Tantalum and Niobium capacitors belong to electrolytic capacitor types, and they are known for their high capacitance in small dimensions (high energy and power density), reliability and stability of its parameters. Traditionally, tantalums’ advantages over aluminum electrolytic capacitors have been found in terms of capacitance per volume, parameter stability over temperature, and longevity; tantalums

The basic idea of electrolytic capacitor types is to maximize the surface area of electrodes and thus increase their capacitance value and capacitance density. Fine pores and cavities created on the electrode (anode) surface are then covered by a dielectric – usually insulator/semiconducting metal oxides. The electrolyte in a liquid/wet, gel or solid form is used as a medium to contact the high surface from the second side and bring it by its electrical conductivity mechanisms to the second electrode (cathode).

The early identification of parts affected by an alert is important to avoid the use of that part in the design if an alternative is available. In the case the part has already been procured, it is important to know about the alert to see which solutions are available or the specific impact of the alert on our application.

Regarding this, we can include them as deviations from the requirements of the Generic Specification or in the absence of a clear one fully define them (including methods, success criteria) on our Detail Specification, in accordance to our PA Plan.

the datasheet is not always under strict configuration control, and the information included can be changed without notice or even be outdated. This is, the datasheet is always under manufacturer control. This also implies that some parameter information that may be critical for a specific customer application may not be shown in the datasheet if the manufacturer does not consider it typically important. Furthermore, it may happen that this parameter has not even been measured ever.
