The Modelithics CLR Model Library™ contains the industry's first and only substrate- and part value-scalable models for surface mount components. These reliable, measurement-based models will help you get the most from your RF/MW electronic design automation (EDA) software, reduce cycle time, and lower product development cost.

The Modelithics CLR library contains models for a variety of body-sizes and part values for capacitors, inductors, and resistors from most major vendors, including ATC, AVX, Coilcraft, Epcos, KOA Speer, Murata, Panasonic, Rohm, TDK, and Toko. New models are added continuously.

With the CLR Library you will add Modelithics' patent-pending Global Model™ technology to your EDA design tools suite. Each Global Model pertains to a given component vendor and body style and typically covers values over 2-3 decades (e.g., 1-1800pF). All equivalent circuit parameters, and therefore the parasitic effects, vary as a function of the nominal part value.

Modelithics Global Models also incorporate advanced features that enable full accounting of substrate-related effects. Each model is generated from multiple sets of S-parameter measurements, made with parts mounted in different PCB fixtures. The models are valid over a continuous range of substrate thickness and dielectric constant, bounded by the fixtures used for model development.

Along with S-parameter measurements, each model in the Modelithics CLR Library is based on precise Effective Series Resistance (ESR) measurements. The empirical data is used to generate a frequency-dependent expression for ESR that is incorporated into the models. Whether you're concerned about heat dissipation, part failure, or a tight loss budget, Modelithics models will help you design with confidence.

The models in the Modelithics CLR Library use a physically-motivated equivalent circuit topology. A much simpler "series L-C" type model can often fit a specific set of measured S-parameters. However, such a model can fail badly when used in a configuration that differs from that used for model extraction. Modelithics models are experimentally validated to ensure accuracy in all common mounting configurations.
