Tantalum capacitors are electrolytic capacitors which consist of two electrodes - a foil anode and a wire cathode. The foil anode is usually a porous structure on which tantalum pentoxide layer is formed by an electrolytic process. Due to the low volumetric efficiency of traditional electrolytic capacitor designs, these tantalum capacitors are advantageous in terms of size, temperature stability, capacitance stability, low impedance, and volumetric efficiency. The application field of these capacitors has become more and more expanded, and you can find these tantalum capacitors in applications such as telecommunications, computers, consumer electronics, and power electronics.

The T86C475K035EAAS is a high-grade, small size, low profile, modified version of the ordinary tantalum capacitors, and it is widely used in space-constrained applications. It is a molded drop-in, multilayer capacitors with high temperature (+110°C) rating. The working principle of the T86C475K035EAAS is quite basic; it functions as a normal capacitor does, storing energy in an electric field. However, the way in which it stores energy is different from ordinary capacitors.

Tantalum capacitors store energy in the form of a tantalum pentoxide film that is formed as an electrolytic process. A capacitor dielectric is formed in between the foil anode and the wire cathode, and this dielectric is made of an oxide film which makes up the capacitance of the capacitor. This film is made up of volatile electrolyte solution and follows the general work principle of electrolytic capacitors.

The working principle of tantalum capacitors is based on the properties of their construction. The dual layer structure consists of an anode foil and a wire cathode which are immersed in a dielectric solution. As electric current is passed through the dielectric solution, a polyoxymethylene (POM) powder is formed on the anode foil by an electrolytic reaction. This POM powder acts as a dielectric system between the anode and the cathode, and prevents the flow of electrons.

The T86C475K035EAAS combines the benefits of low profile, small size, and high temperature rating with excellent capacitance stability over temperature and frequency. It is also designed to have a wide range of temperature coefficients of capacitance, from -75 to +20 ppm/°C. This makes it ideal for applications that require an extended temperature range and the highest levels of capacitance stability.

The T86C475K035EAAS also offers a wide variety of options to design engineers, including the ability to choose between terminals, along with a wide range of capacitance values from 0.1 to 1000 μF. In addition, the T86C475K035EAAS has a high ripple current capability and a long-term reliability. This makes it suitable for use in a variety of applications, ranging from consumer electronics to power electronics.

The T86C475K035EAAS is an excellent example of a tantalum capacitor and showcases the capabilities of these capacitors. While traditional electrolytic capacitors are limited by their size, temperature stability, capacitance stability, and low impedance, the T86C475K035EAAS is designed to be able to overcome those limitations. It is an excellent choice for applications which require a higher level of performance, and its wide range of options makes it very versatile.
