High Temperature Tantalum-MnO2 Capacitors: >200° C

For years, the Tantalum SMD MnO2 Capacitor, in its solid-state structure, was typically rated with a maximum temperature rating of 125°C. The introduction of advanced technology, some time ago, allowed increasing the maximum working temperature to 150°C, 175°C and 200 °C respectively. Now, with the introduction of more advanced materials, such as carbon and silver, and the implementation of state of the art processes such as Nickel platting, optimizing chemical impurity (F-Tech) and a non-destructive testing technique (SBDS), the temperature range capability of Tantalum SMD MnO2 Capacitor can be extended to more than 200°C. This paper will provide the current results obtained during the development process of new T501 series (>200°C), parametric and statistical data are shown for each tests performed. A discussion of the advantages related to the use of these new technologies is included. The path forward to get a final qualification for this product is also discussed. Potential application areas for this...
