AVX Updates Libraries

GREENVILLE, S.C. — AVX Corporation has expanded the capabilities of its SpiTanIII software to enable designers to view all basic characteristics and parameters for tantalum and Oxicap(R) (niobium oxide) capacitors. AVX has also introduced a new S-parameter library in v1.1, which includes s2p files.

SpiTanIII v1.1 software enables designers to choose a desired component by part number or by categories including capacitance, rated voltage, case size or series. For selected capacitors, all basic parameters, such as the frequency characteristics of capacitance, ESR, impedance, DF and ripple current and ripple voltage ratings are displayed. Furthermore, leakage current DCL vs. time progress can be studied and an equivalent circuit diagram with values of all elements can be displayed. Graphs can be exported for further evaluation.

This latest version includes part numbers of various SMD chip capacitor series introduced in 2010 and for the first time, high-reliability and performance wet tantalum axial capacitors are featured in the software database. New features include maximal ESR curves vs. frequency and temperature, maximal leakage current DCL curve vs. time and the S-parameter s2p files generator. The software can be downloaded from:

The S-parameter s2p Library v1.1 files are useful for high frequency application circuit simulation. The standard s2p format library for tantalum and niobium oxide capacitors are generated for all part numbers with the latest SpiTanIII v1.1 database. More than 6400 files are included, where two files are linked to each part, one for series connection in two-port networks and the other for shunt connection. The updated calculus allows a pair of s2p files – *ser.s2p and *shu.s2p – to be generated separately for each selected capacitor from SpiTanIII v1.1 simply by using a single dedicated button.

The library is available at:
