Equivalent series resistance-the fourth parameter for tantalum capacitors

The author outlines the reasons behind the interest in ESR (equivalent series resistance) of surface mount devices and details the processing steps which affect the ESR of a tantalum capacitor. It is noted that the operating frequencies of products which use tantalum surface mount capacitors are continually increasing. These higher frequencies have resulted in ESR becoming a specified parameter in numerous user drawings, industry standards, and military specifications for tantalum chips.<
