Tantalum – Polymer Capacitors

Tantalum - Polymer Capacitors are a type of tantalum capacitors. They are primarily used in high frequency and large voltage applications where high capacitance values, large energies and small physical footprints are required. The T540D687K2R5AH8505 is a tantalum-polymer capacitor with a large long-term reliability and high temperature performance. It is designed to provide a reliable and high-performance solution for extreme and high voltage applications.

Tantalum-Polymer Capacitors are constructed with a polymeric material, typically a polyphenylene sulfide film, coated onto an anode, a cathode conductor, and a dielectric layer of tantalum pentoxide. The polymeric material serves as a medium for the anode and cathode to be connected and for insulation between them. The dielectric is a very thin, usually between 0.001-0.008 µm, layer of tantalum pentoxide which provides the dielectric electrical insulator between the conductors. A liquid electrolyte, typically aqueous or organic, is used to maintain the electrical properties of the anode and the cathode.

The T540D687K2R5AH8505 typically provides an improved voltage rating that is well above standard electrolytic capacitors and supports maximum operating voltages up to 20V. It has a variety of advantages, primarily in terms of performance and reliability. Firstly, it has a much higher operating temperature range, operating from -55 to +125 C. It also has an extremely low ESR of 0.19 milliohms, a higher capacitance density (EIA 0805A to EIA 1210B), a larger capacitance range (2.5-680 uF) and a long life with a 1000,000h or 10,000h lifetime respectively. Additionally, it features increased vibration and shock resistance, a very low ESR, and high frequency and ripple current capabilities.

The T540D687K2R5AH8505 tantalum-polymer capacitor has had a broad range of applications, with primary usage occurring in medical, automotive, audio and avionics related products. It is also widely used in high frequency and large voltage power supply designs such as Buck Converters, Boost Regulators, Voltage Inverters, DC/DC Converters and more. They are also commonly used in industrial, defense and aerospace sectors, due to their high temperature and stable performance, compact size, and large energy density.

In summary, the T540D687K2R5AH8505 Tantalum-Polymer capacitor is a highly reliable and versatile component, capable of handling a variety of demanding applications. Its electrical characteristics, such as its high temperature range, high capacitance density, small size and low ESR, make it an ideal choice for a variety of applications, from medical devices to power supply designs. Its durability and performance make it the ideal component for a wide range of demanding applications.
