  • Tantalum Capacitors

    These capacitors offer a very high charge per unit of volume, a long lifetime and a high reliability. They are used in consumer goods and more specialized niches including space vehicles, aircraft electronics, weapons and rail transport. Exxelia develops both solid and wet tantalum capacitors.

  • What are the Benefits of Tantalum Capacitors?

    A tantalum capacitor is a specific type of electrolytic capacitor. It is made from a metal called tantalum, which is where it gets its name. Tantalum acts as an anode. The capacitor itself is covered in a thin layer of oxide, which allows it to act as the dielectric. It is surrounded by a conductive cathode. One of the major benefits of tantalum capacitors is that their design allows for a very thin layer of dielectric, which allows for higher capacitance than other types of capacitors made from different types of materials. These types of capacitors are generally polarized, which means that in practice they can only be connected to a direct current power supply that has been designed while observing the appropriate terminal polarity. They have excellent stability over time and superior frequency characteristics when compared to different types of similar capacitors that are made from different materials.

  • Less Space for Greater Packing Density

    Tantalum capacitors are commonly used in a wide variety of different types of electric circuits. They are often found in various applications throughout the automotive industry, in laptop and desktop computers, in small mobile devices like smart phones or tablets and other types of electronic components. The most common form of tantalum capacitors comes by way of surface mounted devices. These types of capacitors are important for those devices because they take up much less space on a circuit board, which therefore allows for a greater packing density.

  • Advantages and Disadvantages of Tantalum Capacitors

    One of the most important characteristics of a tantalum capacitor is its polarity. By and large, these types of devices are known to be very polarized devices. When compared to capacitors made from other materials like aluminum electrolytic capacitors, they have a number of clear advantages. There are also a few distinct disadvantages. An aluminum electrolytic capacitor has the potential to survive reverse voltage that has been briefly applied, for example. Tantalum capacitors themselves are sensitive to reversed polarity and could show the potential for a short circuit.

    Another key characteristic of the tantalum capacitor is its failure mode, which could be potentially dangerous under the right conditions. In the event of a voltage spike, if the circumstances align just right it could start a chemical reaction would could produce heat, smoke and even flame. External failsafe circuitry is often used in association with devices that use tantalum capacitors to prevent just these types of events. It should be noted that due to the presence of these types of fail safes and other precautions that are taken during the construction of tantalum capacitors, the potential for dangerous situations is very limited.
