​​​KEMET NetList Files - Ansoft

The files are collected in groups and compressed in Zip files. The 1st groups consists of the ceramic or MLCC part types including C0201, C0402, C0603, and C0805, in “Ceramic MLC C0201-C0805 SMD Ansoft CKT.zip”; and C1206, C1210, C1812, C1825, C2220, and C2225 in the group "Ceramic SMD C1206-C2225"; and capacitor arrays (the four capacitor array CA04 replacing the previously listed 0612 and 1632 chips) in the group "Ceramic MLC CA0 Arrays SMD Ansoft CKT.zip". These include all dielectrics: C0G, X5R, X7R, Y5V, and Z5U, where applicable. The KPS series (one or two chip capacitors with leadframe are in the "Ceramic MLC KPS 1210-2220 SMD Ansoft CKT.zip" and these are all X7R dielectrics. The DSCC 03028 and 03029 series, as well as the Military CDR0 and CDRR series are contained in "Ceramic MLC DSCC CDR SMD Ansoft CKT.zip".

The aluminum polymer capacitor (A700) files are contained in a separate zip file.

The tantalum commercial SMD capacitors, with MnO2 cathode systems include the T489 (lower Leakage), T491 (standard commercial), T494 (lower ESR by tighter screening), 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 T409 (CWR09), T419 (CWR19), T429 (CWR29), T492 (CWR11), and T493 (COTS) capacitor types.

Tantalum with conductive-polymers (for lower ESR and non-ignition failures) 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 are the COTS versions of the tantalum polymer capacitors. The T540 represents a COTS version of the T525, and the T541 represents the COTS version of the T530 (multiple anodes). COTS requires control over design plus additional screening tests.

Next are 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 PEN dielectric part types with series designations of GMC, GMW, and GPC. The PEN surface mount chips in standard SMD packages from 1206 through 2225 are contained within the LDE series of capacitors.

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 capacitors, 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 represents a more conventional SMD in packages 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 (7 CKT files).
