T491A105M020AT Classification

Tantalum Capacitors

Tantalum Capacitors are high-performance capacitors made of tantalum metal as the anode material, and a layer of tantalum pentoxide (Ta2O5) is formed on its surface as the dielectric. Its uniqueness lies in the high dielectric constant and anode volume efficiency of tantalum metal, which gives tantalum capacitors significant advantages such as small volume, large capacity, low equivalent series resistance (ESR), low leakage current, and strong self-healing ability. The structure of tantalum capacitors enables them to operate stably at high frequencies, temperatures, and harsh environments, and are widely used in various electronic devices that require high reliability and long lifespan.

FAQ about Tantalum Capacitors

  • 1. Disadvantages of tantalum capacitors

    The price is relatively high.
    If used improperly or the circuit design is defective, it may fail, including explosion.
    It is polarity sensitive and can only work in the specified direction.
    It may fail easily under certain conditions (such as overvoltage, surge current).

  • 2. What is the expected life of tantalum capacitors?

    Under normal circumstances, it can range from thousands of hours to tens of thousands of hours, depending on the working conditions and manufacturer specifications.

  • 3. What causes tantalum capacitors to burn out?

    Common causes include applying a voltage exceeding the maximum allowable value, excessive current, high ambient temperature, and manufacturing defects.
