Tantalum - Polymer Capacitors

Tantalum-Polymer Capacitors (TPCs) are a type of electrolytic capacitors that combine the high capacitance of tantalum with the good dv/dt performance of organic polymer materials. A TPC typically consists of a tantalum anode, a nonconductive organic polymer electrolyte and a conductive polymer cathode. They offer superior performance and reliability compared to other types of DC etching capacitors, making them a popular choice for various applications including high-power motor drives, power management ICs for computing and digital audio/video hardware, cellular base station RF power amplifiers, and medical implants.The T540B157M003AH8710 is a surface-mount TPC from KEMET Corporation. It has a nominal capacitance of 15µF, a rated voltage of 10V, and a rated temperature range of -20°C to 85°C. The T540B157M003AH8710 is designed for high-temperature and high-relief applications and features a broad range of RC and ESR values.The working principle of a TPC is based on the same concept as other electrolytic capacitors. An electrochemical reaction occurs between the tantalum anode and the polymer electrolyte, allowing electrical current to be stored and released when needed. This electrochemical reaction provides the charge when the capacitor is connected to a DC voltage source, and current passes through the capacitor towards the anode. As the current flows, the electrolyte polymerizes and forms a semi-permeable polymer film between the electrodes. This film absorbs free ions and traps charges, creating an electric field that stores electrostatic energy.The T540B157M003AH8710 is widely used in applications which require high ripple current and withstand high temperature. Due to its robust construction and electrolytic film, it offers excellent reliability and long life performance. Its low ESR and highlighted capacitance at high ripple current makes it a great choice for power supply unit (PSU) and DC-DC conversion filtering applications. It also shows outstanding performance in audio/video system energy storage as well as LED bulbs and displays. Thanks to its low profile package, the T540B157M003AH8710 can be placed in tight spaces, making it ideal for compact electronic circuits. It is also RoHS compliant, lead free and fits low-inductance configurations for better filtering and better noise suppression.Overall, TPCs offer convenience and reliability in a wide range of applications with their high voltage and broad temperature range. The T540B157M003AH8710 is a reliable, high-performance TPC that’s widely used in a variety of applications.
