manager at Würth Elektronik eiSos.
