Tantalum - Polymer Capacitors are a key component in the design of modern electronic equipment. Used widely in various applications, Tantalum Polymer Capacitors (TPCs) offer a major advantage in that they are smaller in size than conventional aluminum electrolytic capacitors and feature lower leakage current and better electrical characteristics. The combination of their size, performance, and overall cost-per-chemical weight make TPCs an excellent choice for applications where high performance is required and space is limited. The T521B155M050ATE200 is one such TPC and its fields of application, as well as its working principles, are the focus of this article.

The T521B155M050ATE200 is a high-performance, high-current, high-capacity TPC designed for applications such as power supply, lighting, power conversion and control circuitry. The capacitor is capable of handling very large currents and can handle up to 1 A at 25°C. It provides excellent noise suppression, low levels of leakage, and has a very low equivalent series resistance (ESR) value. It offers both high capacitance and low ESR values, making it ideal for applications such as power supply filtering. With a rated voltage of 5 V and an operating temperature range of -40°C to 85°C, the T521B155M050ATE200 is more than capable of handling a wide range of conditions, making it a very reliable capacitor for design and production.

Regarding the capacitor’s construction, the T521B155M050ATE200 from Toshiba is built from a combination of a tantalum anode, a polymer sleeve and an anode-electrolyte material. The tantalum anode is a highly robust and stable material, capable of providing reliable operation over extended periods of time. The anode-electrolyte material is also a very important part of the capacitor structure, and is responsible for the low ESR values and high capacitance. Finally, the polymer sleeve provides a strong seal between the anode and the electrolyte material, preserving the integrity of the capacitor.

From an operational point of view, the T521B155M050ATE200 capacitor works by relying on the basic principles of capacitance. When a voltage is applied across the capacitor, a current flows from the anode terminal to the electrode-electrolyte material, creating an electric field in the process. This electric field produces an opposing electrical charge on the capacitor plates which separate the anode and the electrolyte material, thereby storing energy and thus creating the desired capacitance. As the voltage across the capacitor drops, the electric field weakens and the current decreases, ultimately discharging the capacitor.

To conclude, the T521B155M050ATE200 from Toshiba is a high-performance, high-current, high-capacity TPC that is perfectly suited for applications such as power supply, lighting, power conversion and control circuitry. It provides excellent noise suppression, low levels of leakage, and has a very low equivalent series resistance (ESR) value. Its combination of size, performance, and overall cost-per-chemical weight make it an excellent choice for designs where high performance is required and space is limited. In terms of its construction, the capacitor is comprised of a tantalum anode, a polymer sleeve and an anode-electrolyte material. Finally, its working principle is based on the basic principles of capacitance, whereby it uses an electric field to store energy and produce the desired capacitance.
