T541X108M2R5DH8605 is part of a range of tantalum-polymer capacitors developed and manufactured by KEMET Corporation, a leading global supplier of high-reliability surface mount components. It is particularly suitable for a broad range of applications including communications and power management. Through careful design and the use of state-of-the-art materials and processes, these capacitors offer excellent performance, long life and high reliability.

Tantalum-polymer capacitors are a type of specialized surface-mount chip capacitors. They consist of a tantalum anode and a thin polymer cathode layer, which is surrounded by a dielectric insulator. This construction confers several advantages over conventional aluminum electrolytic capacitors, such as small size, higher capacitance per unit volume, improved temperature characteristics, and extended shelf life. In addition, they have low ESL and ESR, superior reliability, and a wide operating temperature range.

The T541X108M2R5DH8605 is one of the smallest non-solid tantalum-polymer chip capacitors available today. It has an operating temperature range of -55°C to 125°C and a voltage rating of 25V. The maximum equivalent series inductance (ESL) is 0.05nH, with a relative dielectric constant of 8 and a dissipation factor of 0.0012 at 1kHz. With a maximum capacitance value of 10μF, it is ideal for use in high-frequency analog circuits, power supply decoupling, filters, and for RF shielding applications.

Tantalum-polymer capacitors feature ultra-low ESR, which is less than 0.007 ohms at one kHz. The low ESR ensures that power is distributed smoothly and efficiently throughout the board, without causing high spikes in current. As the current spikes increase, more heat is generated, which reduces the life of the capacitor. Moreover, their stability over a wide range of temperature makes them ideal for military and aerospace applications.

The working principle of tantalum-polymer capacitors is based on energy storage. When a voltage is applied, electrostatic energy is stored in the capacitor, resulting in the formation of an electrical field between the anode and cathode. This stored energy is released when the applied voltage is removed. The storage of electrical energy enables the capacitor to perform a variety of functions, including filtering, decoupling, and voltage regulation.

In conclusion, the T541X108M2R5DH8605 from KEMET is a highly reliable, compact and long-lasting tantalum-polymer capacitor. Its ultra-low ESR, long shelf life and wide operating temperature range make it an ideal choice for a variety of high-power, high-frequency applications, including communications, power management, filtering, and RF shielding.
