Ansoft, SAMSUNG Unveil Multilayer Ceramic Chip Capacitor Models

Ansoft Corporation (NASDAQ:ANST) and SAMSUNG (Samsung Electro-Mechanics Co. Ltd.) announced the release of a new model library of SAMSUNG’s high-density, miniaturized surface-mount Multilayer Ceramic Chip Capacitors (MLCC). MLCCs are used for decoupling and temperature compensation in applications where PC board space is limited. They are ideal for new wireless and portable product designs, including notebook computers, mobile phones, PDAs, camcorders, VCRs, telecommunications and test equipment. The new MLCC library allows engineers using Nexxim(R) and Ansoft Designer(R) to simulate advanced PCB and hybrid IC designs.

“The rapid advancement of mobile communications and small electronics products is driving demand for parts with ever-higher precision. For example, the slimmer mobile phones currently leading the market are forcing component manufacturers to develop ultra-small parts with very high capacity,” said Kangheon Hur, vice president of SAMSUNG. “We are pleased to team with Ansoft to address customer needs for accurate simulation and manufacturing data so that these high-performance components can be readily incorporated into the next generation of products.”

The MLCC components provide outstanding high-frequency properties, high reliability, low cost and ultra-small size. The new library contains over 400 capacitor models ranging in capacitance values from .5 pf to 47 uf for use with operating voltages up to 50 V depending on chip size (available chip sizes range from 0201 to 1206). Each component model utilizes S-parameter data from actual device characterization to provide excellent accuracy of the capacitor’s electrical response within a Nexxim simulation. Nexxim is able to use the frequency-domain models provided by the S-parameters in both frequency- and time-domain analyses.

The library is available from SAMSUNG’s Web site and is easy to download (under Products/Capacitors-MLCC/Technical Tool) and configure for use within Nexxim and Ansoft Designer. This site provides Ansoft customers with the ability to search for components by name, performance data or other specification. SAMSUNG will maintain model support and upgrades, while Ansoft will address all customer support for Nexxim and Ansoft Designer.
