Tantalum Capacitors offer many advantages over other types of capacitor. This has meant that their use has risen considerably over the years, and now they are widely used in all forms of electronics equipment. The advantages of Tantalum Capacitors can be summarised:

Volumetric efficiency: Tantalum Capacitors offer a very high level of volumetric efficiency - much greater than many other types. In particular they are better than electrolytic capacitors which are their main rival.

Good frequency characteristics: The frequency response of Tantalum Capacitors is superior to that of electrolytic capacitors. This means that they are more suitable for use in a number of applications where electrolytics could not be used.

High reliability: Tantalum Capacitors are more reliable than many other forms of capacitor. Provided they are operated within their ratings they are able to provide an almost unlimited life. Their use is not time limited as in the case of electrolytic capacitors.

Wide operating temperature range: Tantalum Capacitors are able to operate over a very wide temperature range. They are often specified for operating over the range -55℃ to +125℃. This makes them an ideal choice for use in equipment for use in harsh environmental conditions.

Compatibility with modern production methods: Modern production techniques often expose components to high temperatures during soldering as the whole assembly is heated by infra-red heat. Using conventional leaded components only the board surface was heated and the amount of heat conducted by the leads was usually insufficient to damage the components. Tantalum capacitors are able to withstand the temperatures of SMT production and are there fore ideal for use in many new electronics designs.
