T521V156M035ATE100 Capacitors

Tantalum - Polymer Capacitors

T521V156M035ATE100 is a kind of polymer capacitor that is widely used in many applications due to their excellent electrical characteristics and robustness. It consists of a tantalum anode, a polymer electrolyte, and a cathode, which is usually made of an aluminum foil. The ceramic layer acts as an insulator between the inner and outer layers of the capacitor.

The main application field for T521V156M035ATE100 is voice and data communication systems, satellite communications, and radio frequency (RF) systems. This type of capacitor has favorable characteristics like good frequency and temperature stability, low equivalent series resistance (ESR), low equivalent series inductance (ESL), high volumetric efficiency, and high reliability in most of the common environmental conditions. Furthermore, this polymer capacitor is able to provide small size and high capacitance for a given voltage rating.

Working Principle

T521V156M035ATE100 employs a tantalum anode as its main component. The polymer electrolyte allows the electrons to travel between the anode and the cathode. The basic working principle of a polymer capacitor is the same as the conventional electrolytic capacitors, in which current flows through electrolyte and ions are moved by the electric field and deposited on the anode and cathode. Compared to the conventional design, the polymer capacitor has a larger surface area that allows more ions to be moved and stored.

The polymer electrolyte also allows the capacitor to have a higher working voltage than conventional electrolytic capacitors. The polymer material used in the electrolyte offers a very good electrical insulation that can reduce the risk of short-circuiting or overload. As for corrosion resistance, the polymer electrolyte is effective against the corrosive action of the electrolyte solutions.

Advantages

The major benefits of T521V156M035ATE100 are its small size, robustness, and high capacitance. This capacitor is also highly reliable, cost-effective, and can operate in a wide temperature range, making it ideal for voice and data communications systems. Moreover, its high volumetric efficiency means that, for a given voltage rating, the capacitor provides a high capacitance due to its larger surface area. Finally, its polymer electrolyte allows the capacitor to have a high working voltage and a reliable tolerance to environmental conditions.

Disadvantages

The main disadvantage of T521V156M035ATE100 is its price, which is relatively more expensive than the conventional electrolytic capacitors. Furthermore, the equivalent series resistance (ESR) and equivalent series inductance (ESL) of the capacitor can be relatively higher than those of the other capacitors on the market.

In conclusion, the T521V156M035ATE100 polymer capacitor is a reliable and robust component that provides excellent characteristics and performance. Its low cost, high capacitance, and wide temperature range make it suitable for many applications, such as voice and data communication systems, satellite communications, and radio frequency (RF) systems.
