Abstract:
Tantalum capacitors have been the preferred capacitor technology in long lifetime electronic devices thanks to the stability of its electric parameters and high reliability. However, long time application of elevated temperature and high electric field can result in capacitor leakage current increase in time. In this paper the effect of ions drift and diffusion at different temperatures on DCL degradation is analysed.
