KEMET Spice Software KEMET Spice SoftwareVersion 3.7.2xThe KEMET Spice program 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, film, 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, Windows based program, it can create files that can be imported into some commercial versions of SPICE software.
Users can Download KEMET Spice Software - Version 3.7.2x Setup or Update files. After the download is complete, double-click on it to install.
Setup / Installation File:
If this is the first version of KEMET Spice being loaded on the targeted computer, or if the previous version is lower than 3.5.3, then you must use the setup program (9034 kBytes) 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. |  | NOTE - Windows Vista users:
You must right-click on the downloaded setup file and choose "Run as administrator" to install. |

KEMET FIT Calculator KEMET FIT Calculator SoftwareVersion 3.1.0A 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.
