Application of T521D476M020ATE055

Tantalum-polymer Capacitors are widely used in electronic devices that require high stability and high power density. In computers and servers, they are used in power management circuits to ensure a stable voltage supply and improve system efficiency. In mobile communication devices such as smartphones and tablets, tantalum polymer capacitors are favored for their miniaturization and high energy efficiency for filtering and voltage regulation, thus guaranteeing signal quality and battery life. In automotive electronics, such capacitors play a key role in engine control units, airbag circuits and entertainment systems, especially in harsh environments where stability and reliability are critical. Tantalum polymer capacitors are also indispensable in medical devices such as pacemakers and portable monitoring devices, providing precise energy storage and release for patient safety.

T521D476M020ATE055 Classification

Tantalum - Polymer Capacitors

Tantalum-polymer Capacitors are high-performance capacitors whose core components include Tantalum metal as an anode, a surface layer of tantalum oxide film as a dielectric, and a Polymer as a cathode. This unique structural design gives tantalum polymer capacitors high capacitance values, low ESR(equivalent series resistance), high ripple current capability and excellent stability. Compared to conventional tantalum capacitors, tantalum polymer capacitors perform better in terms of high frequency performance and reliability, making them particularly suitable for applications that require efficient storage and release of energy in a compact space. Due to the use of polymer cathodes, these capacitors also have excellent self-healing capabilities, which means they can self-recover under overvoltage conditions and extend their service life.

FAQ about Tantalum - Polymer Capacitors

  • 1. What is the difference between regular capacitors and tantalum polymer capacitors?

    Construction: Regular capacitors can be non-polar (such as ceramic capacitors) or polar (such as aluminum electrolytic capacitors). Tantalum polymer capacitors are always polar and use a solid conductive polymer as the electrolyte.

    Performance: Tantalum polymer capacitors generally have lower ESR, better frequency characteristics, and higher stability.

    Applications: Due to their high performance characteristics, tantalum polymer capacitors are often used in electronic devices with high performance requirements.

  • 2. Will tantalum polymer capacitors deteriorate?

    All types of capacitors will experience a certain degree of aging over time. For tantalum polymer capacitors, although the aging rate is relatively slow, they may still experience problems such as capacity loss after long-term use. In addition, improper storage conditions or excessive operating temperatures can also accelerate this process.

  • 3. Which side of a tantalum polymer capacitor is the positive pole?

    Usually, there is a clear mark on the tantalum polymer capacitor to indicate the positive pole, such as a long bar mark or a "+" symbol.
