AVX Introduces Capacitor Simulation Software

AVX Corp. has released an updated version of its SpiTanIII tantalum and niobium oxide (Oxicap) capacitor simulation software, which helps electronic design engineers model and build stable, robust and reliable designs. Featuring an expanded library of more than 3,000 part numbers and a new two-capacitor comparison function, SpiTanIII V2.0 allows engineers to access the all of the basic characteristics and parameters for AVX’s standard, polymer, wet, and conformally coated tantalum capacitors, including the new TCM series tantalum polymer multianode chip capacitors and the recently acquired F-series capacitors, in addition to its niobium oxide (Oxicap) capacitors.

“Updated on an annual basis to provide electronic design engineers with the most accurate technical information about and the most comprehensive simulation capabilities for tantalum and niobium oxide capacitors, the latest version of our SpiTanIII software features a broadly expanded library of part numbers; several new features, including our new two-capacitor comparison tool; and increased user friendliness, such as the new button specifically dedicated to generating S-parameters,” said Tomas Zednicek, Ph.D, technical marketing manager at AVX.

Accessible characteristics in the latest version of the SpiTanIII software include: capacitance, impedance, equivalent series resistance (ESR), dissipation factor (DF), ripple current, ripple voltage, and leakage current (DCL). Utilizing user input values for ambient temperature and, when evaluating DCL, derating levels, the program can accurately calculate, model, and compare capacitor performance simulations that reflect each designers’ unique application parameters, allowing design engineers to evaluate how changes in temperature affect frequency characteristics. New features accessible by a single, dedicated button also enable users to generate S-parameters, which are useful for designing circuits that require high frequency accuracy. Additionally, all graphs created in SpiTanIII V2.0 may be exported as image files or a list of data values viewable using spreadsheet software, such as Microsoft Excel, for further evaluation.

SpiTanIII V2.0 is available at www.avx.com. To download the executable file, hover over the “Spice Models/Software” button in the vertical, left-aligned menu on the AVX homepage and then click on “SpiTan III 2 (Tantalum and Niobium Oxide Capacitors)” in the resulting drop-down menu.
