KEMET Spice Software - Version 3.8.3
The 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), film, tantalum, polymer, and aluminum polymer capacitor types. Each capacitor type behaves differently to the conditions (temperature, bias) 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. The catalogs may list capacitance, DF, ESR, and ripple current - but these are stated at specified temperature, bias, and frequencies. The program is intended to view the behavior of these devices to any conditions not covered in the catalog .
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 (9638 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. A "Freeware" declaration is in PDF format, adjacent to the setup download program. If you have a version of KEMET Spice of 3.5.3 or later, you can use the Update program (6686 Kbytes) as the system files were already loaded and not changed since version 3.5.3. |  | NOTE - Windows Vista users:
You must right-click on the downloaded setup file and choose “Run as administrator” to install. |

KEMET Spice Freeware Designation
28-Jan 2011 Rev 3.8.3
- When loading KPS of size 1210, 1825, or 2220, all sizes were being loaded, now only shows selected size.
- In looking for ceramic styles, beginning with “C” is now looking for “C4A” in preparation for power film of “C4A” prefix.
- When creating Cadence files, command button was retaining previous EDA model type, now shows “GO – Create Cadence Models”.
28-Jan 2011 Rev 3.8.2
- When creating Cadence files for a single piece during model-review form, DCM file was not being created– fixed.
17-Jan 2011 Rev 3.8.1
- When changing capacitance during parameter review, program was reverting to original capacitance – fixed.
15-Jan 2011 Rev 3.8.0
- Revisions will now be released three times per year (April-August-December), and each 4-month release will increment 2nd digit of revision numeration.
- Added SMD Film LDB capacitors (35), added CDR0 and CDR3 military part types to ceramic selections, added DSCC 0302x part types to ceramic selection.
- Corrected problem created by viewing Temperature Rise vs. Cumulative Ripple Currents, and then viewing Time based plots (dv/dt or Cap/dt) with Time Scale (X-Axis) problems
4-Oct 2010 Rev 3.7.52
- Ceramic not C0G or Z5U was not indicating over-voltage in Temperature Rise vs. Cumulative Ripple Currents Plot table with red backgrounds for specific currents - fixed.
- Table of mouse controlled Ripple Currents at Multiple Frequencies was not always cleared and hidden when switching to frequency based plots - fixed.
- Problems with calculated Leakage Resistance in truncating created problems with local formatting of string interpretations of numbers and problems with comma and decimal – problem eliminated.
18-Sep 2010 Rev 3.7.51
- Eliminated Temperature Rise vs. Cumulative Ripple Currents error after twice ignoring frequency range being too small, causing program to crash (division by zero).
17-Sep 2010 Rev 3.7.5
- Added Plot of Temperature Rise versus Combined, Multiple Frequencies/Currents
- Requested by Power Films for Fourier Analysis of Complex AC noise on filters.
- Allow up to 10 frequency/current entries and plots to show combined power-heating effects.
- Corrected Simplis/Simplex models :
- Removed spaces, and brackets, replacing with underscore (“_”); removed degrees symbol.
- Removed brackets in multiple piece designation from “[#]” to “_x#” as suffix to file name, prior to file type designation.
- “T520V337M2R5ATE4R5[10] 25°C 1.5 Vdc 300kHz.CKT” becomes “T520V337M2R5ATE4R5_x10_25C_1.5Vdc_300kHz.CKT”
- For MLCCs
- Corrected self-resonance calculations in Touchstone file generations (interpolation was wrong).
- Impacted low capacitance MLCC chips (<100 pF)
- Impacted Cadence models and Touchstone if self-resonance frequency point requested (ESR error ~ 0.6%).
- NetList models and all variations (Cadence, Mentor, etc.) calculated leakage resistance was lower than it should have been - fixed.
- Corrected choose type entry of part numbers - holds design IDs.
- Changed Ripple Current printouts so area colors are light enough to not mask grid lines and plot lines.
- Combine impedance pull-down menu function now works, along with <Ctrl><C> which was working.
- Corrected error in creating Shunt S-Parameter file from model review (was creating NetList file).
- Temperature correcting capacitance in C0G by -20PPM/°C.
- Changed program default “Start Frequency” from 1 kHz to 100 Hz for Film capacitors.
- Added KPS Series for Stacked Ceramic Chips (+181), C0G Hi Voltage now at 860 Part Types
- In reviewing 330 parts from the T495 style, 40 had corrections to their seed values (7/7/10), and in reviewing 352 from T491 styles, 91 had seed value corrections (7/2/10). All of the corrections were because of DF at 120 Hz.
Program Manual
This software has many capabilities that increase with each release and every attempt was made to detail the software and reveal its capabilities in this illustrated manual. It contains instructions on manipulating the temperature, voltages and frequency ranges.

Part List.XLS
Here is the Excel spreadsheet of part numbers. 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:
Download KEMET "PartList.XLS"
The piece count in this spreadsheet involves 545 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
KEMET FIT Calculator Software
Version 3.5.1
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(7, Vista, 95, 98, 2000 and XP) and NT. Please refer to the program for a revision history from previous versions.
Download KEMET FIT Software - Version 3.5.1 Once you have downloaded the application to your system, click on it to install it.
Add this file to update from previous versions without the need to have administrative rights (no dll or ocx files are copied to the system directory).
