KEMET Spice Software
Version 3.9.66

KEMET Spice Software is freeware intended to aid design engineers in analyzing the performance of these capacitors over frequency, temperature, ripple, and DC bias conditions. The capacitor types include ceramic (MLCC), tantalum, polymer, and aluminum polymer capacitor types. Each capacitor type behaves differently to the conditions of the circuit, some showing no changes to moderate changes, while others showing very large changes to these conditions. Although it is a stand-alone, As a Windows based program, it is able to create files that can be imported into some commercial versions of SPICE software. Setup / Installation File: To set up the latest version of KEMET Spice on the targeted computer, you must use the setup program (20.5 MB) to load the required *.DLL and *.OCX files into the System32 directory. Because it will write these files to the System32 directory and write to the registry, you will need administrative rights to load the program successfully. The "Update" options are no longer offered as the setup file will uninstall the previous version of KEMET Spice before installing the latest version. A "Freeware" declaration is in PDF format, adjacent to the setup download program. The instructional manual ("Instructions for KEMET Spice 3.9.6x.pdf") details the operation of this software.		NOTE - Windows Vista users: You must right-click on the downloaded setup file and choose "Run as administrator" to install.

It is a collection of part numbers used to guide the creation of models exported from KEMET Spice for the purpose of importing these models into the various commercial design programs. The intended location for this file is in the "CKTs" subdirectory of the directory where KEMET Sp.EXE is loaded, (i.e., "C:\Program Files\KEMET_Spice\CKTs\"). These represent mostly decade values of many styles, dielectrics, voltage ratings, and sizes; but it is intended to filled with only those part numbers that are used by each customer:

The piece count in this spreadsheet involves 667 part types, with some creating a single model representing multiple chips. There are some part numbers which will not create models as these were included to demonstrate incorrect part numbers or restrictions if part number is not matched in KEMET Spice.

The models referenced in the "Models" file listings are included in the following "Circuit Drawings.zip" compressed file as JPEG presentations of the referenced circuits.

KEMET FIT Calculator Software
Version 3.5.31

A method of predicting reliability based on stress and environmental factors has been available for many capacitor types. The calculations found in MIL-HDBK-217 (revision F) allow the ambient temperature, application bias, and environmental factors to create multipliers of established failure rates for many military part types. Based on the monitored reliability of the non-military, commercial part types, these same multipliers can be used to define a projected application failure rate. The failure rates are listed as “FIT” (failures in time), and “MTBF” (mean time before failure).

This calculator software is intended to follow the calculations spelled out in this handbook for the specific part types that KEMET manufactures: ceramic multilayer capacitors, solid-tantalum capacitors, and the latest, the solid-aluminum capacitors. Just enter the capacitance, the voltage rating, and the part type, and the calculations are immediate. Manipulate the temperature and the voltage to see the impacts instantly.

Download the FIT Calculator Software manual in PDF format to see the impact of each element of the program, or activate the Help screen to search for additional information on the calculations and all of the elements.

This software is applicable for Windows (95, 98, 2000 and XP) and NT. Please refer to the program for a revision history from previous versions.

KEMET Flex Mitigation Solutions

Flexible Termination technology utilized in several series of KEMET surface mount multilayer ceramic chip capacitors (MLCCs) was developed to address flex cracks, the industry's primary failure mode for MLCCs. Flexible termination directs circuit board stress away from the ceramic body and into the termination area, reducing the risk of mechanical damage to the component that can result in low IR and short circuit failures.
