KEMET NetList Files - SIMPLIS/(SIMetrix)

SIMetrix/SIMPLIS simulation software (link to Simplis web site: http://www.simplistechnologies.com/)

Once you have downloaded the model files, you may install them in SIMetrix/SIMPLIS just like you would a MOSFET or Diode model. Just drag and drop the file icon (.ckt file extension) into the SIMetrix/SIMPLIS command shell window. Click the OK button on the resulting dialog box confirming that you want to install this model in the Model Library. You can then place the new capacitor on a schematic using the "Place | From Model Library | Capacitors" menu option.

These files (*.ckt) contain element values of a prescribed network, whose artwork may be seen in associated JPEG (*.jpg) or AutoCAD Symbol library files (*.slb). These files may be downloaded from the KEMET Spice web page.

Unique to these files is the second comment line defining the capacitor as polar:
*#ASSOC symbol=cap_polar_us category=Capacitors simulator=simetrix|simplis
or as non-polar::
*#ASSOC symbol=cap category=Capacitors simulator=simetrix|simplis

Here is a Notepad view of one of the film capacitor model/file:

This is a non-polar capacitor type of 10 nF capacitance rated at 100 VDC.

The MLCC files are collected in groups and compressed in Zip files. The 1st group was added with version 3.7.5 and it consists of the model for each element for a four capacitor array in an 0612 package (series "CA064"). The 2nd group “KEMET MLCC C0201-C0805” consists of the ceramic chips or part types including C0201, C0402, C0603, and C0805, while the 3rd group, "KEMET MLCC C1206-C1825", contains C1206, C1210, C1812, and C1825, and the 4th group "KEMET MLCC C2220-C2225" contains the C2220, and C2225. These include all dielectrics: C0G, X5R, X7R, X8L, X8R, Y5V, and Z5U, where applicable. The 5th group consists of recently released KPS series ("J-Type" leadframe with one or two chips), are X7R and contain C1210, C1812, and C2220 sizes. The 6th, and last, group contain the DSCC 0302x series capa citors as well as the CDR0 and CDR3 series.

These models were changed at the request of Simplis. The degrees symbol (°) is no longer allowed - omitted from file name. All spaces in the file names have been converted to underscore characters ("_"). For models representing multiple pieces, the normal designation is to place the multiplying number within brackets and adding that designation to the PN (e.g., C1206C105K5RAC [5] represented a model of five (5) of the 1 uF chips in parallel). For Simplis files, the PN will have an underscore, a small case "x", and the multiplying value (e.g., C1206C105K5RAV_x5 represents a model of five (5) of the 1 uF chips in parallel).

The KEMET Alum-Polymer AO SMD Capacitors are contained in the following ZIP file:

The tantalum commercial SMD capacitors, with MnO₂ cathode systems include the standard T491, T494 (lower ESR by test version), T495 (lower ESR by design), T496 (internally fused for fail-safe), T497 (high reliability), T498 (+150°C operation), T499 (+175°C operation), and T510 (ultra-low ESR by multiple anodes).

Military versions of the Tantalum-MnO₂ devices include T4x9 [T409 (CWR09), T419 (CWR19), T429 (CWR29)], T492 (CWR11), and T493 (COTS) capacitor types.

For lower ESR devices, a conductive-polymer is used in place of the MnO₂ cathode system, achieving ESRs down below 10 milliohms. These include types T520 (ESRs down to 4.5 milliohms, maximum temperature to 85°C), T525 (extended temperature range to +125°C), T521 (new higher voltage from 20Vdc to 35Vdc), T528 (facedown package with ESLs approaching 100pH, and higher ripple capability), and T530 (higher capacitance but ultra-low ESRs down to 3 milliohms, and temperature range to 125°C).

Most recently added is the surface-mount film capacitors. These are divided by dielectric types: PEN, PET, PPS, and Paper. The PEN are the polyethylene naphthalate with a temperature capability from -55°C to 150°C(125° is standard). These are characterized with dielectric constant of 3.0, minimum thickness of 1.4 um, typical dissipation factor of 0.4%, and a dielectric absorption rating of 1.2%. These include part types with series designations of GMC, GMW, and GPC, and the LDE sereis.

The PET are the polyester film capacitors with a temperature capability of -55°C to 125°C(100°C is standard). These are characterized with dielectric constant of 3.3, minimum thickness of 0.9 um, typical dissipation factor of 0.5%, and a dielectric absorption rating of 0.5%. These include part types with series designations of MMC for the surface mount capacitor and MDC, MDK, and MDS for the DIL surface mount packages.

The PPS are the polyethylene sulfide with a temperature capability from -55°C to 150°C(125° is standard). These are characterized with dielectric constant of 3.0, minimum thickness of 1.2 um, typical dissipation factor of 0.06%, and a dielectric absorption rating of 0.01%. These include part types with series designations of SPC, SMC, and SMW. The LDB series are stacked multilayer 1206, 1210, 1n2 1812 chip devices.

The metalized Paper types are limited to the single series: SMP253. These are high-voltage capacitors explicitly designed for class Y2 EMI filtering. The voltage rating for these capacitors is 250 VAC, whereas all other capacitor types have their voltage ratings expressed as VDC.

Following is from joint press release from KEMET and Simplis:

KEMET’S PRODUCT LIBRARY AND CAPACITOR MODELS ARE NOW AVAILABLE ON THE SIMETRIX/SIMPLIS SIMULATION TOOL

Greenville, South Carolina (February 17, 2009) – KEMET Corporation (KEME.OB), The Capacitance Company, announced that it has released its full line of capacitor models to the SIMetrix/SIMPLIS simulation software, which allows Signal Integrity, Power Integrity, and board design engineers to model the decoupling scheme of a printed circuit board using the SIMetrix/SIMPLIS simulation software. KEMET’s new low ESR and low ESL polymer products are specifically designed for the high speed processor board level decoupling applications.

Using the SIMetrix/SIMPLIS simulation tool, design engineers will have the ability to model the time-domain and frequency behavior of Aluminum, Film, Ceramic, and Tantalum SMD capacitors manufactured by KEMET. This new resource will make it easier for the products of tomorrow to be designed using KEMET capacitors. KEMET has modeling software, Spice, which is available on its website kemet.com. Spice is a freeware product that aids design engineers by analyzing the performance of capacitors.

“KEMET’s goal is to get our models to perform with the most accepted, demanding, and accurate simulation software tools and we believe that we accomplish this goal with tools created by SIMetrix/SIMPLIS,” stated John D. Prymak, Director Advanced Applications, KEMET Electronics Corp. “Our focus continues to be on partnering with design engineers and helping to find the right capacitance solutions to accomplish their project’s specific need,” continued Prymak.

“SIMPLIS is the industry leading simulation tool that assists designers in figuring out how many and what type of output capacitors they need to address their customer’s application requirements,” stated Tom Wilson, President, SIMPLIS Technologies, Inc. “By taking this need seriously, and providing such high quality simulation models for their capacitors, KEMET is providing designers with extremely helpful information that will allow them to optimize their designs for cost and performance,” continued Wilson.
