摘要
基于199D系列钽电容器是一种引线式固体坦电解电容器,在工作中主要起到滤波的作用,广泛应用于航天领域中。为保障199D系列钽电容器的可靠使用,对该系列钽电容器的结构特点和使用失效情况进行分析,梳理和总结出典型的缺陷模式。根据得到的缺陷模式,设计新的检测方法进行试验,最终验证新的检测方法更能有效检测出199D系列钽电容器的潜在缺陷。
199D series tantalum capacitor is a lead-type solid tank electrolytic capacitor,which mainly plays the role of filtering in the work,and is widely used in the aerospace field.In order to ensure the reliable use of 199D series tantalum capacitors,this article analyzes the structural characteristics and use failures of this series of tantalum capacitors,combs and summarizes the typical defect modes.According to the obtained defect mode,a new detection method is designed to test,and finally the new detection method is more effective in detecting the potential defects of the 199D series tantalum capacitors.
