A manufacturer of advanced passive components and interconnect equipment has made enhancements to its SpiTan software for simulation and modeling of tantalum capacitors. Features in SpiTan III include the effects of temperature and voltage on DCL leakage current, equivalent circuits of capacitors with parameter values, and more than 80 new released codes. The company has also developed a library of models of its tantalum capacitors. Five of the most common case sizes (A, B, C, D, E) are now available in STEP (Standard for the Exchange of Product Model Data) format. In addition, AVX has updated its SelectCap capacitor selection program to include all parts released in 2009. All programs are available from http://www.avx.com.
