Tantalum - Polymer Capacitors (also known as tantalum electrolytic capacitors) are a type of capacitor that use a tantalum pentoxide layer as their dielectric material. The use of such a dielectric material allows for larger capacitance-voltage product with less dielectric loss. Aside from providing the typical properties such as low ESR, long shelf life, low-temperature performance and good leakage current, Ta-polymer capacitors also offer quite unique performance characteristics.

T55B156M020C0070 capacitors are particularly used on applications with high frequency and low ESR, such as high-end microprocessors, multi-segment filters, power management circuits, and high-density SM bus interfacing. These capacitors are not only energy efficient but also have very low ESR and ESL figures, thus providing improved system level performance at high frequencies. They are also known for their high stability and less temperature coefficient.

The working principle of Ta-polymer capacitors places its origin in a number of different materials and processes. To begin with, the Ta-polymer has its core in the materials andElectrolyte Solutions like SLA, MCA, and SLS, which are used to produce the anode and cathode terminations. These terminations are then placed in the electrolyte and polarized in opposite directions, thus creating a dielectric medium between the anode and cathode. As an electric potential is applied across the anode and cathode, an electric field is created and a current of charge passes through the capacitor, thus forming a capacitor in the process.

The electric field created by the passing current causes a charge to accumulate on the capacitors’ electrodes and electrostatic interactions occur that give rise to the capacitance of the capacitor. This capacitance is then determined by the electric field strength and the geometric factor, relating to the area and distance of the two electrode plates.

In order to ensure the capacitor works under certain range of temperatures, it is necessary to increase the dielectric\'s breakdown voltage with over-voltage recovery characteristics. This could be achieved by applying a special type of polymer, such as Tantalum-Polymer with the unique ability to retain its dielectric strength over wide temperature ranges. Thus, the Ta-Polymer can be used in high-temperature applications and will reduce the ESR and ESL values, thus ensuring better system performance.

When choosing a Ta-Polymer capacitor, it is important to consider a few factors, including the device’s capacitance, voltage, rated power dissipation and leakage current. As well, it is necessary to take into account the working environment and space limitations. Additionally, capacitors may come with different types of polarity and size options and these should also be considered when making a selection.

In summary, Ta-Polymer Capacitors are an ideal choice for a wide range of high-capacity applications with a reliable performance. They offer a high capacitance and low ESR at high frequencies and temperatures with a better stability and temperature coefficient. Due to their unique dielectric material, Ta-Polymer Capacitors are extremely durable and long-lasting and can be used in high-voltage applications and systems with increased reliability.
