AI Customer ServiceSurface mount technology tantalum capacitors are increasingly being used in new circuit designs because of their volumetric efficiency, basic reliability and process compatibility. Additionally, they are replacing aluminum electrolytics, which use a wet electrolyte.
Areas of interest are highlighted. The electrical characteristics of a tantalum capacitor are determined by its structure, for example the ESR of a tantalum capacitor is very dependent on the tantalum pentoxide dielectric at low frequencies and on the internal manganese dioxide at higher frequencies.
Tantalum capacitors are manufactured from a powder of pure tantalum metal. A typical particle size for a high voltage powder would be 10 μm. By carefully choosing which powder is used to produce each capacitance/voltage code the surface area can be controlled. Powders with large particle size are used to produce high voltage capacitors.
It is also of interest that because of the solid nature of the tantalum capacitor’s construction, there is no known wear out mechanism in tantalum capacitors. This paper has been written to provide the user of tantalum capacitors with an idea of the effect of design criteria on the capacitor and the methods used in their production.
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.
In solid tantalum electrolytic capacitors the heat generated by the ripple current influences the reliability of the capacitors. Exceeding the limit tends to result in catastrophic failures with shorts and burning components.
