摘要：
Since ceramic capacitors are good for high frequency smoothing while risk of transient & oscillation, tantalum capacitors are good for compromise, relatively easy for reliable DC/DC design. In order to resolve transient failures of tantalum capacitances, discussion on multilayer ceramic capacitors (MLCC) replacement for tantalum capacitors was presented in this paper. Firstly, performance comparison of MLCC and tantalum capacitances was studied. Then MLCC mechanical robustness against cracking was analyzed. In order to achieve the mechanical robustness against cracking, some installation process was proposed. The results indicated that MLCC metal stent can provide a high-capacity, which solve the stress defect caused in manufacture process. Also it can meet the high reliability requirement.
