Enabling design engineers to accurately simulate the performance of the company’s Ultra-Low ESR series multilayer ceramic capacitors (MLCCs) in circuit simulations, Modelithics adds Syfer’s Ultra-Low ESR range to their component modelling library. They are the first addition to Syfer’s Modelithics Component Model Library.

The Ultra-low ESR range offers a very stable, High Q material system that provides excellent, low loss performance in systems below 3GHz. Available with various termination options including FlexiCap, this range of high frequency capacitors is suitable for many applications where economical, high performance is required. Additionally, they are now fully integrated with a variety of software applications including Agilent ADS, Agilent Genesys, and AWR Microwave Office.

Modelithics Global Models reliably track how each component's performance will change with substrate characteristics and automatically scale all substrate-sensitive parasitics with nominal part value, enabling a single model to generate accurate simulations of a complete component family.

Steve Hopwood, Senior Applications Engineer, Syfer, commented: “Simulation-ready models like Modelithics Models can save designers considerable amounts of time and money on new designs. For many applications where economical, high performance is required these new Modelithics Models for our Ultra-Low ESR capacitors will be beneficial to RF and microwave designers. In particular this range of high frequency capacitors is ideal for use in RF power amplifier assemblies, mobile communications, satellite, GPS, automotive, matching networks, and wireless LAN applications.”

“We are very pleased to welcome Syfer as a new Strategic Modelithics Vendor Partner and we look forward to helping designers get great design results with these models. The Syfer Ultra-Low ESR capacitor range utilises a very stable High Q ceramic material to give excellent low loss performance in systems over a wide temperature range from -55 to +125°C. To offer increased reliability with superior mechanical performance Syfer’s FlexiCap termination system option is available along with various other termination options. RoHS-compliant finishes are standard. Parts are available taped and reeled as well as bulk packaged," comments Larry Dunleavy, President and CEO, Modelithics.
