The design of tantalum capacitors is based on the structure of tantalum, which looks a lot like a sponge. Such a structure contains an anode, a cathode and a dielectric. The manufacturing process of this type of capacitor begins with compressing tantalum powder around a tantalum wire and sintering it at high temperature, to create the anode.
SMD capacitors are the most common type of tantalum capacitors. SMD tantalum capacitors are a close match to the standard MLCC case sizes, thanks to which MLCCs could be replaced with tantalum capacitors without the need to change the PCB footprint.
The tests and requirements to be met by aluminum and tantalum electrolytic capacitors for use in electronic equipment for approval as standardized types are set out in the following sectional specifications: Tantalum capacitors are the main use of the element tantalum. Tantalum ore is one of the conflict minerals.
The dielectric used in all tantalum electrolytic capacitors is tantalum pentoxide. Tantalum pentoxide compound possesses high-dielectric strength and a high-dielectric constant. As capacitors are being manufactured, a film of tantalum pentoxide is applied to their electrodes by means of an electrolytic process.
The original wet tantalum capacitors developed in the 1930s were axial capacitors, having a wound cell consisting of a tantalum anode and foil cathode separated by a paper stripe soaked with an electrolyte, mounted in a silver case and non-hermetic elastomer sealed.
SMD tantalum capacitors are a close match to the standard MLCC case sizes, thanks to which MLCCs could be replaced with tantalum capacitors without the need to change the PCB footprint. In the case of tantalum capacitors, not only length and width are indicated in terms of dimensions (as in MLCCs) but also height.
