KEMET NetList Files - Sigrity

These models are subcircuit model files, collected in groups and compressed in Zip files. Here is a Notepad® view of one of the files:

The 1st group consists of the ceramic capacitors "Sigrity MLCC Array CA0x SMD.zip" of four capacitor arrays in an 0612 package. The next groups consists of the ceramic capacitors of 0402, 0603, 0805, 1206, 1210, 1812, 1825, 2220, and 2225 sized chip capacitors, each in their own compressed file. Next come the KPS series of chip capacitors with leadframes mounted (sizes 1812 through 2220). The Mil-C-Prf or CDR0 and CDR3 series are in the "MIL CDR SMD" collections and the DSCC 03028 and 03029 series are in the "MIL DSCC 0302x" collection.

The aluminum-polymer capacitor (AO) files are contained in a separate zip file.

The tantalum SMD capacitors, with MnO2 cathode systems include the T489 (lower Leakage),T491 (standard commercial), T494 (lower ESR by test version), T495 (lower ESR by design), T496 (internally fused for fail-safe), T497 (high reliability), T498 (+150°C "HiTemp" operation), T499 (+175°C "HiTemp" operation), and T510 (ultra-low ESR by multiple anodes).

Military part types include T409 (CWR09), T419 (CWR19), T429 (CWR29), T492 (CWR11), and T493 (COTS).

Tantalum with conductive-polymers (lower ESR and non-ignition failure) include the capacitor types T520 (polymer rated to +105°C), T521 (high voltage polymers >16 Vdc), T522 (lower Leakage), T525 (rated to +125°C), T528 (facedown for low ESL and higher ripple current), and the T530 (ultra-low ESR using multiple anodes and conductive polymer rated 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 (boxed SMD), GMW (naked film), and GPC (boxed SMD). A more conventional SMD package can be found in the LDE series (1206 through 6054).

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 ("L" Lead with standoff), MDK (Insertion Lead), and MDS ("L" Lead with minimized standoff) 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 (boxed SMD), SMC (boxed SMD), and SMW (naked film). A more conventional SMD package can be found in the LDB series (1206 through 1812).

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.
