A. In response to customer feedback, TDK decided to provide a simplified global catalog number to assist world wide procurement efforts within the distribution channel. As a result, the last five digits were changed to indicate thickness, packaging and MLCC series detail. Catalog numbers ending with "/SOFT" and "(0.85)", or abruptly ending after capacitance tolerance, are not necessary with the new TDK catalog number. (see Figure 1)

Counterfeit components involve a great risk from unauthenticated parts being incorporated into customers' products. Many suppliers are sensitive about this problem because there are problems with qualities and reliability of counterfeit components. By the time users notice, a large amount of counterfeit components may have been already used.
