Tantalum - Polymer Capacitors are widely used in a variety of applications due to their small size, large capacitance and excellent high frequency characteristics. The 2R5TPF470ML is a very popular family of these capacitors and is designed for applications such as DC blocking, bypass and decoupling. The capacitors consist of a tantalum anode, an electrolytic polymer dielectric and a polyaniline cathode.

The 2R5TPF470ML has a wide range of working voltages to provide optimal performance in applications from low to high temperatures. It has a capacitance from 47uF to 473uF and can operate up to an extremely high voltage of 10V. This makes it suitable for use in a variety of applications such as power supplies, mobile devices, signal processing and automotive electronics.

The working principle of the 2R5TPF470ML is based on the electrochemical phenomenon of dielectric absorption. The voltage applied to the capacitor causes an increase in the external electric field. This causes the electrons in the capacitors to become more mobile and form a charge-storage layer on the surface of the dielectric. This layer is known as an oxide layer and is responsible for the high capacitance values.

Furthermore, the 2R5TPF470ML have a low equivalent series resistance (ESR) and superior temperature characteristics. The low ESR is attributed to the polymer dielectric which provides a low resistance path for the current. The capacitors also have a low equivalent parallel capacitance (EPC) which allows high speed pulse discharge. Consequently, these capacitors are well-suited for energy storage applications and in high frequency circuits.

In conclusion, the 2R5TPF470ML is a popular family of polymer tantalum capacitors that can be used in a variety of applications. They have a wide range of rating voltage and capacitance values, high capability for high-speed pulse discharge and excellent temperature characteristics. Due to these features, they are suitable for a range of applications including power supplies, mobile devices, signal processing and automotive electronics.
