Tantalum Polymer Capacitors, designated by the T code followed by a number, is a type of capacitor that combines two of the most popular technologies in the capacitor world, tantalum and polymer. This combination has created a superior quality capacitor that offers some unique advantages that are unavailable with other types of capacitors, such as extremely low equivalent series resistance (ESR), high capacitance retention ratings, and an excellent volumetric efficiency. In electronic applications such as computers, cellular phones, and military applications, the superior reliability of these polymer tantalum capacitor products means a longer lifetime and higher performance capabilities.

The T521B225M050ATE2007280 is a type of polymer tantalum capacitor with a farad rating of 5.21, an operating temperature range of -55 to +105 degrees Celsius, and a nominal voltage rating of 10V. The M series indicates a standard size, as opposed to other sizes such as S and L series, and the T indicates a temperature rate of 80%. The ATE means the capacitor is of superior quality, and the ATE200 part means the rated capacitance tolerance is at ± 20 percent. A capacitance tolerance rate of ± 20 percent indicates a higher level of reliability than a standard capacitor with a tolerance rate of ± 10 percent.

Application Field

Tantalum polymer capacitors are mainly used for power applications, such as DC/DC converters, and high capacity filtering. Since these capacitors offer excellent volumetric efficiency and high capacitance retention ratings, they are used in applications that require a large amount of capacitance in as small a package as possible. In addition, they are used wherever a low ESR and a high capacitance retention rating are essential, such as in servers, signal conditioning, and high-current discharge applications.

Tantalum Polymer Capacitors are also seen in a variety of consumer electronics. In devices such as portable media players, digital photography equipment, and mobile phones, these capacitors are used for filtering, decoupling, and bypassing applications. In addition, these super capacitors are often used for powering low-voltage microcontrollers, and other applications requiring high energy density with ultracapacitor technology.

Working Principle

Tantalum Polymer Capacitors work like other capacitors in the sense that they store a charge, but the capacitor is constructed differently. Instead of using electrodes made of a metal oxide, the electrodes in a tantalum polymer capacitor are stacked layers of flexible, conductive polymer. This construction allows for the capacitor to maintain its volumetric efficiency and to withstand harsh environments. In addition, the polymer dielectric offers a lower ESR than a similar electrolytic capacitor, which increases the capacitor’s ability to deliver higher energy levels.

Tantalum Polymer Capacitors also offer excellent temperature stability. This is due to the fact that these capacitors are solid state, meaning that the dielectric is not a liquid or gas, but a solid material. This improves the capacitor’s temperature stability and also allows for a high capacitance retention rating.

In addition, these capacitors can accommodate a wide range of voltage levels, and are capable of withstanding large inrush currents. This makes them ideal for high-current applications such as automotive and high-power industrial applications. They are also well-suited for high frequency and high vibration environments, making them an excellent choice for communication, military, and aerospace applications.

Overall, Tantalum Polymer Capacitors are an excellent capacitor choice when quality and reliability are a paramount concern. They offer an excellent combination of low ESR, high capacitance retention, a wide operating temperature range, and a high volumetric efficiency that make them perfectly suited for many different applications.
