Customer Change Notification​

KEMET Tantalum Part Number Standardization

Date:
October 1, 2011
ID Number (MMDDYY): CCN-10012011-CWF
Affected ProductsAll B45xx and Txxx Evora Surface Mount Tantalum products.
ChangeConsolidating B45 part numbers into the KEMET Core Txxx part numbering system. Automotive customers will need to include a customer specification: C-AUxx or Axxx to designate Automotive part numbers. AU=Auto, xx= 01-99, A=Auto, xxx=ESR level
Justification & BenefitsIn an effort to standardize all KEMET Tantalum part numbers, KEMET will cross all part numbers currently ordered using the Epcos B45xx part number to a KEMET core Txxx part number. Automotive part numbers will include the addition of a customer specification C-AUxx or Axxx to designate an automotive part number. This will insure proper control for change notifications.
Effective Date & IdentificationAll part number changes will be completed by April 1, 2012. Please see attachment showing the B45 numbering system as compared to the KEMET core numbering system. Please contact your local KEMET Sales Representative if you have any uncertainty on how to cross reference part numbers.
