Design Guidelines for Preventing Flex Cracking Failures in Ceramic Capacitors
Surface mount multilayer ceramic capacitors (MLCCs) are one of the most common components found on modern circuit card assemblies. Introduced in 1977, they are well known for their reliability and have been rapidly accepted by the electronics industry. The reliability of a nominal MLCC is extremely high, with expected operating lifetimes in the decades, if not hundreds of years. However, to att...
متن کاملParasitic Inductance of Multilayer Ceramic Capacitors
The parasitic inductance of multilayer ceramic capacitors (MLCCs) is becoming more important in the decoupling of high speed digital systems. There exists conflicting data and statements on the parasitic inductance of the MLCC. This work shows the measurement techniques of the inductance parameters, focusing mainly on the fixturing needed to accurately measure the chips. The effects of various ...
