Chip tantalum capacitors have characteristics such as long service life,high-temperature resisitance,large capacity and they have a wide range of applications.However,many problems may also occur in actual use.This paper studies the structure of the chip tantalum capacitor,and briefly introduces the failure mode and and main failure mechanisms.Aiming at four typical cases of chip tantalum capacitor,the failure reason and mechanism analysis is carried out according to the component failure analysis process.Finally,it summarizes several factors that affects the reliability of chip tantalum capacitors,provides a reference for relevant personnel to use tantalum capacitors.
